What To Do When Your Computer Gets A Virus

For me personally, the last time I had a computer infected that caused irreparable damage was in the summer of 2001. My computer was running Windows ME . I received a Word document as an attachment in Outlook Express, but it turned out to be a booby-trapped W32 virus. Not even Norton, which I had installed and updated could remove it. All I saw was a red screen with no options. Ultimately, I ended up performing a factory recovery using the Windows 98 SE disc that came with the system. In 2017, drastic steps like that might not be necessary.
