This is the first time that an update of LibreOffice - downloaded some minutes ago: http://donate.libreoffice.org/home/dl/win-x86/4.3.1/de/LibreOffice_4.3.1_Win_x86.msi - can only be installed after stopping my virus shield. This must be a bug.
Well, file a bug against your virus shield then instead?
Our official installers are even digitally signed, so if your antivirus is alerting you, then itβs a false positive. Report it to them instead.
