Hi Negeltu !be carefull by using avast! & Antivir together.
I think you're SUR-protected .You aught to ask opinion others guys (Bob,Eddy,Technical....) It is possible that such a plethoric protection is dangerous.too much may be too bad!
No need to worry.
Antivir could be used as a backup scanner (not resident) and works with avast! as the on-access (primary) scanner.
Just be careful, some 'macro viruses' discovered by AntiVir are just false positives

Runnind an on-demand with AntiVir does not require to shut down avast! Standard Shield provider, at least, not necessarily
