Can you use another computer and download it to a thumb drive?
Here's all the tips I have for Mbam:
Some types of malware will target Malwarebytes Anti-Malware and other security tools to keep them from running properly. If MBAM will not install, try renaming
Note: Malwarebytes Anti-Malware uses Inno Setup instead of the Windows Installer Service to install the program. If installation coninues to fail 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.
- Right-click on the mbam-setup.exe file file and rename it to mysetup.exe. If that did not work, rename it explorer.exe.
- Double-click on the renamed file to start the installation.
- If that still did not work, then try changing the file extension. <- click this link if you do not see the file extension
If using Windows Vista, refer to these instructions.
- Right-click on explorer.exe and change the .exe extension to .scr, .com, .pif, or .bat.
- Then double-click on explorer.com (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.
- Right-click on mbam.exe and rename it to wuauclt.exe.
- Double-click on wuauclt.exe to launch the program.
- If that did not work, then change the .exe extension in the same way as noted above.
- Double-click on wuauclt.com (or whatever extension you renamed it) to launch the program.
If that does not work, you can try using Rkill before
scanning with Malwarebytes Anti-Malware. This tool terminates certain processes and fixes certain registry keys that stop us from using security and clean up tools. Please download Rkill
by Grinler and save it to your desktop.Link 2Link 3Link 4
- Double-click on the Rkill desktop icon to run the tool.
- If using Vista, right-click on it and Run As Administrator.
- A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
- If not, delete the file, then download and use the one provided in Link 2.
- If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
- Do not reboot until after scanning with Malwarebytes Anti-Malware.
-- Other types of malware may delete
the main mbam.exe
executable file during installation or when attempting to perform a scan which results in various errors such as code 2...The system cannot find the file specified
or mbam.exe - Application error
One way to resolve this is to download and install Malwarebytes Anti-Malware on a non-infected computer.
- After installation, open Windows Explorer and navigate to the C:\Program Files\Malwarebytes' Anti-Malware\ folder where mbam.exe is located.
- Copy the mbam.exe file to the Desktop and rename it to wuauclt.exe or explorer.exe.
- Save the renamed file to a usb flash drive or CD, then transfer to the infected computer.
- Alternatively, you can download a randomized renamed mbam.exe version (i.e. jdRjuT7Hk.exe) from here and use that.
- Another option is to upload the file somewhere so you can download it later to the infected computer.
- If you do not have access to another computer, ask a friend to email or upload a renamed mbam.exe for you and provide a link to download it.
- Place the renamed mbam.exe in the C:\Program Files\Malwarebytes' Anti-Malware folder on the infected computer, then double-click on it to launch the program.
- Check for database definition updates through the program's interface.
- Then perform a Quick Scan, check all items found for removal and reboot afterwards.
- Failure to reboot will prevent MBAM from removing all the malware.
- When done, click the Logs tab and copy/paste the contents of the report in your next reply.
Another thing you can try, if you cannot run MBAM or complete a scan in normal mode, is to perform a Quick Scan
in "safe mode
Scanning with Malwarebytes Anti-Malware in safe or normal mode will work but removal functions are not as powerful in safe mode. MBAM is designed to be at full power when malware is running so safe mode is not necessary when using it. In fact, MBAM loses some effectiveness
for detection & removal when used in safe mode because the program includes a special driver which does not work in safe mode. Further, scanning in safe mode prevents some types of malware from running so it may be missed during the detection process. Additionally, there are various types of malware infections which target the safeboot keyset so booting into safe mode is not always possible. For optimal removal, normal mode is recommended
so it does not limit the abilities of MBAM but sometimes there is no alternative but to do a safe mode scan. If that is the case, after completing a safe mode scan, reboot normally and try rescanning again.
Before performing a scan, don't forgot to check for database definition updates
through the program's interface (preferable method
) before scanning and to reboot afterwards. Failure to reboot normally
(not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs
tab and copy/paste the contents of the new report in your next reply.
If you cannot update MBAM through the program's interface and have already manually downloaded the latest definitions (mbam-rules.exe) shown on this page
, be aware that mbam-rules.exe is not
updated daily. Another way to get the most current database definitions if you're having problems updating, is to install MBAM on a clean computer, launch the program, update through MBAM's interface, copy the definitions (rules.ref
) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system. If you cannot see the folder, then you may have to Reconfigure Windows
to show it.
