Clamav stops in /var/log

[George Hare]

ls -l /var/log

- J<> Is /var/log/lastlog huge?  It's a sparse file so it doesn't take up
- J<> any disk space, but running through it byte by byte isn't going to be
- J<> quick.

ls -l /var/log/lastlog produces - 1 root root 1254130450140.
Can I skip the scan of /var/log or are there security issues involved here?

Many thanks,
