windows vista with bad virus antispyware soft

[bobbyg2208]

hi all & thanks in advance!
i've seen several post on this culprit (antispyware soft) using XP i have vista. i cannot go to any website. cant run system restore. nothing works. i cant download highjackthis or any program. i am using a small laptop to write this. (acer 10.1 netbook)  is there anything i can do except reload whole puter? 
in desperate need.

To clarify, when i open IE up and try to visit a website, It says "Application cannot be executed. The file.exe has been infected." THEN a tab (in IE) opens and goes to a website that trying to sell an Anti-Virus Software? i try & go to task master & it starts then dissapears with a warning of virus. then once i leave it alone for a min or 2 it opens ie with an ad for porn or a lil blue pill.
