Sandboxie is an interesting alternative to traditional anti-virus/anti-spyware software. According to the developers, when you run a program on your computer, data flows from the hard disk to the program via read operations. The data is then processed and displayed, and finally flows back from the program to the hard disk via write operations. For example, if you run the Freecell program to play a game, it starts by reading the previously recorded statistics, displaying and altering them as you play the game, and finally writing them back to disk for future reference.

Sandboxie changes the rules such that write operations do not make it back to your hard disk. The key is the transient nature of the sandbox which makes it easy to get rid of everything in it. If you were to throw away the sandbox, by deleting everything in it, the sandboxed statistics would be gone for good, as if they had never been there in the first place. You maye in fact prefer to run your Web browser inside the sandbox most of the time. This way any incoming, unsolicited software (spyware, malware and the like) that you download, will be trapped in the sandbox. Changes made to your list of Favorites or Bookmarks, hijacking of your preferred start page, new and unwanted icons on your desktop - all these, and more, are trapped in and bound to the sandbox.

This is a very original solution to the perennial problems caused by adware, spyware and malware. However, it's dubious as to whether it can deal with the continual sophistication of such programs.

When it comes to P2P file sharing, eMule usually wins hands down but UseNeXT is an interesting, slightly more sophisticated offering which has a lot to offer.

For starters, depending on your connection, it can be remarkably quick. You can download at speeds of up to 25 Mbps with DSL/Cable and it¡s pretty constant rather than the fluctuations you often get with such services. The network also prides itself on security over it's rivals such as Limewire and eMule - with ISPs continually cracking down on users, UseNeXT promises users far more anonymity than most.

The Usenet archives are supposedly some of the biggest in the world - more than 300 Terabytes of data available at all times and they claim that around 2,000 Gigabytes of new files are added daily. The problem in the past was that UseNeXT used to be a very complicated affair that only tech geeks can handle. However, nowadays, it's been simplified to such an extent that eMule, Limewire and other P2P users will feel more than comfortable with it.

While it can't possibly hope to compete with the reach and depth of the major P2P networks, UseNeXT offers an impressive selection with some super fast downloads.

Trojan Remover is designed to aid in the removal of Trojan Horses and Internet Worms when standard anti-virus software has either failed to detect the problem or is unable to effectively eliminate it.

The majority of Virus and Trojan Scanners are able to detect malicious Trojan Horses and Internet Worms but aren't always very efficient in removing them once triggered. Trojan Remover aims to carry out such a removal without the user having to manually edit system files, including the Registry. The application removes the additional system modifications that some Trojans carry out, which are often ignored by other Virus and Trojan Scanners.

A smart freeware program that can clear all forms of mal-ware from your computer. Spybot S&D is a powerful application that offers a default mode and an advanced mode.

When you install this program, you are immediately given the choice to update, which is of course all important when dealing with the various forms of spyware that you want to be protected from. Unfortunately, when updating, progress can seem rapid and then stop for no apparent reason, for several minutes before finishing off the job.

Once you get over that small hiccup, you are prompted to create a system backup, just in case the program happens to remove something that is actually quite important for the smooth running of your system. It should go without saying that making this backup is recommended after which you may finally immunize your system from a growing database of malicious processes.

The program has plenty of options for tweaking and customizing scans as well as some unrelated functions like the secure shredder and a start-up manager.

Although this is a powerful piece of anti-spyware software, it may be better to see it as part of your security solution. For example, team this up with Ad-Aware SE and you should be covered from practically every form of threat to your online safety.

Antivirus tools are the kind of software applications that you need to use for an extended period of time in order to fully test them. Still, having only a few hours to try Kaspersky Anti-Virus, I must say I got a really positive impression.

After a slightly troublesome installation process which included the eventual uninstalling of other antivirus apps plus an updating process, you're ready to launch Kaspersky Anti-Virus and let it take care of your computer. In fact, it monitors not only the file system, but also email and web browsing, thus providing you with a comprehensive security solution that will keep you safe from today's most usual dangers on the Web.

