We’re experiencing an issue with our code-signing vendor that caused prior builds of Borderless Gaming to stop working.As a temporary fix, we’ve removed the EV code-signing signatures from BorderlessGaming.exe and appcontainer.exe. Because these files are temporarily unsigned, Windows may display an “Unknown publisher” warning and some antivirus products may flag them.We have no indication that Borderless Gaming has been compromised; the alerts are a consequence of the missing signatures. However, if you are not comfortable adding an antivirus exclusion for our app, do not disable your security settings—uninstall Borderless Gaming and wait for the next release.Code signing will return once the vendor issue is resolved. Thank you for your patience.EDIT: Kaspersky will fix the false-positive
