I've been told that my computer has a trojan lurking on it but nothing seems to pick it up. I've run Superantispyware, Malwarebytes and Kaspersky online scan and they all came back clean. The main reason for suspecting a trojan is that an extra CD drive has appeared and that Hijack and Combofix logs seem to suggest that it's there. Can anyone help?

May I suggest you fully update the Malwarebytes and Superantispyware programs; run full deep scans with both and post those reports for review;

also please note the warning about running ComboFix

ComboFix is a tool that should only be run under the supervision of someone who has been trained in its use. Using it on your own can cause problems with your computer.

This includes preventing the computer from ever running again :thumbsup:

Lets see those requested reports and go from there?

I updated both programs when I ran the scans last night and both were clean apart from tracking cookies discovered by superantispyware. Here's the log of malwarebytes. I don't know how to get the other report back!

(edited out bit about ComboFix; thanks )
Dare one ask who recommended the ComboFix ?
PLEASE DO post the reports from Malwarebytes and superantispyware :thumbsup:

Lets see the superantispyware report ; but NOT the HJT one

maybe run another superantispyware scan , but OFF line and in safe mode is best

I did not notice a HJT report in this thread; maybe I missed it :flowers:

Done! Should I remove the hijack report as well since it shouldn't be in this section? (EDIT: Maybe I never posted it? I thought I did! Anyway, doesn't matter since it shouldn't be here!) I've just noticed that! How do I get the superantispyware report back again or do I just have to run another full scan?

Oh forgot to add; it was someone on a totally different forum who recommended it!

With regards to the ATF cleaner, the firefox option doesn't show up even though I have firefox. Why's this and does it matter?

You are clean

The main reason for suspecting a trojan is that an extra CD drive has appeared


Do you use any virtual machine software?
It could also be software that uses hardware emulation
One example of this is U3-enabled thumb drives, like some
of the Kingston DataTraveler drives and the Cruzer Micros, and
another example is CD Daemon or CD image software that loads ISO, BIN,
NRG, CCD, and other CD image filetypes as a physical CD drive.

Well I'm pleased to report that the extra drive has disappeared again! Not sure why, or what happened to make it do so! There was no virtual drive software as far as I know and the only things I installed recently were EasyBCD and Partition Magic, both of which have now been uninstalled. Many thanks for all your help.

Only other niggle now is that after being recommended to run the Combofix tool by a different forum, I've got this windows recovery console which flashes up during startup. How do I permanently remove that, or is doing so not a good idea?

Keep the Recovery Console. That is a good thing
I would uninstall Combofix though

  • Click on your Start Menu, then Run....
  • Now type combofix /u in the runbox and click OK.
    Notice the space between the "x" and "/".

  • When shown the disclaimer, Select "2"
This will remove files/folders assoicated with combofix and uninstall it.

Ok many thanks for your help. I tried the above method and it said Combofix didn't exist so I assume it already is uninstalled.
