I already paid for an antivirus called ESET NOD32 and it cleaned out some things but my computer doesnt show the background, only when im starting or shuting down the computer. I cant play videos or else it freezes. I dont want to completely restart the computer because i have itunes and its full of my music and i dont want to delete them. I need help is there anyway i can find them and delete em? my antivirus has a quarantine thing and i dont know what it means its full of viruses its found.. do i click delete? or just leave it..i need help alot!!!!
