Error code 42125

Hi all,
Can anyone tell me how I can remove this error as it has started to make my computer very slow.

Thanks for all your help it is very much appreciated

Where does the error message appear? Can you take a screen shot of the message?

What version of Avast are you using?

avast Error 42125 = ZIP archive is corrupted

Something you should only see when doing a scan , are you running a Boot time scan ?

Hi all,
