Hi, i ran spybot and it said that it fixed my problems but i don't think that it did because hijackthis reports ISEARCh lines and the installer file is still in my windows/downloaded files/ directory. Please tell me how to get rid of this! Here's my HJT log:

Hi . Unzip HJT into it's own permanent folder before doing anything in order for it to create backups. (Not a temporary folder & not on the desktop). Close all (browser) windows & have HJT fix these entries by placing a check in the appropriate box=

Reboot. Should now be sweet.

THANK YOU thank you I just did that and now hopefully it'll all be good... I suppose I can delete the isearch file from my windows/downloaded programs folder? And how did this get on my computer in the first place?!?! anyways i really appreciate your help.

Check out the "So how did I get infected to start with..." thread here.
And you can delete that folder & anything else you find related to isearch.
You are very welcome.
