Solved Default Programs

I had a virus a couple of weeks ago and had it removed, but since the removal my computer won't open up any programs without going through default programs. If I click an icon on my desktop default programs pops up and I have to find the right program to open the programs with. I was reading some other posts and saw one that suggested that I download PC Medkit, I did it and it did not work. So now I'm out $40 and my computer still isn't functioning properly. Any suggestions would be extremely helpful.

Just as I finished posting this, I reran the PC Medkit and it seemed to have worked this time.

If you run into problems, again, let us know.
