Hi nikid506,
Let's rule out possible malware first.
Please set your system to show all files; please see here if you're unsure how to do this.
Reboot into Safe Mode: please see here if you are not sure how to do this.
Using Windows Explorer, locate the following files/folders, and delete them:
C:\WINDOWS\SYSTEM32\mobho.dll<=file
Exit Explorer, and reboot as normal afterwards.
GMER
Please create a new subfolder in the Program Files folder called GMER. If you have an older version of GMER installed, you must delete it.DO NOT touch the PC at ALL for Whatever reason/s until it has 100% completed its scan, or attempted scan in case of some error etc !
- Download GMER and extract it to the C:\program files\GMER folder.
- Please rename the GMER file
Note: You can rename gmer.exe to anything you like as long as you keep the .exe ending.
Run the Gmer.exe renamed program by double-clicking the executable file (gmer.exe) in Windows Explorer.
You may be prompted to scan immediately if GMER detects rootkit activity.- If you are prompted to scan your system click "yes" to begin the scan.
- If you are not prompted, Click the "Rootkit" tab, then click "Scan".
At the end of the scan, click "Copy" to copy the scan results to the clipboard. Then paste the results in a notepad file and also paste them back in your next reply.
Please post (reply) with the results from the GMER scan, and a fresh hijackthis log.
=============================
If you have your Dell manual (I am looking at one called "Reference and Troubleshooting Guide"), there should be a section "Running the Dell Diagnostics" which tells you how to use the Dell Dimension ResourceCD to check your hardware. I would recommend that you do this and record and messages that you receive. This is out of my expertise but you may need to go to the Dell boards and receive help with this. Please let me know if you have the documentation for running the diagnostics.
Susan,
I have not idea how to start a fresh forum, so I'm naming this one Part 2, not the most brillaint idea. Anway, here is my log – I was able to delete that file in safe mode as well. I have the Dell Dimension ResourceCD for Reinstalling Device Driver etc…but no manual. I'll go online and see if I can get it. See below for my log. Thank you in advance. Nicole
