One more thing I'd like to mention here:
I had to format my hard drive 3-4 days ago... did a clean install of XP Home SP1... then avast home edition with latest definations... then installed XP SP2... since then avast has been tracking so many different viruses, trojans, malware, etc... which is really weird... I mean, first of all OS is freshly installed and I hardly sat on the internet, and it caught 3 viruses yesterday, before tht it caught like 3 infected files while performing a boot scan, and even today, I ran boot scan and it came up with 3 newly infected files. I dunno, what's going on, but I've deleted all those files.
The real concern for me right now is, how come my system got infected with so many viruses like tht in like 2-3 days of OS installation... and I hardly logged on to the internet other than downloading SP2. Sounds fishy, NO?
