I have been using McAfee which came preinstalled on my laptop (I neither like my brand of laptop nor the av it came with).
I scanned my pc with quick and full scans and it returned 0 virus/mware results.
I knew I had a virus/mware or something because of unnecessary hardware usage.
I downloaded Microsoft Safety Scanner (free) and Gridinsoft. Needles to say they both picked up the viruses/mwares that McAfee had not and still can not.
Personally I will never use McAfee again.
Side note: The customer service at McAfee is slow and difficult to contact. They don’t reply to emails or messages. And all the while my pc was infected…
I transferred only my work docs to a cloud service and I’m going to send my pc to experts to get wiped. I’ll run my work docs through Google’s virus checker before downloading onto my pc again.
Any other tips are welcome.
