Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

First we want to check and see if you have anything malicious on your system such as a virus or spyware

Download  combofix.exe and save it to your desktop
Close any open browsers.
Before starting ComboFix disable and exit any anti-virus software, anti-spyware or any other security related software as they may interfere with ComboFix's operation.
Double click combofix.exe & follow the prompts.
When finished, it shall produce a log for you and display it on your desktop called c:\combofix.txt. By default this log is located on your 'C' drive. Post that log in your next reply
Note:Do not mouseclick combofix's window whilst it's running. That may cause it to stall.

Also download and run hijack this

Also run these

your going to need some anti spyware /malware utlities run too spybot s&d - download it install it (do not install tea timer, ) update it then run it - adaware - download it run it and then uninstall it    - select to only download and install spyware doctor.

Additionally I would download and run rootkit revealer if it comes up with anything odd post it up here.
This could also be a problem with the memory, a corrupted profile or corrupted windows ..

To test for a profile problem go to control panel then users and create a new user account assign it a name and password then logoff and login with that account if the error does not occur then it is a problem with your user account / profile. You will need to transfer the data from your old profile to a newly created one.

Thanks Brian - I will have availibility to the laptop on Monday to try the various solutions.
The laptop belongs to a network so will test the corrupt profile first.
What is the important thing to look at in the combofix txt doc?
the combofix is going to produce a log file, that log file will show what was removed and what else it found the other things it finds has to be verified by using a search engine on the internet and looking up any suspicious dll's and .exe files.

Same as you would do for a hijack this log file.
If you post the logfiles here though myself or someone else can review it and then instruct you where to go from there.
