Thanks for your reply. It is the restore icon that is grey so I can’t use it.

I have sent about 8 emails to Avast and had no reply since the first one.

Extract files icon works but I know little about computers and am not sure what to do.

Thanks Leslie

PS I don’t snow if relevant, but my spy checking software AVG says I also have Back Door Agent BA and JAVA_BYTEVER A-1viruses that I cannot remove.
