Ok, when I boot up it SEEMS fine, except all my programs have the Microsoft Word icon on them... and my computer attempts to open them in Microsoft Word (which is my word processor!!!) Things NOT affected are the Recycle bin, my network places, Internet Explorer and an Apple Application (as in apple computers). I can run a FEW things if I go through a long process of finding out the command to run it in RUN. For example, I can run ad-aware by typing ad-Aware.exe into run, then clicking select program from list, and then going to the file where it's located, click on the file, which then adds it to the list and then I click on that! and it will run But I have to do that EVERY time. So far that has only worked for adaware, and Yahoo Messenger, It pulled up Symantec Antivirus, but it had troubles scanning. I attempted to do what Sabu suggested in safe mode, and I had to go through the whole scenario that I described above to even get into it! When I finally click on the System Restore icon I get this error message- C:\WINDOWS\system32\Restore\rstrui.exe is not a valid win32 application
