Hi,

what exactly do you mean by “account program” ?
why can’t you restore it from the chest ? what happesn/any error messages ?

try to find info on where it originally belonged to, by searching avast reports/logs/WIN’s event-log

try repairing avast via control panel → Software → uninstal avast → repair

which virus name was given by avast (see report etc…) ?

scan the file with Online scanners from Trend (see below) & www.kaspersky.com ; pause avast shield for this
