my pc is really infected,i tried to download many antiviruses but without any chance to clean my pc because of invalid License,i aslo tried to reinstall new windows but it still running very slow so i made sure that it's still infected.
Now i am using the Free Edition of SuperAntispywares(Freeware),No need for License or codes,after scanning it detected 4 Trojans and many Adwares .(now my pc running very smooth)
u may Download it here < Download SuperAntiSpyware 5.0.1146 - FileHippo.com >
