I seem to have picked something up in the last day. Running Win XPP SP3, FF 15.0.1, with Chrome (currently 19.0) as a backup. I’m getting multiple blocked URL messages, to the point that browsing is impossible. The popup box says URL:Mal
Logs attached for OTL, aswMBR and FSS. MBAM log to follow in next post.
Thanks in advance!

A couple of screenshots - popups when I was reading this post.
I did the OTL Run Fix above. On the reboot, the machine hung on a bios splash screen. I shut it down (power button) and then restarted. It restarted normally into Windows and then OTL started.
I ran the quick scan - log attached.
I ran RogueKiller as instructed. Log attached.
btw… thank you for you help so far, Pondus and essexboy. Much appreciated.

Ran Combofix. Log attached.
While combofix was running a few Windows error reporting dialogue boxes popped up. PEV.exe, Realtek HD Audio, Paperport Print to desktop for NT and brctrcen.exe. I recognise all but the first as programs that normally run on this machine.
Will report back at the end of the day about how it’s going. No URL:Mal pop-ups in FF so far.
Let me know if all is well tomorrow and I will tidy up
I’m pleased to report that nothing happened the whole day. No pop-ups from avast! running FF all day (now updated to FF16.0.1), no connection drop-outs.
Looks promising! 
Subject to no further problems 
I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems
Now the best part of the day ----- Your log now appears clean 
A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:
Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following
:Commands [resethosts] [emptytemp] [CLEARALLRESTOREPOINTS] [Reboot]
[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done
Remove ComboFix
[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall
(Notice the space between the “x” and “/”)
then click OK
http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg
[]Follow the prompts on the screen
[]A message should appear confirming that ComboFix was uninstalled
Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.
We will now confirm that your hidden files are set to that, as some of the tools I use will change that
[*]Click Start.
[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.
Update and run weekly to keep your system clean
Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link
It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit
[*]Microsoft Windows Update
To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ?Keep safe 
Happily, there has been nothing to report in the last week, so it looks like its all fixed. Thanks again essexboy, I’m grateful for you sharing your time and expertise.
I will run the cleanups now.
