  (XP users click run after receipt of Windows Security Warning - Open File).
• Press the Fix button just once and wait.

I noticed a very interesting behavior this morning. So I booted the machine and immediately logged into my account, and as usual, no signs of the com surrogate on the task manager process list. I opened up windows explorer to navigate to my wife's account\desktop to grab the fixlog file, and the dllhost com surrogate popped up. I quickly performed a copy on the log file and closed the windows explorer window, and the process went away. I then repeated the process one more time just to see if it was repeatable, and sure enough, the same thing happened. It seems as though the infection resides in her account somewhere. I'm not sure if any of this helps you or not, but it was something that I observed, and figured I should tell you. I'll be rebooting shortly under her account and running an FRST scan...

You're talking about Task Manager. If you have one dllhost.exe it is normal.

 

[viper8315]

Yes, but it was a dllhost process with the Com Surrogate description. When I just rebooted, and logged into my wife's account, I did see a couple dllhost com surrogate processes popup on the task manager then go away. I've attached fresh logs from a scan performed on my wife's account.

 

[TwinHeadedEagle]

These reports look clean.

 

[viper8315]

Ok....so I only see the dllhost.exe com surrogate pop up for about a minute, then go away now. Is this normal?

 

[TwinHeadedEagle]

One is normal

Wait a day and let me know if everything is all right.

 

[viper8315]

Well, I guess everything is ok. Other than I see a pile of svchost processes. Maybe I'm a bit paranoid now...never had an infection as bad as this...
