G2S-archysw-cs.com G2S-archysw-cs.com Forced me to buy thier protection software , Internet

This company somehow made it impossible for me to launch my Norton and forced me to purchase this software instead.  I'm no computer whiz and I did try everything I could think of to get around paying for this G2S-archysw-cs.com.Even updated my Norton and paid for that before the renewal date (just 10 days before the renewel date).  I couldn't down load Norton and ended up getting a refund from them and like a FOOL I purchased this software.  It did work for about 1 week. Now I cant use anything on my computer at all.. Internet wont even work. Now Explorer is telling me to purchase some other software to get rid of the 30 virus' I now have on my computer.  At this point I feel like tossing out the HD and just buy a new one.  what a rip off and a waste of 60.00 !
