About 2 or 3 times out of 5 searches, I am redirected to a scour site.

Additionally, three Days ago McAfee found a virus [Generic.dx!ttw]; Windows defender called it [Win32/Opachki.D]. Though both claim to have fixed it, I'm not certain. Yet I have not seen any more indications via scans and have run multiple McAfee and a few Windows Defender all ending without finding anything.

Following is the Hijack scan log:
