Hi,
is your avast uptodate ?
- Please mail any files not detected by uptodate avast to:
virus at asw dot cz
best put them in a passwort-protected zip-file; including the password and a system/problem description in the mailtext…
- loads of malware there: if you have important/sensitive data on your PC, or use it for online-banking, ebay or other privacy critical stuff:
backup your data, format, and reinstall Windows XP, securing it better this time…
otherwise:
maybe test the file with OnlineScanners e.g. from KAV (see below) to get some more specific names
(you need to temporarily disable AV-Resident Shields/Monitors to be able to scan the file online)
-remove the Virus/Malware and it’s system modifications according to VirusInfos from Avast, VGREP, TrendMicro, Kaspersky; you might also try searching for the virus name or filename with google
general removal procedure:
- disable system restore on Win ME/XP
- kill respective Backdoor/Trojan process with task manager
- search for the file/process names in the registry; remove the malware’s startup entries in the registry
- disinfect or (if disinfection is not possible) delete the file; this may be possible only after a reboot
-Secure your system (change passwords, secure shares, install patches/updates for WIN, IE etc…)
-scan your whole system with updated avast and maybe a 2nd scanner ,e.g. RAV to check whether your PC is clean 
-reenable system restore on Win ME/XP
