Firefox rules...
Hi all,
msconfig will let you see what services are loaded at startup, whereas hijackthis (highly recommended if you use Internet Explorer) shows you a list of programs or 'add-ons' to IE, for example toolbars like Google or Yahoo, and things which are outside of the usual installation, allowing you to see all the little bits of crap that have infected your IE setup.
For example, on my PC here at work it is telling me that I have Roboform installed as a BHO (Browser Help Object, which is the way viruses get into IE a lot of the time) but that's ok as I installed it. It's also telling me what loads at startup (BBC Ticker, HotSync, Office) and the extra menu items in IE (which are Roboform commands).
As mentioned above, the best way to use HijackThis if you're not sure what the entries mean is to run the file, and google for the entry as there's a few places where people post the answers
Best thing to do is NOT to install any toolbars, search assistants etc and to use Firefox instead of IE
Any specifics, post and I'll try and find more details for you.
Hope that helps,
-TPO.
