, previously owned by GFI, is now developed by ThreatTrack Security Inc. but it was originally introduced in May 2010 by Sunbelt Counterspy...one of the early pioneers in anti-spyware protection with an outstanding reputation for years. Counterspy was officially discontinued a year later and customers were offered the option to switch to VIPRE Anti-virus supported by GFI.
I have never personally used VIPRE. I have read it that it's blocking of malicious downloads was only adequate and that it's zero-day malware
detection was below average. Generally if you're dealing with zero-day malware it's unlikely most anti-virus testing is going to detect anything since it takes time for new malware to be reported, samples collected, analyzed, and tested by anti-virus researchers before they can add a new threat to database definitions. The researchers at ThreatTrack Security need to show some improvement in these areas.
