The PAV.SIG is a PC Pitstop file. You can find more info at pcpitstop.com. Norton will say it’s a virus. Apparently, so does Avast.
it is a false alarm
Sorry - I should have explained that, yes, it is a false alarm. The PC Pitstop file (PAV.SIG) is needed to be able to run some of the site’s tests. It’s not a virus.
you can submit the file to avast and mabye they can fix the false alarm in the next update
No, we will not fix this. It is clearly Panda’s fault and not only ours problem - the Virus Bulletin had an article about this last autumn as well (many products detect Panda’s files!). They clearly fell to do the rule number one in their product - that the strings have to be encrypted in AV products. The problem is that if we remove one false alarm, there will be another and so on

There’s a new item in the FAQ - I would suggest to check it.
I mentioned the Virus Bulletin article discussing this problem. You can find it online here - on the page 17…
