Hello, A couple of days ago on 8-4-2014 my malwarebytes (full version, windows 8.1 64-bit), program wouldn't open. I'm also running Vipre security for anti-virus purposes. I can open Vipre just fine. I double click on malware icon and nothing happens. I have already tried going through computer>C:Drive>ProgramFiles(x86)>malwarebytes anti-malware>chameleon>windows>chameleon and tried clicking several of the links. Each time I clicked on a link, a black box appeared stating: MBAM-Chameleon ver. 3.0.4 press any key continue...so I do. Then a new dialog box appears which states malwarebytes has stopped working. I can either checkk online for a solution and close the program, or close the program. When I click on either option the result is the same: nothing happens, the box goes away and the scan continues. The scan reads: Trying to start malwarebytes please wait...Done! (then it says...) Updating MBAM...Response from update: Failed to start the update. Killing known malicious processes please wait...MBAM-killer Timeout set to 1800 seconds. Mbam-killer encountered an exception initializing - Integrity verification failed - 4e35 (it repeats this message 4 more times) A Reboot is recommended to remove temporary directory C:\Program Files (x86)\Malwarebyes Anti-malware\Chameleon\Windows\zmixdjstmp Malwarebytes has terminated - unable to start the scan...Removing protection drive...Done! How should I proceed and how could have malware slipped past your software?? Thank you.
