Error that widows cant find solution for and wont even open firefox

Question

earlier today firefox was working fine but now when i click it the only thing that happens is a pop up saying that firefox is not responding and that it must be closed and the same thing is now happeng with internet explorer so i cant even try to delete firefox and reinstall. the only thing i did between the time when it was working to when it stopped was delete some shortcuts to myspace messenger and yahoo messenger. my grandmother googled a few things to try like entering cmd on the start menu and running it as admin and entering ipconfig /flushds or smething like that and when that didnt work she had me do some cleanse thing that u have to restart the comp to do and the cleanse thing was in the area with the defrag but nothings working and i just dont know what to do. as is im filling all this out on my xbox 360 so srry about not putting capital letters and stuff. any help would be extremely welcomed and very appreciated

Answer 1

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
Do a malware check with some malware scanning programs on the Windows computer.<br>
Please scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.
