This morning, everyone got kicked out of email and i checked event viewer to find that norton a/v detected the netsky virus in edb.log and deleted it. Exchange tried to recreate the edb.log and remount to store to no avail. I tried to do a backup of the edb.log file from a few hours before it was deleted and the store still won't mount.
Event Viewer logs:

After unsuccessfully trying to copy a backed up edb.log and restart the store, i copied the priv.edb to a server with enough room to run an eseutil /p on it. (not enough room on the mail server and without correct log files anyway, didn't think a soft recovery would be possible)
So now i've run the eseutil /p and it found many inconsistencies and I guess repaired them so now i'm running an eseutil /d (as per an article I read on here)
I plan on running the (isinteg -pri -fix -test alltests) next for good measure but am not sure what to do afterwards.
I have deleted all of the log files and edb.chk from the mdbdata folder (as per a suggested solution from microsoft) but need to know the proper way to remount the defragged/checked priv.edb
Not sure where to go from here.
