Abstract
Aspects of the subject matter described herein relate to antivirus protection and transactions. In aspects, a filter detects that a file is participating in a transaction and then may cause the file to be scanned together with any changes that have made to the file during the transaction. After a file is scanned, a cache entry may be updated to indicate that the file is clean. The cache entry may be used subsequently for like-type states. For example, if the file was scanned inside a transaction, the cache entry may be used later in the transaction. If the file was scanned outside a transaction, the cache entry may be used later for requests pertaining to files not in a transaction. Cache entries may be discarded when they are invalid or no longer useful.
