My laptop has been freezing lately so I tried to run a SuperAntiSpyware scan but it restarts during it so I am stuck what to do. I have completed Avast and Malwarebytes scans and have not found anything. Oddly, the Firefox tabs' borders I have open seem to have a slight transparent look to them. Might be nothing to do with my problems but does seem odd.
You can certainly run an online scan. Seeing your link still makes me think it could be a connection/hardware problem somewhere and just a coincidence that scanning with SAS was the problem. Why not uninstall SAS, reboot, and see if it occurs again. Should be no problem as you still have Malwarebytes installed.
