Hi there,

posted this a couple of days ago and got redirected to this forum:

A few months ago I got infected by the XP recovery virus (Windows XP, Home Edition, Service Pack 3).

I was able to use MalewareBytes in safe mode to get rid of the worst of the infection.

However, since then, I've still been getting browser re-directs; TDSSkiller won't open (despite being renamed),
and AntiVir is detecting a 'BOOtdss.D' infection (although it cannot remove this, just runs a scan a does nothing).

-------------------------------------------------------------------------------------------

Following on from that original post, have now done the DDS and GMER scans, so now can now
provide the logs from those. (They seem to suggest it's the TDL4@MBR code?)

Anyway, as said, thanks for any ideas.

Sprokky.

Click on the Watch Topic Button and select Immediate Notification and click on proceed, this will help you to get notified faster when I have replied and make the cleaning process faster.

Please print out or make a copy in notpad of any instructions given, as sometimes it is necessary to go offline and you will lose access to them.

Run Combofix:

You may be asked to install or update the Recovery Console (Win XP Only) if this happens please allow it to do so (you will need to be connected to the internet for this)

Before you run Combofix I will need you to turn off any security software you have running, If you do not know how to do this you can find out >here< or >here<

Combofix may need to reboot your computer more than once to do its job this is normal.

You can download Combofix from one of these links.

Link 2
Link 3

1. Close any open browsers or any other programs that are open.
2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Double click on combofix.exe & follow the prompts.
When finished, it will produce a report for you.

Note 1: Do not mouseclick combofix's window while it's running. That may cause it to stall

Note 2: If you recieve an error "Illegal operation attempted on a registery key that has been marked for deletion." Please restart the computer

"information and logs"

In your next post I need the following
