AV Quarantined A Log File - Can I just restore it?

I'm running Exchange 2007 SP/1 on a CCR cluster. A setting got changed and the exclusions for the AV were ignored and a log file got Quarantined. Can I just restore the log file from quaratine?

The database seems fine but it says it in a dirty shutdown state and backups wont run because it can not find the log file - outside of that everything seems to be OK.

the AV is Mcafee 8.7

These are the errors in the application event log:

Yes just restore the log file from quarantine and make sure the correct exclusions are in place again.

Put the correct exclusions in place first and then restore the log file

You van then do "eseutil /ml e02" to check all the log files to ensure you have them all and once that passes either just mount your stores or do "eseutil /R e02" and your DB should go back to being CleamShutdown
