problem with seeding exchange 2010 database

I have the following errors on one of 12 databases in our enviroment: After a trojan Horse was detected and quarentined, the replication to the passive database was broken. Also backup is failed and will not complete successfully, that results in not purging the logfiles for this database.

When trying to fix the replication with a full reseed, I get the following error:

MDB12
Failed

Error:
A source-side operation failed. Error An error occurred while performing the seed operation. Error: Communication was terminated by server 'SRV02': Data could not be read because the communication channel was closed.. [Database: MDB12, Server: SRV01.domain.local]

Exchange Management Shell command attempted:
update-MailboxDatabaseCopy -Identity 'MDB12\SRV01' -DeleteExistingFiles

When performing this operation from EMS the following error occurs:

[PS] C:\Windows\system32>Update-MailboxDatabaseCopy -identity MDB12\SRV01

All other databases are replicating als they should be.
I fear that when I dismount the database and remount it again, it will fail, and not be mounted again. without a passive copy or a recent backup, this will be a big issue.

Anyone a hint or solution for this?