Kaspersky Anti-Virus features several different scanning modes (Critical areas, My computer, Startup objects and Rootkit scan). Each one of them can be run manually or programmed to run according to a certain period of time. You can also define your own scan mode and set an exception list for those files, folders and apps that you trust and needn't be scanned. One thing I particularly liked is the possibility to create a rescue disk, in case your PC is completely ruined by a virus attack.

Kaspersky Anti-Virus seems very light on resources, which is always good in a program that you must have constantly running. However, files and apps may take slightly more time to open while Kaspersky Anti-Virus analyzes them. I guess this is a small price we have to pay for being a bit more secure. In any case, you may as well use the exception list and make sure all your trusted apps are included there.

Kaspersky Anti-Virus offers a complete protection against virus, Trojans and worms for your file system, email and web browsing.

Free anti-virus software can be a mixed bag - sometimes they can do more harm than good while at others, they can save you hundreds of dollars with solid real-time protection.

Avira AntiVir PersonalEdition Classic is the free version of Avira AntiVir PersonalEdition Premium. This doesn't mean that it's any less powerful bit it does mean that many advanced features are unavailable. The program can scan up to 30 different file types and seems to have been designed with a particular focus on Trojans according to the developer blurb. Protection is served in real time and as with all virus scanners, you are immediately given the choice whether to ignore, quarantine or delete the infected file. What's nice about this scanner is that for those viruses that it can't identify or clean, it compiles a report which can then be automatically submitted to Avira's lively user forum where someone, somewhere, should be able to help. The scanner sits in your system tray bit can be expanded to show the current settings and the status of any scans in progress. Scanning is quick and it doesn't slow your machine down significantly. Unfortunately however, it provides no option for scanning incoming and outgoing mail or adware/spyware but if you're just looking for a trojan blocker/remover, it's a very solid product.

A powerful and well organised anti virus scanner that helps you get to the bottom of virus issues rather than hinders your progress.

In the never ending battle against spyware and adware that infects Windows with alarming regularity, Spy Emergency is a comprehensive security option.

This program claims to cover just about anything - malware, spam, spyware, adware, virus, trojans, worms, homepage hijackers and much much more. In other words, it's just about the most all-round solution you can find for attacks and other nasties that try to attach themselves to your system. The program follows the regular format of most anti-spyware software but doesn't overwhelm you with unnecessary options and dials. Clicking the "Start" button initiates scans and at the completion of a scan, you're asked to review the results and decide which items you want to remove. Items are ranked in order of potential threat so you can see at a glance which ones pose the biggest threat. Another plus to this system is that unlike many spyware checkers, it's remarkably light on system resources which makes it a good option for those on older machines.

Although I'm not convinced it's removing everything it should, it's still a very comprehensive product that has all possible angles of attack covered.

Registry problems are the most common reason for Windows PC to slow down and performance issues.

Reg Repair is a free registry cleaner utility which claims to delve deep into your Windows registry and find and fix potential causes of performance problems. The first problem you may encounter when installing this software however is that your antivirus checker may detect it as spyware. The reason is that it requires access to your registry which all good spyware and anti virus scanners protect. It's also because the program tries to establish a secure (https) connection with Digital Support online service which it needs to perform checkups and be updated with the latest registry threats. You may see "dsweb" displayed at some point in the alert which refers to the utility that checks for updates. The one unusual aspect of this program is that, after the simple scan and presentation of results, you can be linked directly to one of the developers online support technicians to work out what the problem is and whether it is a threat. Of course, you have to pay for this service although you can perform a basic clean for free at your own risk.

A quick and simple registry cleaner that features support from real engineers in case you are unsure or worried about deleting a particular registry entry.

There are many anti-virus, anti-spyware and anti-dialer software products but only a few of them can claim to provide effective protection from all types of Malware. The main reason for this is the eternal cat and mouse game played for decades between Malware programmers and the security industry.

Normal security software is limited by the fact that it can only recognize Malware for which the manufacturer has already created a signature - assuming that the manufacture even has a copy of the Malware available for analysis.

