After experiencing 'detection failure' over the years with AVG,McAfee & Nortons I found spydoctor from pc tools to be the only reliable option. I discovered this after being strongly suspicious of viral action on a desktop. All of the above failed to detect any virus. I installed Spy Doctor. Bingo, it detected several virus's and cleaned them. Symptoms instantly rectified!
Used it for some 5 years now without a sniff of any viral symptoms and many many infections detected and cleaned.
Give it a go, I think you will be surprised at the results.....
