Symantec AntiVirus Performance - Tilted Forum Project Discussion Community

trache · 05-26-2006, 07:27 AM

Searched the forum, found nothing.

I have a user who has asked me if our corporate Symantec AntiVirus 10.x has a featured to "cache" already-scanned e-mail attachments in Outlook (We do not have MS Exchange and instead POP3 our e-mail from our host). His computer is very low powered and it's causing him grief.

From all of my dealings with SAV, I don't think this isn't possible. Each time they bring up the e-mail in Outlook, the desktop NAV scans the e-mail.

This brings up another question for those of you who do use SAV: How do you increase performance on your workstation PCs? I tend to:

Limit scanning to a list of certain file extensions (which seems to grow daily!)
No network scanning (We have the server scan itself)
Only scanning certain drives

Anything else I could do to A) cache already scanned e-mail attachments or B) Increase real-time scan performance in general?

Thanks.

I might be missing something here.... but if its already scanned, why does he not just save the file on the harddrive. The next time he needs it, he won't have to access the already scanned e-mail. He can then either delete the e-mail or keep it for backup.

tres:

Everytime the file is accessed, NAV (the desktop installed client) will scan it with real-time on-access scanning. But I brought up that point as well to my colleague as well (I'm the IT guy)... It's Outlook that's slow after all.

I'm wondering if there was method of telling NAV not to scan it again somehow (which I strongly, strongly doubt and obviously wouldn't recommend to anyone if this method did exist).

In the end, I think he's just whining. :-) Now, I can't simply upgrade his computer yet - it's not in my budget.

Is there a particular file type that he frequently recieves? are ALL the files he's accessing downloaded from outlook? If he frequently or mostlyrecieved .doc files for example, you can exclude that extension from autoprotect. It will still be scanned on intial download from the pop server, and anytime he opens a doc file nav will not initiate.

If your worried about the general "auto protect" from slowing down the system, then disable it, or have it only scan certain types of files. Sure.. There is a security risk. But everything is Cost/Risk/gain. You can still schedule daily scans of his system after business hours.

Unfortunetly NAV takes up alot of resources.... hope i was of some help
