My parents are having major issues with their computer and I was hoping someone cleverer than I could advise me how to help rid their pc of two particularly problematic viruses.
For info, the computer runs Windows XP, is fairly high-spec and it has AVG, Ad-Aware and StopZilla installed.
The problems started when my naive younger brother downloaded something for XBox Live which turned out to be a virus. It stole his MSN password and 24 hours later my parents credit card had £128 less on it as someone had used his details to hack into his Xbox account and spend all that money!
My younger brother then downloaded a program called 'MSN Password Recovery' (I know, but he is only 10 and has no common sense whatsoever)!
If I go the startup screen on msconfig there is a process called mscrss that I can't get rid of (although I have unclicked it). When I log into Windows a program called winudp.exe tries to run automatically. Finally, a program called zxx keeps being found and removed by StopZilla but each time I reboot the computer it comes back.
I have done online scans with Onecare and Trend Micro Housecall (and the latter removed several other pieces of damaging malware) but the three I mention above remain. Neither AVG, As-aware or StopZilla seem to recognise them as viruses.
Can anyone help me out on this? I'm at the end of my tether.
