computer slowing down

on a windows xp computer at work, when we go to "start" and click "my computer" it takes a long time to open(more than 2min), after that Avast shows an alert: "Win32:Trojan-gen {Other}" after you click on delete, it opens "my computer"…but the problem occurs again the next time i click on "my computer"

anyway heres the hijack this log:
