Ubuntu – ClamAV : freshclam hangs and uses 100% CPU

16.04antivirusclamavmalwareupdates

I try to update the ClamAV database by running freshclam. The daily-*.cdiff is downloaded successfully, but then the process hangs.
The CPU is maxed out at 100%, but the update just will not finish. I canceled the process with Ctrl+C after appr. 10 minutes. Here is the output from my update attempt:

# freshclam
ClamAV update process started at Tue Nov  8 00:15:57 2016
main.cvd is up to date (version: 57, sigs: 4218790, f-level: 60, builder: amishhammer)
Downloading daily-22474.cdiff [100%]

Did anyone else observe this behavior? Is it a bug or is my system not properly configured?

PS: I am using ClamAV v0.99.2 on Ubuntu Mate 16.04.

There was a large Cdiff published for older users recently. Try deleting the daily and daily cdiffs* and re-running Freshclam. Let me know if that works.
