virus? or malware?
Hi all, am experiencing something strange. Got a message that said I have three viruses and should immediately fix them. I did not click on anything or buy anything. But have since found some of my emails show up as just a bunch of question marks ????????????? And some of my files the same, also if I right click anywhere on this page or others, the pop up opens which should normally show open in new tab, or cut or copy or paste etc. Just shows lines of question marks. See screenshot below. Please advise what I should do. I did download the malware app which was suggested on this page. It removed one threat. But has not cured this problem.
