So my computer has been acting up alot lately from having error messages pop up when I first start the computer to it just shutting down on its own sometimes. I know I have a vundo virus or something and used a program to try and remove it but it didnt work. I also have avg and it still wont fix the problem. It is a sony vaio that is about 3 or 4 years old and has only about 3 gb of space left on the hd. I asked my friend who is pretty good with computers to help and he said the best thing to do is just save on my separate HD the files I need and delete everything else but how exactly would I go about doing this or should I do something else? Im not sure where the disks are that came with them but maybe I could find them. Any ideas for what I should do? New computer in my midst?
