Qhost is a trojan that advertises to the user of threats that supposedly reside on their computer. This is simply a ploy to get the user to purchase Qhost in order to remove spyware and other threats. Qhost is incapable of scanning your PC or detecting threats, but may affect the performance of your PC. It should be removed at once. To remove Qhost manually, you must kill all associated processes, then detect all related files and values so that they may be deleted. Manual removal is not advised due to the risk of damage to your PC. To remove Qhost automatically, it is suggested that you use a legitimate antispyware application such as Spyzooka, which is intended for this purpose.
