something called vista internet security downloaded itself onto my laptop recently and is blocking me from using most things on my computer. I really need help here because i can barely get the internet working long enough to post something like this. if anyone has dealt with this before please tell me how to get rid of it. I know this program is fake because it has a few things that just aren't Microsoft about it. this damned thing won't let me execute to many files either and every few minutes it hijacks firefox and internet explorer and tells me that sites like google and yahoo are unsafe and virus laden. this thing sometimes say vista internet security 2010 on it and it keeps popping up. it also keeps saying i need to give it my credit card info (how blatant can these people get)the pop ups aren't in microsofts style of security. so please help me.
