I have a windows 64 bit labtop.... the antivirus program that came with it is norton... so i bought the internet security program. But i have not been able to use it... it slows my computer to a crawl... and the only way i can fix the problem is to do a complete system restore... its funny my subscription expires in a month or two .... but i'd at least like to try it for that month or two can anyone help?
