I have a keylogger on my computer and Norton 2009 cannot detect/find it.
I know I have a keylogger because my World of Warcraft account had been hacked via it. Yet I can do a full system scan for the 5th time -- with updated detection library ofc -- and Norton still cannot find the keylogger.
This was the first year I decided to replace AVG with Norton. And within 2.5 months I have a serious security breech that Norton still can't even detect after the fact.
