I'm running Emsisoft Internet Security (2016) licensed for 2 machines (an Asus laptop and a Dell desktop), both Windows 10 64bit. No other AV is installed on the laptop. MalwareBytes and HitmanPro are installed on the desktop but not routinely running. Can't be sure of the exact version number but the Help file implies it's 11.0. (License was purchased March 2016.)
Both PCs asked to restart yesterday for the Emsisoft update. I restarted the laptop and it gave me the failed startup error, offering Restart Again or Advanced Options. I restarted, got the same choices, chose Advanced Options which included another choice to restart; picked Restart. Now it won't boot at all -- not even to the logo screen, so no possibility of entering Safe Mode for a System Restore. Screen is black and hard drive makes no sound.
I haven't restarted the desktop yet and needless to say I'm VERY unwilling to. (The laptop isn't that important to me but the desktop is absolutely critical to my livelihood.) What options do I have?? Can I even uninstall Emsisoft without risking it attempting to install its possibly-harmful update first?
Grateful for any ideas. Neither PC has had serious issues in the past.
