Recently several issues have been reported to LANDesk Software regarding LANDesk Antivirus 9.5.
The root cause has been traced to defects in Kaspersky auto patch “B” released on 02/05/2013.
The following unexpected behavior has been observed:
- System slowdown/freeze,
- Unavailability of Kaspersky icon in tray

The problem can affect random machines running Windows XP SP3 and Windows 7 operating systems with LANDesk Antivirus 9.5 installed.
