AV-Comparatives are one of the premier testing labs for anti-malware software. Every computer user owes it to themselves to peruse their site whenever they are about to choose, renew or purchase security software.
It seems almost every site is corrupt with bribe money from AV companies.
As far as I can tell, this is one of the few exceptions.
This site keeps it concise and easy to read, without omitting the important information like how they got their results.
Very informative website which conducts tests on several different Anti-Virus programs against the latest threats to see how well they've pulled against each individual anti-virus suite.
