syshost.exe appeares in my scans

[Pkosiarek]

I have the syshost.exe trojan on my laptop. It will not delete when I run the Mawarebytes. It just says Opperation Failed, error 2. This is what shows up when I run the malwarebytes system:

(end)

This is what shows up in my RK report (which explains why Google.com does not work).

Welcome to the forum.

Please make sure system restore is running and create a new restore point before continuing.

First Thank you for helping!

Second, I completed the scan. I hit the contuine button. It did not ask me to cure or reboot. I attached the report.TDSSKiller.2.7.48.0_05.08.2012_10.34.27_log.txt

When you reply please use the standard font and click on the "More Options Buttons" on the right bottom corner of the page, and then post on the new page that comes up.

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

Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix

http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.

---------->NOTE<----------

If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.
