Justsweet,
You have downloaded Eanthology at some point, this is spyware/adware/trojan masquerading as a virus scanner and other things. It really makes a mess of PCs. You also have IEFEATURES crap, as well as your browser has been hijacked by SEARCHCENTRIX
Download SPYBOT S&D from this link:-
http://www.safer-networking.org/index.php?page=download
Make sure you update SPYBOT as soon as you have installed it, you can download the updates listed in the same link above, DETECTION and TOOLS. To install those, run SPYBOT ONCE, do the IMMUNIZE thing in SpyBot, then CLOSE the program. NOw click on the DETECTION update and let it install, then the TOOLS update and let that install.
Open Spybot again, and IMMUNIZE again. Also now install the BROWSER HELPER below the Immunize.
Finally, you can now CHECK for PROBLEMS and let Spybot find Eanthology and others and clean all that it finds.
Now you have to go into ADD/REMOVE and remove all instances of Eanthology.
Reboot and use Hijackthis again. From the scan list, check the following lines if still listed:-

hit FIX CHECKED, reboot again and see if things look better. This may not be the end of things, but it's a start. Get back to the forum after you have done all of the above, and we'll see what is left. Some of these insidious programs can hide themselves and pop back in again.
Safe Computing...:o)
