My MacBook Pro has been slowing down a lot over the last few days and I have traced the problem to NAV. In the activity monitor it uses around 100MB when first started, but then steadily grabs more and more memory and never drops back - it’s gone over 2GB! Any suggestions as to how to fix gratefully received! Thanks,
Which component of NAV are you referring to? That is, what is the exact name of the item in Activity Monitor?
Hi - thanks for asking. It is ‘Norton AntiVirus’
Thanks, I'll look into this. Was it scanning at the time? Note that there's no reason to leave the application running between manual scans, though it shouldn't be continuously consuming memory anyway.
No - it wasn’t scanning. It does seem to follow a predictable pattern - I just opened it at around 85MB - after a minute it’s at 127MB, after 2 minutes 188MB, and it keeps growing… I have been quitting it. I think I just had it open to check the settings when I first noticed it hogging memory. Thanks for checking into it.
I am not able to reproduce this in my testing. I left NAV running overnight and it is still using roughly what it did at launch (about 28 MB Real Memory, 940 MB VM). If you can, the following may help diagnose the problem:
1. Download GatherSymantecInfo.zip from:
ftp://ftp.symantec.com/misc/tools/mactools/GatherSymantecInfo.zip
2. Expand GatherSymantecInfo.zip using Apple’s archive utility (other programs may not expand with proper permissions):
/System/Library/CoreServices/BOMArchiveHelper (OS 10.4)
/System/Library/CoreServices/Archive Utility (OS 10.5/10.6)
3. In GatherSymantecInfo folder, double-click GatherSymantecInfo.command.
4. When prompted, enter your computer user password.
5. When prompted for a subscription key, simply press return.
6. Attach the generated SymantecInfo.txt file to your reply.
7. If SymantecInfo.txt is too large to attach, you may attach SymantecInfo.zip instead, but you'll need to first rename it to SymantecInfo.txt (or anything with the txt extension).
