The Anti-malware testing group AV-Comparatives.org tested sixteen products on the malware removal/cleaning capabilities of the security products installed on an already infected/compromised system.
The best performing free software by the Anti-malware testing group was Microsoft Security Essentials and they've also given it their best ranking in their performance test as well.
I have installed Microsoft Security Essentials and and have found it to be very fast and light on system resources. I compared it on a PC running XP Pro SP3 machine with AVG 9 Free edition with Spybot Search and Destroy. I have now removed AVG 9 Free edition and Spybot Search and Destroy and replaced it with Microsoft Security Essentials. The PC is running faster and has more free memory!
