I believe I may have some Malware on my desktop computer. My desktop icons and everything in my Start section do not respond. When I click on any icon I get a box that pops up saying, "Choose the program you want to use to open this file." I have no idea what to do. Whenever I try and run any program it tells me I have to do so with a certain program. I did not have this issue last night, but have today since I ran a Norton's virus scan last night and closed down my computer. I had been getting a constant pop-up that looked like a Windows element, asking me to download something with "2010" in the title. I didn't do it, but somehow it's on here. Any help? Thank you.
