Thanks for all your help and work you people put into this site helping people with their computing problems. I recently had many malware and trojans on my computer and followed your guide to removing them and so far avg and malwarebytes say my computer is clean. So next i followed your advice and preventing malware and trojans by getting rid of IE 7 and downloading firefox 3 with the addons you recommended. But after i removed ie 7 i had to reboot and then i could not load explorer.exe because iertutil.dll was missing and windows would stop loading. So i fixed that by opening task manager and running firefox and downloading a new iertutil.dll from a trusted site and put it in system32 folder and all was good after that except now i cannot download anything because there is some type of glitch where you can not uninstall ie7 after installing service pack 3. I went to follow mozillas advice on the situation but i cannot open my internet properties from control panel because it says "Ordinal 56 could not be located in the dynamic link library iertutil.dll". Sorry for such a long post but hopefully you all can help me out.
