As per our previous announcement ClamAV file signature retirement has been implemented.
Users may notice that file sizes are much smaller today as a result of the signature retirements.
After we retired impacted signatures our download file sizes are now:
bytecode.cvd: 275 KiB
main.cvd: 85 MiB
daily.cvd: 22 MiB
Our team is continuing to monitor alerts and the current threat landscape and we are committed to reintroducing retired signatures as needed.
For more detailed information on the ClamAV signature please see our previous blog post.
