A-Squared Free is an extremely robust anti-spyware software package that touts the ability to remove adware, spyware and malware in addition to trojans, backdoors, keyloggers, rootkits, worms, bots and dialers. Despite the fact that A-Squared Free is, well, FREE, it is still a full featured piece of software to help ensure the security of your computer.

The main difference between the free and pay versions is real-time scanning. You will have to manually run A-Squared Free to make sure you are not infected.

Keep in mind, this is not an alternative to an Anti-Virus program. Make sure you are still protected with a program designed for viral issues.
