Computer keeps opening up different windows and programs by its self!?

Maaann my computer has been acting up ever since I uninstalled Google Chrome I took it to a computer repair shop they told me it has a virus and the other problem is that it doesn't have a genuine copy of Windows 7 that uninstalling Google Chrome has nothing to do with the issues I'm having but due to being on a very fixed income I can't afford the price they want to fix my computer. I'm not exactly sure on how I could of gotten a virus I have Norton 360 for my antivirus I was told this was one of the best? Can someone please tell me how to fix these issues PLEASE

Thank You

It appears that the installation has yet to be activated. Do you have a product key to do that? It should be on a sticker stuck to the sleeve that the Windows 7 installation DVD came in.

Unfortunately no I d

Sorry about that last post as I was saying no I don't have the product key the computer was given to me and I have no way of getting it I also don't have the cd this computer came with. It originally came with Windows Vista can I take Windows 7 off and put Windows Vista back on? I do have the product code for that.... Thank God for the sticker on the bottom of the laptop!

Yes, you can reinstall Vista if you like, or even purchase an upgrade from Vista to Windows 7.

Oh ok how do i do that? And when i do that will it "wipe out" the whole computer including drivers and virus if thats what it has? Because the computer is doing strange things its almost like someone else has control of my laptop.

Yes, it will clean up all the bizarre behaviour.
