Ok here you are! By the way not even once did malwarebytes find something.

And the HJT. Where are you from incidentally?

Strange the log didn't upload last time. Now it's saying the file is invalid

Still honestly see NOTHING in that HJT log. Very strange. Did you try my other suggestions?
Only thing I see as "risky" in the HJT log is this entry;
O4 - HKCU\..\Run: [BitTorrent DNA] "C:\Users\Padraig\Program Files\DNA\btdna.exe"
Not really a wise idea to have this running automatically at start up, meaning then it is running all the time usually.
I'm not going to get into a big lecture on P2P here, forum policy on P2P is NO to that entirely and must say I agree. It can and often does lead to major infections, some of which the only way to recover is wiping the drive. But don't feel this is that type of case really...though cannot say for sure. Whatever and whereever this searchbar came from it obviously isn't a good place, we both found that when checking out their web page.

Ok, but I have been using p2p for many a year now and am not about to stop.

So looks like I'm stuck with this search bar for another while.

Thanks for your time.

This search bar IS malware. There has to be a way to get rid of it.

We really need a more thorough look at what is going on before we can say that
HijackThis is often insufficient when it comes to today's malware - Let's try this:

-- Download DDS by sUBs and save it to your Desktop
-- If your AV has a script blocker, please disable it
-- DoubleClick on dds.scr to run the tool

* A command box will open, displaying added information for your reading pleasure while DDS completes its scan.
* Upon completion, a Dialog Box should open instructing you to save and post the TWO resulting logs (DDS.txt & Attach.txt).
Please post Attach.txt as an attachment to your post - there is no need to Zip it. If you don’t know how to post an attachment, please Copy&Paste it along with the DDS.txt scanlog.

Judy, I, or one of the other volunteers will have a look as time permits.

Cheers
PP

Thanks a lot. This this is really starting to ......

I'm sorry - I should have written that more clearly.
I need you to copy and paste the main DDS.txt for me. That's the one I really want to see.
If you didn't save that log, just run DDS again.

As for the toolbar, I have a feeling that it might be one of those "quasi-legit" items that comes bundled in the installation package with another program you might have installed.
I know you said it "just appeared," but maybe she didn't notice it before? Do you remember installing any new software around the time the nuisance bar appeared?

Let's see what we find in the DDS.txt - Just copy and paste that one.

I'll be back tonight.
