In the update of virus signatures of the anti-virus ESED-NOD32 made today almost all programs cause false positives. The problem has already been communicated to ESED and we hope that it will be corrected as soon as possible. We have verified that this antivirus is the only one that is causing problems. If you have any questions about it, you can process your files at https://www.virustotal.com
Unfortunately the anti-virus directly removes executables. We are sorry for the inconvenience that this may cause your clients and yourselves, but unfortunately we can not do much more about it, than waiting to be fixed as soon as possible. As soon as we know something else, we will inform you.
