Reboot your computer, press the F8 key to start Windows in Safe Mode and perform a full system scan. If it still doesn't detect and remove all the viruses, you will need to uninstall the software and acquire another antivirus program. To completely remove the application from your computer, try using Revo Uninstaller. Even if it can't uninstall the software normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
