I was using NOD32 Enterprise but overtime it just became slow and caused numerous conflicts with business software we use.
Since then I've been on Sunbelt Softwares beta team for their new Vipre Antivirus / Anti-spyware. I was using their Counterspy anti-malware program and was very happy with it. It was a highly modified version of Giant Softwares malware engine, the company Microsoft bought for their own anti-malware solution.
Vipre is a completely new tech (released just this last week) built from the ground up to combine anti-virus and anti-malware in one system.
Seems to be working good so far.
Which software did NOD32 conflict with?
F-Secure
I have it installed on all of our 200 workstations at work, becourse we got a great deal on the whole F-secure range through our provider. Of course I nicked a copy for myself. Works great, but thend to slowdown startup more than other AV products I know of.
Recently started working for Circuit City's firedog as a tech, and have been doing a lot of antivirus work. One day, I got to thinking, what do TWers use for their AV software? Maybe I'll find something that our higher ups don't know about and I can suggest we start using it.
Me personally, I'm using spyware doctor, works great.
