Uninstall a program showing wrong size

[enigmas]

So I have a new computer and everything was running fine. But the next day I open my "uninstall a program" and it's saying outlandish sizes of things. I have the game Oblivion and it's not saying there is a size while as Network Magic is 32.6 GB which is HUGELY wrong for it's only a couple of MB. I am not that good with computers so googling help got me confused with registrey key and stuff because I dont know how to access this. So, I restarted computer and everything but it's still wrong. Please help I don't know what to do or if this is dangerous

Is there anything wrong with performance of Win7 or the programs themselves?

Run SFC -SCANNOW Command, report back what it finds.

If it finds no OS corruption and you have no performance issues then I would not worry about it.
