please don't think i'm being cruel, Alicia, but you're really hanging it out there, aren't you? No SP2, no active AV; are you at least using window's firewall? [i cannot tell..].... bug writers are looking for you right now. When this is over, go get AVG Free antivirus 7.5 [it is free..], and ZoneAlarm firewall [free too]. Both are good, but there are others too.At the least turn on windows firewall. Further, Isearch is loaded in by ActiveX control, so i suspect that your internet security setting could be low? It should be Medium, at least, imo.
Now for a start, please move HT off your desktop - i suggest placing it in a new folder alongside your program files. There are valid reasons for doing this... so if you still have the HT zip delete the desktop copy and unzip a fresh one, otherwise download a new one.
I am looking for a file named toolbar.dll :- could you go rclick Start > explore > tools tab > folder options > view, and select Show hidden files and folders, and then do a search for that file? Post here where you find it. And may i ask how you have tried to remove isearch previously? Make sure that it has been removed from Control panel > Add/Remove programs list.
=Meanwhile would you download CCleaner from http://www.ccleaner.com/ - and put it in a new folder. You should aim to keep this one for general use. I set it from the install checkboxes to only open from the recycle bin. It's neater that way.
=Get Adaware SE Personal from http://www.lavasoft.de/software/adaware/
- install it. Update it. Explore what settings you can change in it [via the cogwheel icon up top, if you are comfortable with that... you won't hurt anything, but for the moment leave it with the default settings]. Put an icon on your desktop for regular use.
=Download this temp file cleaner from http://www.atribune.org/ccount/click.php?id=1 -click in the download window to run it, then when ATF Cleaner opens go Select all, and then Empty Selected.
Next click Firefox at the top, Select All again, and Empty Selected again. Close ATF.
Restart you computer in Safe Mode [press F8 several times while POST is running and before IDE detection completes - you will, after login and safe mode selection, get a black screen with some of your icons... Run Adaware, doing a full system scan and finally remove all that it finds [rclick in the scan results window and select all, go next..].
Continue to normal mode, start Hijackthis and then close ALL other open windows and apps, and then select Scan Only. Check against the two entries below if they exist, and fix them.

Well, did it work? Let me know...., plus whether you found toolbar.dll.
