Iam having problems with malwarebytes hope its the right place my operating system takes about 5min to shut down with it installed as soon as i end it from task manager the os will shut down in seconds any help would be appreciated i am using windows vista 32 bit.

What version of Malwarebytes do you have? It should be 1.39 on the About tab. What AV/Firewall do you have, so we can check to see if thats holding it up. Some AV programs need a manual configuration with mbam files. If that be the case. Post back please with some answers to the above...regards..
