A core and a half of CPU is being used by freshclam which is hanging, even after restart. I have stopped it using killall but after restart conky shows freshclam taking up 50% of CPU. I opened clamtk and set updates to manual, and updated manually, but the issue still persists. Anyone know what the issue is? In Mate 18.04.2. Thanks.
I am having a similar problem.
I use 18.10. Updated Ubuntu-MATE on 3/9/19 for first time in a week and the ClamTk definitions update hung for first time after that. I tried the update again and it hung. I removed and reinstalled ClamTk and the definitions update hung again. I tried Clamfresh in terminal and the error message told me something like my ClamAV was outdated. I never loaded ClamAV a few months ago when I started using ClamTk. I think ClamAV was listed when I launched "Software" looking for virus software options a few months ago, but it's not there now.
I'm not computer literate enough to try to download ClamAV from the Ubuntu repository.
I removed ClamTk again, rebooted and reloaded ClamTk. I'm not sure that made a difference, but then I tried to update again and let it run for about an hour. It updated the virus definitions.
