I think you are in the wrong forum - if you believe that your computer is infected, you should post this in the section 'Am I infected ?'.
However, you say that you have run several anti-virus and anti-malware programs which have told you that you have 2000+ infections. This number is unlikely, and you don't say what programs you have been running.
Go to this URl and download and save the installer to your desktop, then double-click on the icon and follow the instructions.
When it has installed and updated itself, run a 'Quick scan'. If you do have any nasties on your computer this will detect and fix most if not all of them. If this sorts your problem, well and good. If it doesn't, post this request in the correct section of Bleeping Computer and wait for more expert and specialist help, but list the programs you have run.
PS - Malwarebytes has two things going for it. First, it works very well, second, it's free !
