Having AGV 7.5 and Spybot enought?antivirus programs

Part 1 to your question) I would say it wasn't. But then again, you can never have "enough" if you know what I'm saying. The programs I use include the following. Notice how there are 2 or 3 of the different programs with the same purpose. This increases your likeliness to remove/detect a virus.

AVG AntiSpyware

Etrust Ez Armor AntiVirus

Bit Defender-Free Edition

A-Sqared Free

A-Sqaured StartCenter

Ad-Aware SE Personal

Trend Micro- Anti Spyware

Microsoft Malicious Softawre Removal

Spybot Search %26 Destroy

eTrust Pest Patrol (only "detects" the infection unless you buy)

Windows Defender ...and..

eTrust internet Suite

As much as these are tons and tons of programs (they are @ apprx. 10-20 Mb. each) I unfortunatly STILL don't detect all viruses. Although, I am well-protected. Also, when choosing programs, I highly suggest that you make sure its a known name. Especially with Anti-Spyware products. Those especcialy contain viruses. So, Make sure its a Corp. not some random name, like Super AntiSpyware (which is a program) which i DO NOT reccomend buying/using.
