when i shut down ....

Recently i got zapped with a X Password Gen, and a hidden virus, which wreaked havoc on my system.
i used AVG to clear it, but i still get a "you should not see me" dialog box as the system shuts down, ( one of those "xxxxxx.dll ending program" boxes)... is there someway to find out if this is something nasty still in the system?

 

Here is how we like to begin our analysis of your pc:

For starters, if you do not have them yet, please DL and run AdAware & Spybot Search & Destroy. AdAware and Spybot Search & Destroy are 2 of the most trusted apps in the security area. They are both free, compliment each other nicely, and do not use a lot of resources. They can be found here:

Spybot Search & Destroy v.1.4
AdAware SE Free v1.06r

With AdAware and Spybot: DL, follow the install instructions, check for updates, then scan, repair/remove/quarantine anything found. Reboot before next scan with whichever app is next. The reason for running these apps, is to clean up some of the other 'crapware' on your pc, which, in turn, will make deciphering your HJT log, easier.

Then we use HiJackThis v:1.99.1zip.
DL the zip file to your desktop, then create a new folder on your C drive, called 'HJT' or 'HijackThis'. Then unzip the files to the new folder. When you run HijackThis.exe from C:\HJT folder and have it "Fixed checked" it will create a backup file of modifications to use if restore is necessary which is easily accessible.

Run the program, and press Scan. You will notice the Scan button will turn into a "Save Log" button. Save the log and Post that log onto this topic. DO NOT DELETE or modify anything yet, as some of it is needed to keep your system in proper working order.
