Updating mcafee virus scanner
The programs tested were subjected to 1,274,928 instances of malicious code collected between Apr 04-Apr 08.
The reason: any malware collected prior to this is considered fairly well known by now* Note: no free version of these offered. The data seems to show that overall the detection rates are very similar (the differences are unlikely to be meaningful), with the exception of AVG which has a somewhat lower rate of detection than the others.2.
Also, as of this writing the newer version of Antivir includes an antispyware component.The choice of programs: Antivir, Avast and AVG are the most used and most well known freeware antivirus programs, and I use or have used all three for long periods of time.They are also most likely the top three best freeware antivirus programs.The programs tested were subjected to 45,831 “new” instances of malicious code collected between Aug 4th-31st 2008 (4 weeks in total).The results above seem to show that when handling yet unknown threats (malicious code that is so brand new that it has not been added to the program’s database), Antivir and Kaspersky have an advantage over the others.3.
