Dear all first time post from anot too computer savvy user.
I think my laptop is infected with a virus or something similar. All of my file extemsions have been altered to end in .725 ie myfile.txt..725 and I now cant open any of my files. Have done a full MacAffee scan and found nothing.
If I create a new file in excel it saves and reopens without any issue.
My browsers ( edge and firefox) have had all favourites removed and some of my programs have gone back to their default settings from 2 years ago
Any help pr advice appreciated
