How to remove the 'wallpapercave' trojan?

[universemal]

I'm getting a message from Malwarebytes that it is blocking an outgoing call from wallpapercave because it is a trojan. I have searched my PC in Control Panel and by searching the complete registry but do not see wallpapercave mentioned. Does anyone know how to find and delete wallpapercave? Thanks.

Hello @universemal and

 

Let's go ahead and run a couple of scans and get some updated logs from your system. Please read the entire post below before starting so that you're more familiar with the process

[ 1 ]

Please make the following system changes.

• Temporarily disable your antivirus real-time protection or other security software first only if it blocks or interferes with the scans or downloads.. Make sure to turn it back on once the scans are completed.
• Temporarily disable Microsoft SmartScreen to download software below only if needed. Make sure to turn it back on once the scans are completed.
• Disable-Fast-Startup
• Show-Hidden-Folders-Files-Extensions

Malwarebytes AdwCleaner

Let's do a special run of Malwarebytes AdwCleaner to help prepare the computer to be able to run other scanning software that may be blocked

Please read all the information below before starting so that you have a good understanding of the process.
Take your time and be careful. Make sure you select all of the listed items below - before- pressing the scan button.

 

• Please download Malwarebytes AdwCleaner and save the file to your Desktop or Downloads folder.
• Here is another link to download if the link above does not work:  Malwarebytes AdwCleaner alternative link
• Locate the program where you downloaded it. Double-click to start AdwCleaner.  Do not rush. There are a few choices to set as listed below.
• Malwarebytes AdwCleaner guide
• Reply YES at the Windows prompt to allow the program to proceed and make changes. That is the usual Windows security prompt.
• Accept the End User License Agreement.
• Wait until the database is updated. Do Not click on anything yet.

 

When AdwCleaner starts, on the left side panel of the window, click on Settings and enable these repair actions on the Application tab

Clicking their button to the far-right will enable the ON status

 

• Delete IFEO keys
• Delete tracing keys
• Delete Prefetch files
• Reset Proxy
• Reset Chrome policies
• Reset IE Policies
• Reset Winsock
• Reset Hosts file (If you're not having any issues accessing security or other websites you can uncheck this item)

 

 

ONLY after you have set the selections above ....only after that .....

Now On the left side of the AdwCleaner window, click on the Dashboard panel and then click the Scan button to perform a computer scan.

 

 

• DO NOT uninstall or remove the Preinstalled software if found. Uncheck any items listed for Preinstalled
• When finished, if items are found please click Quarantine to finish the cleaning process.
• Your PC should reboot now if any items were found.
• After reboot, a log file will be opened. Attach that log to your next reply. You can also open the Log Files panel to locate.
• This can take several minutes to complete, please be patient.
• When the AdwCleaner scan is completed it will display all of the items it has found. Click on the Quarantine button To remove what it found.
• AdwCleaner will now prompt you to save any open files or data as the program will need to close any open programs before it starts to clean.
• Click on the Continue button to finish the removal process.
• If No Detections are found, Click the Basic Repair button to have it reset the checked items above.

To add: The warning message that 'wallpapercave' is sending a trojan from Malwarebytes occurs randomly, but I always get the warning when I save the image present by default when MS Edge is on its start up page.

Please run the items above
