I'll do my best...
It's Windows XP Pro v.2002 SP3, AMD Athlon 64 Processor 3500+, 997 MHz, 512 MB RAM.
It's probably 4 or 5 years old.
I have several antiviruses. The main one is ShawSecure. I'm not sure how to get a detailed history report, but under statistics it says:
scanned files: 473,015
cleaned files: 12
programs allowed: 15
blocked from starting: 0
No emails scanned or filtered (I don't download email on this computer).
This was all since Nov. 30th 2009 when I last installed it. I just updated the virus definitions before the weekend.
The other antiviruses I have are Malwarebytes' Anti-Malware and SUPERAntiSpyware, both of which I leave off unless I need to use them. MBAM has a set of log files that I can zip and send to you if you think it's necessary. SAS, on the other hand, doesn't seem to have a history available (none that I can find at least). Both, like ShawSecure, have been updated just before the weekend.
Hope that helps.
