My computer was getting slower and slower - sticky keys when typing in documents or online, browser freezing, etc., and I was even experiencing my cursor behaving so strangely, it seemed at times it was being operated remotely. Scans with avast (paid version) and Malwarebytes (free) caught nothing and there was no improvement, so I used mbam-chameleon and did get a "killing known malicious processes" message. I completed the scan and my computer worked fine again, but only so long as I only put it to sleep. If it hibernates or restarts, the problem returns. On returning to use mbam chameleon again, one version wouldn't open, another opened but couldn't be updated (message on the DOS screen highlighted in red), etc. It took a few tries to get it to work, and every time the "killing known malicious processes" message is there again.
I'm running Windows 10 64-bit.
I've got a major concern now, too, about ransomware, but I'll have to start that in another topic).
Thanks so much for your help.
