Exchange 2007 first storage group database will not mount

The anti virus program detected a virus and deleted the file. Unfortunately the file was E00.log in the first storage group. The event viewer reads :

 'The file 'C:\Program Files\Microsoft\Exchange Server\Mailbox\First Storage Group\E00.log\E00.log\photo_P0809201181992884.jpg______exe contains the generic malware a trojan. Undetermined clean error, deleted successfully

Since then i cannot mount the database. eseutil /mh reports a dirty shutdown. I tried using the eseutil /r but it says i need to use the /A switch. The information store back up has an exclamation mark next to it so i don't think that's any good.
Can someone tell me please what the command i need to put in which includes the /A eg; eseutil /r E00 /a ???

You should always exclude your Information Store for anti virus solutions.

I've not heard of /a

check this:

I know, I recently took over looking after the IT requirements of the company and with getting to grips with the network etc; didn't even think to look at what the av was scanning. First thing i did was exclude the information store.
I read somewher the /a is a switch that can be used in Exchange 2007 and is used with the eseutil recovery option.
Anyways I skipped the recovery after many failed attempts and did a repair instead. So far so good, got a clean shutdown and just defragging the database.

move all files except the .edb file (your database) to another folder. After that it should mount normally. You can find them in the installation folder of Exchange, inside the Mailbox\\First Storage Group folder.

It's all done, I repaired the database, defragged it, and I had to move all the files except .edb file from the first storage group and put the in another folder..then it mounted and all mail is now working.
Time for a quick back up ;-)
