To blast the misconception that freeware antivirus is not equally talented at recognizing malware as paid products, we grabbed five antivirus solutions for comparison and threw them in the ring with
16,704 malware samples (trojans, backdoors, exploits, spyware, worms, etc.). The purpose of the test was not to reveal detection differences between the free and paid product from the same company, but compare a free product from one company with a paid product of another.
In the freeware corner, there was
Microsoft’s Security Essentials and
Avira’s AntiVir Personal (
version 9, as the test was conducted before version 10 came out). Paid products included
Kaspersky Anti-Virus 2010 and
ESET’s NOD 32 at first. The fifth product included has a little of both worlds:
avast! Pro Antivirus 5.0 brings script shield and sandbox capabilities to the table on top of the features included in the free version.
