i recently had the fake anti virus 2010 on my acer. i just got rid of it but theres still something wrong. i cant get into some of my files. for example, firefox. i clicked on the icon and the window popped up asking me which program i would like to use to run firefox. now i decided to just restore back to factory settings. so i went to control panel and got to the system restore option. i click on it and the same window pops up again asking me which program i want to use to run it. someone please help? i need this netbook for school and im in real trouble here. please and thank you.
