That’s my thought. I don’t doubt this fine Freeper really got a malware infection somehow, I just believe they’re mistaken about how it happened. Even if they didn’t do anything stupid or careless, someone else certainly could have on the machine.
Malware Bytes is good stuff, tho...I tend to check things over every day or so with it anyway.
Is the Malwarebytes compatible with anti-virus and firewall software?
