Hi,

Yesterday I changed firewall from ZoneAlarm to Kerio PF and after I was finished installing the new one, two processes asked permission to the Internet; lsass.exe and rxhostt.exe.

I know what lsass.exe is but have no idea what rxhostt.exe is. I have enclosed my log below:

I don't know exactly what it is, but I am certain that you do NOT want it on your computer!

Have Hijack This fix all of the following by placing a check in the appropriate boxes and hitting fix checked. Make sure all browser and all Windows Explorer windows are closed before fixing.

O4 - HKLM\..\Run: [Microsoft Update Machine] rxhostt.exe
O4 - HKLM\..\RunServices: [Microsoft Update Machine] rxhostt.exe
O4 - HKCU\..\Run: [Microsoft Update Machine] rxhostt.exe

Reboot and delete the file rxhostt.exe

These may be hidden files. See HERE for how to show hidden files.

Please post a followup Hijack this log, and say if your problems persist.
Be wary of strong drink. It may make you shoot at tax collectors, and miss!

Hi,
Thanks for the reply! I checked the boxes you specified and rebooted, however I was unable to delete rxhostt.exe because it said it was used by another application. Therefore, it rebooted in safe mode where I was able to delete the file. I also found another rxhostt.exe which was named: rxhostt.exe-233AD399.pf located in C:\WINDOWS\Prefetch.

I deleted that file as well. Below is my latest log file (I have updated my system with the SP1 among other updates since my first post):

The only "problem" I seem to have now is that when I start up the computer, it takes a very long while before it loads the msn and Norton Anti-Virus applications. Dont know why, something to do with the updates I have installed?

EDIT: jeez! I see that the rxhostt.exe is still there....I will run hijackthis again and then reboot directly into safe mode and delete again.

Ok, I have run hijackthis again and checked the specified boxes again. Then I rebooted into safe mode, but no files were found (apparantly they were deleted the first time...)

This is what my log file looks like now:

But as I said in the previous post, the system is really slow and it takes forever for msn messenger and Norton AV to log on...
