Hi trevari, welcome to DaniWeb
1. I've moved your thread to the appropriate forum.
2. The problem you describe is a symptom of the SpySheriff/Smitfraud group of infections; here's the specific fix for regaining full functionality of your desktop properties:
Download the smitfraud.reg file by right-clicking on
this link and choosing "Save link as..." or "Save target as..." from the resulting pop-up menu. Save the file to your desktop.
- Double-click the smitfraud.reg file you saved, and when it asks if you want to merge with the registry, click
YES.
- Reboot your computer; your display properties should be returned to normal.
3. As the others have suggested, post a HijackThis log for us to review:
Download the (free) HijackThis utility:
http://www.stevewolfonline.com/Downl...HijackThis.exe
Once downloaded, follow these instructions to install and run the program:
Create a folder for HJT outside of any Temp/Temporary folders and move/extract HijackThis to that folder now. A folder such such as C:\HijackThis or C:\Spyware Tools\HijackThis will do.
Run HijackThis, but do not have HJT fix anything yet; only have it scan your system! Once the scan is complete, the "Scan" button will turn into an option to "Save log...".
Save the log in the folder you created for HijackThis; the saved file will be named "hijackthis.log". Open the log file with Windows Notepad, and cut-n-paste the entire contents of the Notepad file here.
The log contents will tell us a lot about what "nasties" have crept into your system, and once we analyse the log we can tell you what to do from there.
