PLEASE help me UN-*** My Computer

Yep - PLEASE PLEASE PLEASE help me un-eff my computer!

It all started when I left my computer open and my retarded brother (YES IT WAS HIM and I'm sharpened a knife ready to strike him down) visited some site........

Then boom... tazebama.dll_ was the issue - some worm....

So... my attempts:
-AVG Free - did not detect it
-Ad-Aware - the moment I tried to delete it/remove it... the program would abruptly shut down
-SUPERantispyware - did not detect it
-Trend Micro virus scan - could not clean it

So I got McAfee - and it found around 1830 of it and cleaned/deleted it


So I thought that was it... but then I realized my computer was SUPER slow... so slow that my 10 year old computer functions faster AND I can't even attach a file in my e-mail 'cause it freezes (instead of it being a 5kb file... it freezes like I'm trying to select some 20 GB file)

So... I tried:
Re-check virus scan with McAfee - nothing there
Defragmented my computer... still the same speed
Disk error check (the right click on the "C" drive one)... still the same speed

I noticed in task manager under processes there are a LOT of ".exe" files that never existed before!!!

My startup programs (start -> run -> msconfig -> startup) have NOTHING selected... yet the computer starts of with TONS of .exe files in the processes of task manager


HELP ME FIX THIS! I have NO idea what to do anymore >....< I'm a computer newbie... so if you suggest something plz explain it a bit

Thanks

Jam it back in, in the dark.

Fine I recovered my computer

Now my new computer has tazebama.dll_ in task manager... so I wanna fix it before "bad" stuff happens... but I'm not sure I wanna try Mcfee virus scan anymore...

Any suggestions on what to use? 'Cause this computer literarly speaking died on me and I couldn't open the computer no more - so no backup yay!

Oh and PLEASE don't say "just use a virus scan" but as I listed up top (first post) - I TRIED! I need a GOOD one that will not destroy my other computer in the process of "cleaning" the worm out

There's nowhere I can't reach.
