For an anti-malware program, I'm using SUPERAntiSpyware. I had been satisfied with it until recently...I'm not sure if it's doing its job. For example, when the scan in running and at the beginning of the scan it seems to be scanning suspicious files (i.e. C:\Program Files\Surf Sidekick 3) but it isn't saying it is a threat and I can't even find this file on my computer; also I have used other anti-malware programs and they don't seem to find or run across suspicious files. It doesn't help that lately I've been seeing videos and reading about how SUPERAntiSpyware isn't picking up infections compared to other anti-malware programs.
Here's the thing - I've used Malwarebytes and have heard that it's great. However I have had problems running them on both of my computers. The one has a hard time loading if I leave Malwarebytes installed on it, so I can't leave it installed on there. The other one I have, the last two times I've used it, something goes wrong (I haven't seen it, but all I know is that the computer restarts itself and I'm told that it didn't shut down normally and creates a dump file). So I haven't been wanting to use Malwarebytes.
Are there any other good anti-malware programs (preferably free) out there other than these two that would be good for a regular basis?
