If you cannot use the Internet or download any required programs
to the infected machine, you are going to need access to another computer (family member, friend, library etc) with an Internet connection. Save mbam-setup.exe
to a flash (usb, pen, thumb, jump) drive or CD, transfer it to the infected machine, then install and run the program. If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe
so it will install on the hard drive. If you cannot copy files to your usb drive, make sure its not "Write Protected
". Some flash drives have a switch on the side which could have accidentally been moved to write protect.
-- Some types of malware will disable Malwarebytes Anti-Malware and other security tools. If MBAM will not install, try renaming
- Right-click on the mbam-setup.exe file file and rename it to mysetup.exe.
- Double-click on mysetup.exe to start the installation.
- If that did not work, then try renaming and changing the file extension. <- click this link if you do not see the file extension
- Right-click on the mbam-setup.exe file, rename it to mysetup and change the .exe extension to .scr, .com, .pif, or .bat.
- Then double-click on mysetup.scr (or whatever extension you renamed it) to begin installation.
If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
If using Windows Vista, refer to How to Change a File Extension in Windows Vista.Note: MBAM uses Inno Setup instead of the Windows Installer Service to install the program. If installation fails in normal mode, try installing and scanning in safe mode. Doing this is usually not advised as MBAM is designed to be at full power when running in normal mode and loses some effectiveness for detection & removal when used in safe mode. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM. Therefore, after completing a scan it is recommended to uninstall MBAM, then reinstall it in normal mode and perform another Quick Scan.
