Greetings
My apologies for taking so long to reply. If you're still having this issue please try the following:
Step 1: Verify Internet Connectivity Registry Settings:
Backup the Registry:
Modifying the Registry can create unforeseen problems, so it always wise to create a backup before doing so.
- Please download ERUNT from here
- ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.
- Double click on erunt-setup.exe to Install ERUNT by following the prompts.
- Use the default install settings but say NO to the portion that asks you to add ERUNT to the Start-Up folder. You can enable this option later if you wish.
- Start ERUNT either by double clicking on the desktop icon or choosing to start the program at the end of the setup process.
- Choose a location for the backup.
- Note: the default location is C:\Windows\ERDNT which is acceptable.
- Make sure that at least the first two check boxes are selected.
- Click on OK
- Then click on YES to create the folder.
Note: if it is necessary to restore the registry, open the backup folder and start ERDNT.exe
Once you've completed backing up your Registry, please do the following:
Step 2: Verify Your Internet Connection Settings:
- Open Internet Explorer
- Note: It MUST be Internet Explorer, not Firefox, Opera, Chrome or any other internet browser
- Click on Tools at the top and select Internet Options
- Note: If you do not see Tools, press the Alt key on your keyboard and it will show up
- Click on the Connections tab
- Click on the LAN settings button
- Under Automatic configuration make sure that the box next to Automatically detect settings is checked, if it is not, then click the box next to it to check it
- Click on the OK button to close the Local Area Network (LAN) Settings window
- Click on the OK button to close the Internet Options window
- Try updating Malwarebytes' Anti-Malware again to see if it now works correctly
Now try updating Malwarebytes' Anti-Malware once more and if it does not work then please proceed to
