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.
Please download Malwarebytes Anti-Malware
, save it to a flash (usb, pen, thumb, jump) drive or CD, transfer it to the infected machine, then install and run the program from 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 in some cases, there is no alternative but to do a scan in safe mode.
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 it is not "Write Protected
". Some flash drives have a switch on the side which could have accidentally been moved to write protect.
You will also need to, manually download the database updates
, save and transfer them as well. After installing MBAM, just double-click on mbam-rules.exe
to install and update.
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.
