Cannot install MB

[gailee]

All programs are missing from the start menu and cannot be viewed in my computer (run through usb drive). Avast scanning shows all programs being scanned. Ran cmd through task manager and only docs & settings showing on c drive. Tried to install MB from usb drive and get access denied, set up not complete please correct the problem and try again. Tried several times, one error popped up: mbam_error_expanding_variable (0,453),please report to support team. When trying to install Super Antispyware I am asked to modify, repair or remove so obviously it is in the system but I cant get to it to run it. Ran tuneup utilities and cc cleaner. All installed programs are listed in cc cleaner and windows install cleanup. This is a dell optiplex 330 running winxp sp3

Hello and welcome to Malwarebytes

Sounds like you are infected, here are the steps needed to get your computer cleaned....

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

Don't use any temporary file cleaners unless requested - this can cause data loss and make recovery difficult

You have 3 Options that you can choose from as listed below:

• Option 1 —— Free Expert advice in the Malware Removal Forum
  
• Option 2 —— Paying customer -- Contact Support via email
  
• Option 3 —— Premium, Fee-Based Support

OPTION 1

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 (http://www.malwarebytes.org/forums/index.php?showtopic=9573), skipping any steps you are unable to complete.
  
• 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.

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.
