Sounds like you need someone over there who knows what they are doing.
What you need to understand is that if you want something to be fixed, it will take effort or at least someone who’s experienced. You can’t say “I want help” but “I don’t want to do this or that”. Viruses cause problems for everyone, such is why they are a pain. It’s not a pleasant experience and it’s not going to be fixed by snapping your fingers; you have to take certain steps. If you don’t want to spend hours on it, find someone who can do it faster.
As far as running a virus scan: Open or install an antivirus program and run it. It’s pretty easy. There are free programs out there (AVG free for instance) and plenty of information on the net about what to do; you just gotta spend some time googling, installing, etc.
