I was infected by win32 cryptor. My AVG flagged a warning and claimed to block it, but since then stuff has been going wrong with my computer. There are random pop-up ads even when there is no internet (the ads don't work if there's no internet). When the computer starts up, windows explorer will screw up (no specific message, Windows will just tell me that it's stopped working and restarts it). I ran AVG a few times and that found a few viruses (and removed them) but it didn't solve the problem.

I installed Malwarebytes (successfully) but it has difficulties working. Either it doesn't open when I click it, or it just shuts down (with no notice or error) if I try to run a scan. I renamed the .exe file and ran a scan. As Malwarebytes was scanning, AVG detected a lot of trojans and stuff and removed them. Malwarebytes only detected and removed 3 errors. However - one error needed a reboot, and when I allowed Malwarebytes to reboot, it just crashed and didn't reboot. However, I can see that file in the quarantine.

I just wanted to know if there's anythign else I need to do to purge cryptor from my computer. The pop-ups are still occuring.

And this morning when I turned on my computer, there was an error message that said "C:\ProgramData\hupetetu\hupetetu.dll" could not be found.
