I'm happy to help - maybe I can reinstall the beta if there is a workaround to this or once it's fixed?
Unfortunately we need antivirus software that keeps logs for 12 months to comply with PCI - and I'm not sure if Avast will meet that requirement even when the final release is available. My plan therefore was to keep looking at the options available - but if someone can tell me where the log files are stored (for the real-time shield) then I can set up some automated backup.
I'm quite wary of antivirus software generally - I tried Intego's Virus Barrier a few years ago and it kept causing kernel panics, then I tried Sophos last week and it kept freezing my MacBook Pro, so I uninstalled that. Avast is definitely the most promising I've tried so far - and it's only a beta!
