I have a Dell Inspirion 5030 which I purchased about 6 months ago. About two weeks ago, a virus invaded my computer (the virus was one that continually said that you need to purchase some type of virus protection software). At any rate, with the virus I could not open internet explorer. I've since had the virus removed from my computer. However, now I cannot connect to my wireless network. I am running Windows 7 on my computer. Windows can detect the wireless network but cannot it will not connect. Can you please help me. I've trying everything that I know to do.
