Resolved issues
Here is a list of issues from previous releases of the software that have been fixed.
Issues resolved in this release
These issues were resolved in the VirusScan Enterprise Patch 4 release.
1 Issue — McTray.exe stopped working when logging off or during upgrades. (Reference: 753122)
Resolution — Fixed a timing issue in the VirusScan Enterprise plug-in.
2 Issue — Windows Server 2008 Server systems did not delete session when users logged out, so system resources
continue to be consumed by inactive sessions. (Reference: 778101)
Resolution — Revised the mfehidk.sys driver to eliminate a dependence on resources that might not be freed when a
user logs out.
3 Issue — Margin settings are altered (reset) when viewing settings on localized Outlook version on English operating
system. (Reference: 782155 )
Resolution — VirusScan Enterprise Outlook Email scanner now writes registry data using installed locale instead of the
user locale format.
4 Issue — Command-line On-Demand Scans ignored the /logformat switch, and instead wrote logs in the default format
(UTF-8). (Reference: 786061)
Resolution — The /logformat settings are now used and scan logs are written in proper format.
5 Issue — Bugchecks could occur in mfehidk.sys. (Reference: 797573, 795174)
Resolution — Modified mfehidk.sys to ensure that context data is passed between pre-operation and post-operation
handlers in a manner that doesn't cause invalid memory references.
6 Issue — ePolicy Orchestrator administrators could not reliably determine the status of the On-Access Scans on client
systems. (Reference: 820636)
Resolution — VirusScan Enterprise now reliably reflects the status of On-Access Scans on the client system
7 Issue — McShield timed out after a DAT update. (Reference: 825043)
Resolution — Resolved a deadlock condition between the pause for update and trust validation.
8 Issue — On systems with large amounts of RAM and multiple cores, On-Demand Scans quit partially through scan
activity. (Reference: 825623)
Resolution — Repaired a memory leak in the On-Demand Scan process. The read activity no longer increases memory
