I scanned my computer with microsoft security essentials and found 3 virus which includes svchost.exe
After removing virus when i open any .exe files or installed application I get the below error..

I tried to system restore @ earlier state but nothing happened, files are opening when I right click and run as administrator.
Even task manager is blocked