Emsi Software has now turned the tables and no longer trails behind the Malware authors. a-squared Anti-Malware does not identify damaging software purely on the basis of signatures, but also looks at how it behaves. This means that you will be protected from the hundreds of new Trojans, Worms, Dialers, Rootkits and Spyware that appear every day.

Morpheus is one of those age old P2P applications and, with support for Gnutella, eDonkey, Bittorrent and many others, probably the most versatile you can find on the market. The new version aims to turn the P2P client into the ultimate multimedia application. Does it succeed?

Morpheus has gone through a complete facelift and the new version brings a newer interface. The window is divided into 4 tabs: search results, my files, podcasts and Morpheus online, giving you an idea of what it considers important. A pane on the left side allows you to create playlists or keep track of searches and videos – although strangely not music. Morpheus lets you also sync all your downloaded files to import them automatically to iTunes. Oddly enough, the chat tool is now hidden at the top of the interface, next to help and preferences.

Morpheus wants to appear as a multifaceted app, not just a simple P2P program. It includes an embedded browser, Morpheus Online, from which you can check-out the internet or find new files to share while you’re downloading. This is particularly useful when you’re looking for new podcasts. By clicking on the podcast page button in the podcasts tab, you will be taken to Morpheus’ own podcast library. While it’s not as star studded as the iTunes library, it’s full of varied and original content. The podcast tab is wisely divided into podcast and episodes, so you can browse through what you’ve downloaded. However we were quite confused by the whole podcast downloading procedure. The progress bar is hidden in the file window of the My Files tab. Why didn’t Morpheus leave this in the podcast section?

Morpheus has also beefed-up its security. You can now select your antivirus application to automatically scan downloaded files. The program also includes solid parental control so you can enter hazardous terms into the block list to avoid your kids searching for violent or pornographic material. You can also add a password to make sure you control who has access to Morpheus. The application also introduces UDP technology to improve the performance of downloads and allow secure file sharing between 2 firewall protected PCs.

This new version comes with many interesting enhancements, but not enough to get us overexcited. Add to that the many drawbacks we found in the application. The interface for example is way too clunky, and it’s safe to say that lies in the two large ads at the top and the bottom of the program (which disappear if you buy the Pro version). The “My Files” tab has an additional file window at the bottom, which adds to the confusion in the interface. The one click burning function is something we were eager to try out but was nowhere to be seen.

However hard Morpheus tries at integrating cool features like web browsing or podcasting, we figure the application should only be used for what it’s good at i.e.P2P downloading. The program gives access to all the P2P networks, even Bittorrent, and the new version introduces safer and quicker transfer thanks to UDP technology. The other extra features in the application like the library structure or web browser felt a bit awkward, and therefore failed at turning the program into a true multimedia application. Let’s hope Morpheus gets it right in the future.

We've all been in that horrible scenario where an essential file has seemingly disappeared into thin air - either via accidental deletion or malware which has invaded your system.

First thing's first - this is no substitute for an anti-virus checker but it does offer you extra protection against the worst case scenarios in file deletion. It's mainly aimed at those that want to protect their files from kids or another unauthorised users that may purposely or accidentally delete files. Of course, if you are using Windows, I suggest the best way to do this is is to create an entirely new user profile for each person but if this is not possible, then this is an excellent alternative.

System Protect allows you to pick those files and folders that you want to protect such as important documents, your favorite music, vacation photos, movies etc. It's best used as an extension to your currently existing security suite. to keep your system stable and get automatic deletion alerts - a virus checker may inform you of a virus attack but it won't tell you whether the target is going to be deleted - System Protect will.

If you don't have much faith in your antivirus software or are worried about other users on your PC, then this is an excellent solution.

Have you ever wanted an open-source portable anti-virus solution that you can use anywhere at anytime?

Protect Simple Machine is just that - a portable and free anti-virus app that fits on your USB pen and makes sure that the computer you are using is not infected by viruses, worms, Trojan horses or spyware. Created with Visual Basic, the program is incredibly simple to use and can analyze any folder or disk you choose. It also advises you on ways to "tweak" Windows so you can optimise Protect Simple Machine for more effective, faster use. It also has direct links to other Windows tools such as the command line.

