Yesterday I clicked on a site, and then I had Win32/DownloadGuide.F virus on my computer. I’ve been spending my morning searching all around to get answers of how to get rid of it but still nothing worked. I scanned the computer with several antivirus programs like AVG, Norton and Malwarebyte. After I removed a few malicious items they found, the virus was still there and won’t go away. I’m so frustrated & annoyed!!! Any clue as to why this could be happening? Why antivirus programs cannot get rid of it? How do I delete the virus completely?
