I am running Vista, and mcafee

Hello and :welcome:

Please try the following to see if it helps and get back with us with any errors:

Windows Vista and Windows 7:

  • Click on the Start vista-7-start.png button and select Control Panel
  • Click on Programs and Features
  • Uninstall Malwarebytes' Anti-Malware
  • Restart your computer very important
  • Download and run mbam-clean.exe from here
  • NOTE: If you get SHGetValue failed with error code 0, that only means that the tool has nothing to perform, continue on with the next step....
  • It will ask to restart your computer, please allow it to do so very important
  • After the computer restarts, temporarily disable your Anti-Virus and install the latest version of Malwarebytes' Anti-Malware from here
    • Note: You will need to reactivate the program using the license you were sent via email if using the Pro version
    • Launch the program and set the Protection and Registration. Then go to the UPDATE tab if not done during installation and check for updates.
      Restart the computer again and verify that MBAM is in the task tray if using the Pro version. Now setup any file exclusions as may be required in your Anti-Virus/Internet-Security/Firewall applications and restart your Anti-Virus/Internet-Security applications. You may use the guides posted in the FAQ's here or ask me and I'll explain how to do it.

Well doing a google search for your problem has revielled to different fixes or comments on the error...

1. Your Mcaffe is causing the problem

2. You may have malware.

I think we need to make sure you don't have malware on your computer, so I think you need to go seek assistance from the experts and make sure your system is clean first.

Please read the following so that you can begin the cleaning process:

As we don't deal with malware removal in the General Malwarebytes' Anti-Malware Forum, you need to start a topic in the Malware Removal forum so a qualified helper can help you fix any malware related problems/infections you may have.

  • Please read and follow the directions here, skipping any steps you are unable to complete. Then post a NEW topic here.
  • After posting your new post, make sure under options, you select Track this topic and choose Immediate Email Notification, so that you're alerted when someone has replied to your post.
  • One of the expert helpers there will give you one-on-one assistance when one becomes available.
  • Please refrain from making any further changes to your computer (Install/Uninstall programs, use special fix tools, delete files, edit the registry, etc...) unless advised by a malware removal helper. Doing so can result in system changes which may hinder the attempts by a helper to clean your machine.

NOTE: Please DO NOT post back to (bump) your topic within the first 48 hours.

Replying to your own posts changes the post count and helpers are looking for topics with zero replies. If you reply to your own post helpers may think that you're already being helped and thus overlook your post.

    • If there is no reply from any experts after 48 hours, you can reply to the topic, asking for help again.
      Or
    • You may send a Private Message to a Moderator asking for assistance.

Alternatively, as a paying customer, you can contact the help desk at support@malwarebytes.org or here.

Please be patient, someone will assist you as soon as it is possible.

PS: Please use the "ADDREPLY" t_reply.gif button instead of other ones when you start replying. :welcome:
