If you have not already tried MalwareBytes to find and fix system changes a virus might have done to your computer, please try that first.
If you have already scanned AND cleaned your system using Malwarebytes and the problem persists, I have created a Boot CD utility that may allow for detection of rootkits or manual system repair. I suggest you scan your system with ESET and McAfee from the boot CD and report the findings of all of the scanners, including the previous MalwareBytes report.
