Scaned system twice

I just got avast home and ran a thorough scan and it did a full scan of my c drive but it seems that it started to scan all over again what it did before so I just stoped it. Any idea why it doing this? Hope Im explaining prob Ok if not ask any questions. Thank

Kodiak,

What do you mean by “it appeared to start over”?

Was it scanning the C drive or Memory?

Did you set Avast to scan any other drive that is internal, floppy or CD?

Thanks
