It would be undesirable for a virus scanner to decide to move documents out of the TRIM store into its quarantine folder (or delete them) because it thinks it's identified a security risk. Users would get errors, TRIM administrators would be scratching their heads, a call would be logged with HP for the error messages, and a lot of time would be spent figuring out why documents mysteriously disappeared out of the TRIM store. Guaranteed IT would blame TRIM before their virus scanner. In theory all TRIM documents are virus scanned at the client before being catalogued.
If virus-scanning the TRIM store it's important the virus scanning software is configured appropriately to avoid this sort of effect.
