Help!!! Something I Wrong With My Computer But I Don’t Know How To Fix It!?

well first of all I used to download Also of Sims 2 tuff, but After a while Every time I would try to open something it would ask: open with, and a few things to choose from. Only one seemed to actually work for something, and that was the Internet explorer. But after a while longer, every time I would open Internet it would take me strait to click-freeze.com and say it could not open the web page, even though the little computer icon at the bottom sad internet access was local and internet! I’m not sure when I downloaded click-freeze or why, but when I found it in the control panel and tried to uninstall it the open with thing comes up and there is no icon that works with it! So I cannot uninstall it! I deleted Every thing I downloaded for the sims 2 already and the open with page is Still there and I am trying to uninstall al my sims 2 games but the same thing happens when I try to uninstall them to!!! I sm so frustrated right now, and I am not experienced very much at all with computers! My family is not really willing to pay for someone to try and fix it. I suppose I could try and persuade them to, but f someone could help me get rid of this issue I wouldn’t need to. If I didn’t mae to question clear I’m sorry. And I am actually on my phone right now not on my computer. The laptops work just fine also and I’m Pretty sure we all share the same internet. We use embarqmail. And out computer is COMPAQ WF1907 and we use allot of windows stuff. Our virus Scanner says we have no viruses. PLEASE HELP!!!!
