Hello; I am using Windows XP. I got a virus "Warning 26 viruses found your PC may be infected." I went to the internet and downloaded several virus removal tools. My PC will not let me do ctrl alt delete. I tried several keyboards but the same thing happens. When I try to install the software, the hour glass comes up for 1 sec and just dissapears. No matter what I do I can not install any software or go to the task manager to stop the processes. I even tried in safe mode with no success. Please Help!!!!
