Could this be a virus?

I have a quicken program. All of a sudden it stopped working I go to get into it and it tells me I am missing a main file to run it, so I tried uninstalling it but it wont uninstall. I then tried to put the CD in to repair it but it wont repair it either. I also go into the hard drive to try and find the backup files but there is nothing there. I have also tried restoring my computer to before this all happened. Could this be a virus? Or what is going on?

when u put the cd in, dont do a repair. use the cd to reinstall the program so it will refresh the files. repair usually never works. also see if the cd will allow you to uinstall the program, and then reinstall the program.

download the missing file from the internet, and put it in the folder for the quicken program.

Sometimes your computer moves files... called fragmenting... this could be a possibility... try going to your disk defragmenter... (should be done every few weeks anyways) do a search on your computer for disk defrag... and the first thing that will pop up is the "tool" that allows you to de-frag your computer.. when you open it you will see a list of your drives... ie C: -this is your main drive (maybe your only one) click once on it or until it is highlighted than click analyze a box will come up with "you should defragment or not" just click close... now if you see a lot of red or if the popup said you should defrag than when you have some time to not use the computer (other wise it is super slow) click on defragment. This will get rid of most or all of the red.. the red is bad.. that means your files ar not exactly where or how they are meant to be...
