Unlikely to be HijackThis, Jeri. That's a well-respected anti-malware program (I've used it several times to clear up other people's machines). The only problem with it is that it requires the user to be very knowledgeable about what it shows you. It points out things that may be symptomatic of virus or malware operation. Unfortunately the same behaviour may be there for quite legitimate reasons and the user has to be able to distinguish which is which before getting HijackThis to fix things. There are several forums where volunteers will look at HijackThis log files that users post there and will tell them what to do (eg TomCoyote, CasteCops).
