The battle against trojans and spyware is a constantly ongoing one but there's no need to spend big money on expensive solutions.

a-Squared is a free anti-spyware/anti-malware scanner that can pick up just about anything that's illegally installed itself on your system. It frees your PC from malware after a simple and fairly quick scan to improve your PC performance and reduce any performance or internet related problems. However, this is one program that does so with caution which is a refreshing change. Instead of just wiping anything off your system, it places those components that are critical to system performance in quarantine meaning that there is less chance of your system becoming unstable after a scan. The program is regularly updated although unfortunately not automatically - you have to instruct it to perform an online update at periodic intervals. The program has clearly been designed with beginners in mind - there are no complicated scanning functions or strange components to deal with. It reminds me somewhat of CCleaner and in a way, performs a similar job but with a focus on malware instead of temporary files.

An extremely simple and affective malware scanner, it should pick up any illegal software that's attached it self onto your system in a safe and secure way.

AVG Anti-Rootkit is a new program from the creators of AVG Antivirus that aims to get rid of pesky and stubborn rootkits. If you don't know what rootkits are, they're basically tools that come somewhere between viruses and Trojan horses. In effect, they leave your computer highly vulnerable to external attack

As you might expect from an AVG product, it's pretty simple and straightforward to use. In fact, it only has two main buttons - a general review (which runs much faster) or an in-depth examination of the drives you want (which is more through but takes longer). If there are any rootkits on your system, then this program will almost certainly get rid of them as it can find even the most hard to get NTFS-ADS objects. One nice touch is that the developers have included a special interface for visually impaired people that simplifies the process even further.

If you fear that your computer is vulnerable to external attack, and your anti virus has failed to help, then give AVG Anti-Rootkit a go and it will almost certainly reveal the culprit.
