I had a virus removed from my virus scanner (NOD32), the file was c:\windows\system32\pmnlm.exe
NOD32 claimed that it cleaned this virus. I noticed something was wrong when a few programs were missing the .exe files - that is, when you click on the .exe, windows just browses for the file and doesn't find it. This pmnlm.exe file was set to run at startup, i checked in msconfig startup and disabled it to run at startup. Now after the virus cleansing by NOD32, the pmnlm.exe file is still there (although it's dll files aren't), and NOD32 doesn't detect it as a virus anymore. A person on this forum has had the same problem as me over here: http://www.bleepingcomputer.com/forums/t/125409/infected-wvundo-virtumonde/

I have the same symptoms as him, even the general slowdown of the computer - programs take longer to load etc. I ran vundofix and here is the log file from it:

Next, I checked msconfig again and now there is a file in c:\windows\system32\ssttr.exe which is set to run at system startup. In the msconfig window it's location is here: HKCU\SOFTWARE\Microsoft\WindowsNT\Currentversion\Windows:Load
This looks suspicious and that pmnlm.exe file is still present.

edit: I've just ran another scan from NOD32 and it says this:
application Win32/Adware.Virtumonde.FP found in operating memory. System memory infection originated from file C:\WINDOWS\system32\ssttr.dll.

C:\System Volume Information\_restore{0BD74437-0F09-4468-97A6-81924F51D7BA}\RP249\A0037744.dll - Win32/Adware.Virtumonde.FP application

C:\VundoFix Backups\pmnlm.dll.bad - Win32/Adware.Virtumonde.FP application

C:\WINDOWS\system32\ssttr.dll - Win32/Adware.Virtumonde.FP application

NOD32 claims now it deleted all 3 of those.

Here is the hijack this logfile:

Welcome to the BleepingComputer HijackThis Logs and Analysis forum mr-scarface
My name is Richie and i'll be helping you to fix your problems.

You’re running msconfig in Auto mode which means that you may have selectively unchecked some items in the past from starting up with Windows.
This can be bad if they’re malware, so please re-enable those startup entries by doing the following:
Click on Start>Run,type msconfig and then press Enter.
When the ‘System Configuration Utility’ opens click on the ‘Startup’ tab,make sure all the boxes are checkmarked.
Then press Apply/Ok to exit the utility.
If it asks you to restart your pc,please don’t,it‘s not necessary at this point.

Please visit this webpage for instructions for downloading and running ComboFix.
This includes installing the Windows XP Recovery Console in case you have not installed it yet.

Post the entire contents of C:\ComboFix.txt into your next reply.
Also post a new Hijackthis log.
