Yikes, that's a pretty awfull software, you would be better off cleaning your PC with Ccleaner slim...free...and fully functional.
"I installed antivirus "quickheal". "
What the heck is that???
I would uninstall that pretty fast and try Avast Free, install it and get Avast to do a bootscan on reboot and put all it finds in the chest.
You may want to try all these other free progs too for starters
1- trojan remover
2- hitman Pro
Run them all untill they are clean.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
