I recently was hit with a malware and I removed my drive and scanned it and just to be sure, I downloaded and installed malwarebytes and scanned as well. Whatever was on the pc has been removed as I have scanned numerous times with MB and Hitman Pro. All come back clean.
However, I am not able to download attachments from emails or files from websites. So I think I still have a virus or malware left on my pc. The attached screen shot shows what I'm getting when I try to download a file from Gmail.
