Hijackthis :?
Very good, but can be dangerous to someone who doesn't know how to use it.
VSMIT.
Congrats. You just described every good, powerful tool for diagnosing and fixing software problems.
i think its good cause it finds stuff that iv never seen and my other things never found
It depends on what you're trying to find. Hijackthis is good at what it does, but it only finds internet explorer hijacks. My bet is, if you're IE is hijacked, you probably have other wares that you'll want to get rid of. For my customers i usually use it in combination with other software cleaning tools.
i have never used IE on this PC, only firefox and it still found bad things
Dad uses it, and hes one of the people that if he uses it its good. So yes i guess i recommend it.
