I haven't read back through over 70 posts but I looked at the log and don't see anything malicious. There is one item of foistware that should be removed via the Control Panel - Add/Remove programs and that is anything with the following names:
Viewpoint
Viewpoint Manager
Viewpoint Media Player
As for the userinit.exe file, the valid file should be in System32 whereas a Haxdoor file would likely be in C:\Windows
Keep in mind even the userinit.exe in the valid location can be infected but I don't see any signs of infection in your HijackThis log, although not everything would show in a HijackThis log.
I also noted two anti-virus programs but I'm sure that would have been mentioned that you should uninstall one of them.
I will ask for a couple of simple scans which will tell us more but I won't move the thread just yet.
Download GMER from:
http://gmer.net/index.php
Save it on your desktop and unzip it.
Double click the gmer.exe to run it and select the rootkit tab and press scan. When the scan is done, click
Copy. This will copy the report to the clipboard. Paste it into Notepad and save it and also paste the log report back here please.
Please download Malwarebytes Anti-Malware form
Here or
Here
Double Click mbam-setup.exe to install the application.
- Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
- If an update is found, it will download and install the latest version.
- Once the program has loaded, select "Perform Quick Scan", then click Scan.
- The scan may take some time to finish,so please be patient.
- When the scan is complete, click OK, then Show Results to view the results.
- Make sure that everything is checked, and click Remove Selected.
- When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
- The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
- Copy and paste the entire report in your next reply along with a new HijackThis log please.
Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediatly.
Also, if you receive an (Error Loading) error on reboot please reboot a second time . It is normal for this error to occur once and does not need to be reported unless it returns on future reboots.
