Multiple dllhost.exe, msiexec.exe and cmd.exe

[Eric Jones]

I've attached both scan logs from FRST.

Also, this PC is a company machine and thus has some software that may be unrecognized compared to a typical "home" computer. I'm pretty knowledgeable about what that Company software is, so I'll let you know if something I'm asked to remove is necessary to the operations of this computer.

If an error about operation on the key marked for deletion will appear after running the tool, please reboot your machine.

Is it better to run Combofix in Safe Mode, or should I just run it from a normal windows session?

 

[TwinHeadedEagle]

Safe Mode should be used only when Normal mode isn't accessible.

Here is the ComboFix log

 

[Eric Jones]

I have not rebooted and I still see a number of cmd.exe, dllhost.exe and msiexec.exe processes.

Let's use FRST again:

Still sluggish. Still has cmd.exe, msiexec.com, and dllhost.exe files running.

[Eric Jones]

Sorry for the delay. I plan to work on the check disk today!

 

[TwinHeadedEagle]

No problem, I'll be waiting.

 

[Eric Jones]

I am unable to do the last part about copying data from the Event Viewer. There doesn't appear to be any events tied to a chkdsk either upon scanning through the list. Maybe XP doesn't do that part? Regardless, when it did the check disk, it said disk was clean on the window that ran. Also, after the reboot, the system is running much better and i'm not seeing the rogue processes!

 

[TwinHeadedEagle]

It doesn't matter if you cannot find the log.

Is everything fine now?
