You experience the following symptoms when you are using Microsoft Forefront Client Security.
In an environment that has many managed client computers, you request an on-demand scan from the Forefront Client Security Dashboard. However, the client computers take many hours to receive the scan request and to start the scan.
During this period, the ScanNow
button on the Forefront Client Security Dashboard remains unavailable. Additionally, the following notification appears in the notification list:
When the Forefront Client Security Management Service tries to import the anti-malware signatures into the Microsoft SQL OnePoint database, you experience one of the following problems:
Symptom 1 occurs because Forefront Client Security calls each computer individually to run the scan when Forefront Client Security sends a scan request. In addition, Forefront Client Security calls the Anti-malware (AM) scan and the Security State Assessment (SSA) scan as separate tasks. After you apply this hotfix, the individual scan requests are handled in batches to increase performance.
Symptom 2 occurs because of the number of characters in various entries that are in the signatures files. After you apply this hotfix, the entries are truncated to 64 characters.
