So last night I got a virus on my computer, and it seems to be affecting firefox over anything, It opens up a new tab every 5-10 min for an ad to different websites. I have BitDefender and Adaware, both pick up the virus's and say they've deleted them, yet these adds keep coming back. My computer had been cleaned to the point where both say there's no virus, and i've uninstalled and reinstalled firefox... and advise?

Try to Roll back your system to before you went on a porn site and got this virus

I had one last week and it was ****ing up my firefox sending me everywhere, i restarted my system it said it was clean but it was still being a pain in the browser, so i rolled back a few days, and its fine now
