Probabily not, coz they are both trojans, I think is easy to kill them.
You should instal a good firewall,antivirus,antispyware,pop killer,spam fileter and so on. I think you should have zone alarm security suite,coz this package is the best in market and have, It have the best firewall in my opinion(with test results comprove by me), a great antivirus,a excelent popkiller and spyaware remover. You also should conisder kaspersky or avg,coz they are also great antivirus. Althouth because of conflits and lower speed of you pc use only one antivirus. Don't think of use norton antivirus coz it's a very poor antivirus and "eat" many ram.You also should do updates to your windows if you have this S.O.
