I'm using a combination of Microsoft Security Essentials and Avast freebie.

I contacted McAfee about some abnormalities with browsing and their rep said if I had an infection they would help me recover them otherwise they were not interested. I dumped McAfee on this machine before the free, bundled installation ended and never used it on the other machine. Kaspersky is another very good security suite. Windows 8.1 on 2 computers, Firefox with bluhell firewall, ASC, Norton. ASC is available in both free and paid versions at, worth having. I still use Malware Fighter as it is combined with Advanced System Care which does a very good job of keeping the registry clean and defragmented, junk files cleared, and similar tasks. I switched to Norton as it was on sale just before the first of the year and can be installed on 5 devices. I was running Comodo internet security suite, free version, for years and contracted two viruses recently that it did not detect nor did Advanced System Care Malware Fighter free version.
