This is Mike from the Norton Authorized Support Team.

First, I wanted to let you know that Symantec has created a tool to resolve the issue with the “AppSvc32.exe” process consuming system resources. Using Internet Explorer, click on the link below and run the tool.

Fix issue with the AppSvc32.exe process and Norton AntiVirus 2007

I also wanted to let you know that this particular issue only affected NAV 07, and as long as you still have a valid subscription to Norton AntiVirus, you are entitled to a free update to Norton AntiVirus 2009, which I highly recommend. The new version of Norton AntiVirus contains many new and enhanced features and consumes very few system resources.

To update, please visit the Norton Update Center at the link below. Please NOTE, while this process will update you to the 2009 version of Norton AntiVirus, it will not extend your subscription.

Norton Update Center

Once the installation is complete, launch Norton AntiVirus 2009 and manually run LiveUpdate to ensure you get the latest program and definition files applied. This process will also invoke the new “Pulse Updates” feature which will check for and install new definition files in the background every 5-15 minutes.

When the updates have been installed, restart your computer and then open Norton AntiVirus and complete a “Full System Scan” to check for infections.

Thank you,
Mike
