More free malware killers

From firewalls and antivirus software to tools for combating rootkits and spyware, here are some great downloads that will protect your system against malicious attacks.

AVG Anti-Rootkit


One of the most feared types of malware is the rootkit. Bad guys use rootkits to hide Trojan horses, which can then be used to take over your PC without your knowledge.

AVG Anti-Rootkit's sole purpose is to find and kill rootkits. It scans your PC, sniffing rootkits out and removing any it finds. It will be part of the upcoming AVG 8.0 security suite, but you have to pay for that! Download AVG Anti-Rootkit here.

Spyware Blaster


Some of the nastiest kinds of spyware install themselves as ActiveX controls. Spyware Blaster protects you against them, blocking the installation of ActiveX-based malware and other spyware and eradicating tracking cookies that might invade your privacy.

The program works with Firefox, Opera or IE (Internet Explorer) to prevent your browser from being diverted to dangerous sites. One particularly nice touch is the utility's System Snapshot, which takes a snapshot of your PC.

If your computer gets infected later on, you can revert to the clean version.

AOL Active Security Monitor


This straightforward application looks at the security of your PC, reports its findings and makes various recommendations.

It checks you have antivirus software installed and, if so, whether the definitions are up to date. Then it does the same for antispyware, tests whether your firewall is enabled and checks for peer-to-peer software that could pose a danger.

The monitor doesn't have any protective capabilities itself, but it warns you if you need some. But take its recommendations with a grain of salt: it touts paid-for AOL software over free (possibly better) software. Download AOL Active Security Monitor here.
