Some recurring infections could be solved with a boot-time scanning:
Start avast! > Right click the skin > Schedule a boot-time scanning
Select for scanning archives.
Boot.
You need XP or 2k to run it.
Other option is scanning in SafeMode (repeatedly press F8 while booting). Other is disabling System Restore, boot, enable it again.
