WHAT'S THE MEANING?
Application Package Kits or APKs are file formats used in distributing and installing software in Android-supported devices. These files end in .apk, similar to how files distributed and installed in Windows-supported devices end in .exe. APK files or APK version of files are usually used to retrieve files that are not on the Google Play Store, and are likely to be a threat to devices that use them.
DID YOU KNOW?
There are many ways to make sure downloading APK files will not harm your phone or tablet. One is using Virus Total, a website that offers a free quick check of files and websites to see if these files and websites have malware or suspicious software. Second is using OPSWAT's Metadefender, a site dedicated to cybersecurity and can look for malware in APKs that are as large as 140MB. This website is one of the most reliable APK scanner since it also investigates IP addresses, offers a list of malwares, and reports common loaded libraries for executables and crowd-sourced network traffic. The third is the NVISIO APK Scan, another free website used for looking for malware in package kits but requires users to input email addresses and answer captcha puzzles. With these sites, anyone can make sure whether the APKs from sites like APK4Free and DownloadAPK4u are safe for installment.