Nowadays, one of the most important areas to scan is the memory and Simple Machine Protect also caters for this with a memory scanner which works alongside the disk scanner. The program warns you if it finds a virus with a very primitive "beeping" sound and it can sometimes repair them on the spot, depending on whether the database is equipped with a sufficient solution. At all times, the program lets you know at what stage the scan is at with a progress bar.

A very convenient solution for those on the move although it's a bit lightweight and tends to miss minor viruses and Trojans that more solid scanners pick up.

Symantec is a company that has been subject to criticism for dropping the ball with recent versions of their anti-virus and internet security software, so does their backup solution show any proof that they are building on their vast experience and that their popularity and reputation is somewhat justified? At first sight, it’s clear that the interface has followed in the footsteps of every other Norton product, meaning that you get a user friendly tabbed based window with a healthy quantity of wizards thrown in for just about every operation.

Unfortunately the make-over seems to have just touched the surface and as a result, each tool you want to use will open a new window. Not only can this lead to a cluttered desktop with lingering dialog boxes but may also cause your system to slow significantly or at worst, crash. Used properly though, Norton Ghost will let you backup your entire hard-drive to another partition, an external, or a networked drive on a regular scheduled basis and also gives you a variety of ways to restore the reserve copies should the worst happen.

For anyone with huge amounts of data to backup, the option to compress everything will come as a blessing and for those with sensitive documents there is password protection and encryption. What’s more, the processes involved have been completely dumbed down, with less jargon and step by step instructions. While this benefits those who want a backup solution that they install and forget about, it strikes more advanced users right where it hurts. You can’t even select what folders to back up and instead must be satisfied that it’s all or nothing.

Although the program didn’t seem to be entirely stable, there was no obvious hit to system performance, which was one of the main problems with other Symantec software. Norton Ghost will put your mind at rest with a comprehensive copy of your hard drive, but if you prefer to be in complete control or to restrict your backup to only your essential files, then you should look elsewhere.

The program features anti-phishing protection to stop you getting sucked in by malicious sites and it also features 24 hourr support if you upgrade to the full version. This latest release also features a Gamer Mode which temporarily modifies protection settings so as to minimize their impact on gaming performance, maintaining a safe, fun gaming experience.

ThreatFire, previously know as CyberHawk, is a pre-emptive anti-spyware monitoring tool that aims to protects you from malware before it gets anywhere near your system. It does this by monitoring the behaviour of your PC in real time to check for strange or irregular behaviour.

This method supposedly offers faster protection as you don't need to wait for an anti-virus signature file to be updated as with conventional antivirus programs. However, ThreatFire can interpret any kind of new behaviour on your PC as a threat and it can be rather annoying to get warnings and prompts every time you install a new piece of software. However, you can configure it to "trust" certain activity so you can minimise annoying messages in this way.

Obviously, ThreatFire monitors your PC in real time, but you can also configure it to run on demand although it seems there's no way of knowing the progress of these scans. Note that because this program is designed to protect your PC, it can be hard to fully close it down. Even when you've closed the window, it will run in your taskbar and even closing it from there is not clear. Overall though, this is an interesting alternative to conventional anti-spyware.

Security is the one issue that concerns computer users all over the world. No wonder security apps are the most downloaded applications.

Secunia is one of those security apps but in a rather original way. Instead of protecting your system against virus, setting a firewall to avoid unauthorized connections or watching ports to prevent intruders, Secunia revises all your installed software applications and makes sure you have the latest versions for them all. This is just another way to keep your system safe, as updated versions usually include safety fixes and solve potentially harmful bugs from previous ones.

Secunia was very effective during our tests: it took it only a couple of minutes to scan the whole system and soon discovered my outdated Firefox (shame on me!). But what I didn't like about Secunia was its alarming tone. The program makes such a display of warning messages, alert icons and other similar items that you end up having the impression that your PC is about to blow up just because you didn't update your browser on time.

Despite being some sort of scaremonger, Secunia can be very helpful to keep your software up to date.
