Thereby bringing everything back to your immediate attention.
There are roughly "a million and a half" threads running rampant on these forums already with users comparing/contrasting his and her preferences, declaring which AV protection is superior over the other and so forth... They are lengthy and sometimes redundant reads however there is alot of good information within them if you take the time to search them out. You will get an idea of what is best suited for your needs.
So far as your system is concerned though... with having that many "nasties" (I like that wording) plaguing you, I would not even bother with removing anything. Reformat and start fresh. Odds are that your system is so far taken over by this stage, that for every one "nasty" you kill, five more will take their place. Find a suitable AV program. Reformat and reinstall your operating system, and then put that AV application in place while making certain that it is up-to-date weekly with the latest virus definitions.
Backing off on all the pr0n sites may also save you alittle grief as well... j/k. :D
