I was just looking through CCleaner's Uninstall section and I noticed a single entry for CVE-2013-3893 with no publisher or version number. It was installed on 5th October 2013, the same day I updated from Windows 8 Pro to Windows 8.1 Pro. What is this? Is it a virus (and, if so, then why would it leave an uninstall entry)? If it's a legit Windows application that why does it look so suspicious? I've ran both Windows Defender and Malwarebytes' Anti-Malware and neither report anything out of the ordinary. :3eyes: Do I have a virus or not?
