Emsisoft Anti-Malware Unexpected installation problem windows 7
Some people did in the past because on a very small number of systems the first versions of the update ended up in a boot loop. If you still can't install the update, you can uninstall EAM/EIS and download a complete setup from here:
Emsisoft Anti-Malware:http://dl.emsisoft.com/EmsisoftAntiMalwareSetup.exe Emsisoft Internet Security:http://dl.emsisoft.com/EmsisoftInternetSecuritySetup.exe Then perform a reinstall. The new setup may complain about an Emsisoft product already being installed. For cases like these, we provide a special Emsisoft Clean utility, which will search for any Emsisoft Anti-Malware and Internet Security remnants on your system and remove them for you. Please note that this powerful tool is not intended to be a replacement for the default uninstaller shipped with our products. So only use it after you tried the shipped uninstaller. You can download Emsisoft Clean here:http://tmp.emsisoft.com/fw/emsiclean.exe After you finished downloading, simply start the program. Read the disclaimer carefully and click "Yes" if you agree. The program will now scan your system for any remnants and display a list of everything it found. It usually is safe to just remove everything except folders. Emsisoft Clean can't know if the folder still contains any data you may need later, which is why those entries aren't checked by default. Emsisoft Clean is capable of removing the folders as well, but before you enable the check box in front of any folder entries, make sure you carefully checked their content for valuable files. Once you finished your selection, simply click the "Remove selected objects" button. The tool will eventually ask you to reboot. Save all your open work and perform the reboot as requested. After the reboot, you should be able to install Emsisoft Anti-Malware or Internet Security just fine.
install Windows Updates. Windows 7 with Service Pack 1 doesn't include support for SHA2 certificates, and currently, the Emsisoft Protection Service is only signed with a SHA2 certificate.
At the very minimum, you need to have this update installed on Windows 7 (along with Service Pack 1 of course) to add SHA2 certificate support to Windows
