Error when launching any game (was working fine)

Everything has been working fine until today. I tried to launch a PS2 game, got a black screen, then it returned me to the games list. After that, trying to launch any game from any console gives me an error that windows cannot find emulatorlauncher.exe. I did a fresh installation and still get the same error.

Hello,

this is definitely an overzealous antivirus that deleted the emulatorlauncher.exe file, so you need to authorize the file.

I was able to find it in my (Avast) virus locker and restore the file with an exception, but another copy remained in my virus locker that could not be deleted or restored. I put it into passive mode and did a fresh install of RB. It will now open games, but every game on every emulator runs super slow with broken sound.

I can't help you with performance issues. but why redo an installation, just for a missing file?

It didn't work at first, removing the file from my virus locker and restoring it didn't make the error come back up, but it didn't load games either, just a black screen then booted to games list. I did a fresh install to make sure everything was fine.

Before all of this happened, performance was not an issue. Everything including more advanced systems like ps2 and gamecube/wii were running smooth up to 1080/4k60. Now everything, even simple emulation, is broken and unplayable. I have no idea what happened, but the performance issue isn't because of my hardware, I'm running an amd 3900x, 2080ti, 64gb ram

Realy strange...

Avast is shity, use Defender supplied with windows 10, is free, and is the best anti-virus.
