"Malware 'Unscannable' was detected and blocked in a download from ocsp.digicert.com"

Hello and have a nice day

we had a short power failure yesterday and since then I have this error message in the event log every second:

messageid="08001" message="Malware 'Unscannable' was detected and blocked in a download from ocsp.digicert.com" log_type="Anti-Virus" log_component="HTTP" log_subtype="Virus" status="" fw_rule_id="16" user="" web_policy_id="0" policy_name="" virus="Unscannable" url="http://ocsp.digicert.com/MFEwTzBNMEswSTAJBgUrDgMCGgUABBQ50otx%2Fh0Ztl%2Bz8SiPI7wEWVxDlQQUTiJUIBiV5uNu5g%2F6%2BrkS7QYXjzkCEAxq6XzO1ZmDhpCgCp6lMhQ%3D" domain="ocsp.digicert.com" src_ip="192.168.100.35" src_country="R1" dst_ip="93.184.220.29" dst_country="GBR" protocol="TCP" src_port="50781" dst_port="80" bytes_sent="279" bytes_received="799" user_agent="Microsoft-CryptoAPI/10.0" status_code="500"

Also, incoming mails are no longer scanned for viruses and spam protection does not work anymore.

For the time being I have set the protection on scan failure to 'Allow' and also had to deactivate the caching, so that I don't get any more error messages for the time being.

With best regards

  • This sounds like a corruption issue. That said, this particular error message ("Malware 'Unscannable' was detected and blocked...") shows up once in a while for me and as far as I can tell nothing is corrupted on my system -- everything basically works except an "Unscanable" every couple of months.
