Recently, my computer has been infected with Virtumonde again (this is my 2nd time being infected w/ this). I get random pop-ups occasionally when I'm on the internet. So far I scanned my comp w/ spybot and it detected virtumonde. I also tried to scan my computer with my comodo (my anti-virus software that I had for 2 years) and it identified 6 threats; however, I couldn't finish the scan since it lagged half way. My comodo never finishes its scan b.c of the harsh lag which may be why it takes forever to finish. Lastly, I tried to scan my comp w/ malwarebytes software but it wouldn't run b.c some files were missing (idk why...). So I tried to re-install the software but the same problem happened (files were missing). I tried to find similar threads that may help resolve my problem, but most threads involve malwarebytes software which doesn't work for me anymore.
Help would be greatly appreciated and would make my like so much better
