I was trying to see if removing any possible malware would fix the problem (blank desktop) but then i realized i would need to get to get rid of some programs first, like old antivirus programs, but I can't uninstall them without getting to the control panel. The only way i can get to things is using task manager

HP Pavilion a1110n
