Gamerzplanet virus question.?

Around late october i decided to start hacking in soldierfront to combat all the dxting noobs.... so i went to gamerzplanet and downloaded Verminators hacks. Verminators seemed to be trusted to i thought i had nothing to worry about... so i downloaded a wallhack and other hacks. Then i noted he loged ips and created a program wizzard in which the hacks would be in. So after activating the hacks and trying them out.. i noticed my pc was slow... REALLY SLOW like major fps lag in every map... and major ping spike from 6 ping - 500 ping.....and with a 2.5 k xps system this never happened to me before and this lag happened right after i downloaded these hacks. Therefore immediatly pinpointed the problem to be the hacks and deleted them ( BIG MISTAKE). Sadly deleting them did not do anything and my pc was still fps lagging with major ping spikes. I called dell and purchased products after products to " COMBAT AND BRING MY PC BACK TO ORDER" and none of it worked... after 8 strait months of talking to dell and norton about this problem it seemed no 1 could fix it. Sadly my computer still hasnt been fully fixed.. i fps lag randomly and cant use fraps to record my gameplay but at least the ping spike is gone. This however is very bad due to me having dreams of actually being a very good player. The problem is my recoil on guns changes every time i shoot so therefore my computer was never fixed properly. IF ANYBODY CAN HELP DIAGNOSE THE PROBLEM OR HELP WITH A SOLUTION I WOULD BE HUGLY GRATEFUL, i reformated and defraged my hardrive numerous times and nothing seems to work... Plz help a fellow gamer :(
