The Virus Cleaner does not use the VPS file. It is a completely standalone tool - when you download it from web, you can run it on any computer you need (there doesn’t have to be avast! installed there).

A special version of the Virus Cleaner is placed inside the VPS file - and avast! itself knows how to call it if needed (i.e. if a virus is found that the Cleaner is able to “handle” better than avast! itself). But still - even this Cleaner does not use any data from the VPS (it knows everything it needs :))
