ClamAV Signature Update fails
Question / Problem
ClamAV does no longer update its signatures. Even starting freshclam.exe manually fails.
Answer / Solution
This problem can be caused by the Windows Defender or other third party anti virus solutions. Add the following paths to the exclusions:
C:\ProgramData\JAM Software\ClamAVInABox\Signatures
C:\Program Files (x86)\Common Files\JAMSoftware\ClamAVInABox\sanesecuritydbtemp
