AppSvc32.exe slowing down my computer.

My computer has just slowed to a crawl. I looked in Task Manager and noticed that this file was using 76000K of memory. I gather it is a Symantec file but can't find the Symantec Shared Prog folder. What exactly does this do that requires so much memory? And why can't I find it? I notice that it is now using just 5000K of memory and the computer is back to normal. I have Windows XP and NAV 2007. Any help please.

AppSvc32.exe slowing down my computer.
Open Norton Protection Center
Click on Norton AntiVirus tab at top
Expand "Settings" and scroll down to bottom for Additional Options -> Virus and Spyware Protection Options
On the left-hand side of the screen that pops up, click on General Settings under Manual Scanning
Uncheck the second item, which should be "Scan active programs and start-up files"
Again, on the left-hand side, click on General Settings under LiveUpdate
Uncheck the second box there, too. It should be "Run quick scan whenever protection updates have been received"

You are NOT the only one!

Norton's Internet Security 2011 slowing down my computer

I tried what you said, but I have Windows 7 64 bit and the above named Norton's program. I couldn't find the same settings and am not extremely computer literate. Can you tell me how to change the settings on Norton's IS 2011?

Solution to AppSvc32.exe issue

Hi Judesman,

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,

Michael York

Solution to AppSvc32.exe issue

Your description is wrong. The AppSvc32.exe issue is also present in Norton Internet Security 2007. After installation of NIS, AppSvc32 begins to download a larger than 70MB file until the system crashes. This may eventually erase the BIOS or write into the Graphics controller and damage the High Voltage Inverter for the CCFT LCD backlight. I hope, that - under these circumstances - a NIS 2009 upgrade will be available.
