Report Steam won't start after update in Emsisoft Anti-Malware Home Posted October 4, 2018 30 minutes ago, ahuman said: Same issue on Windows 7 64x, excluding the folder changes nothing. I have to disable protection to even start Steam. Dammit I'm pissed, I thought Steam somehow broke itself so I uninstalled and reinstalled, without backing up my games (don't have the drive space) and have lost over 500GB of games including carefully modded games with over 200 mods applied with specific load orders that I can't remember. How could you disrupt such a major program like this and when will there be a fix? Same thing here. Windows 7 x64, went and uninstalled Steam first.
