It's difficult to give you a firm answer without testing using exactly the same software and material.
I would say try things and see. McAfee is geared to throttle back when CPU-intensive applications are running in any case.
You could perhaps make sure that nothing will run while you are working with these applications.
Double-click the taskbar icon to open SecurityCenter
Click Advanced Menu (bottom)
Click Tools (left)
Click Start under Task Scheduler (right)
Delete the Defragmenter and Quickclean tasks.
Then click Configure (left)
With SecurityCenter highlighted (top left)
Click Advanced (right)
Click Update Options (left) and adjust settings there.
You can also adjust Alerts there.
Now highlight Computer & Files (top left)
Click Advanced (right)
Click Scheduled Scan (left)
Adjust settings accordingly.
thank you Peter!
For its real time checking I think McAfee places itself in the file system read/write path and does some scanning on every read and/or write? Such would be very expensive during heavy IO of course, so that is my main concern. I dunno if this expense is avoided by temporarily turning off real-time scan, but that would seem the right way for the product to behave.
any other experience/suggestions with this is appreciated!
Yes I suppose it's true that any file in transit will be scanned in real time. You could temporarily disable VirusScan if it causes problems.
To temporarily turn off VirusScan do the following:
Double-click the taskbar icon to open Security Center
Click Advanced Menu (bottom left)
Click Configure (left)
Click Computer & Files (top left)
You can disable VirusScan in the right-hand module and tell it for how long
Can someone please put this as a sticky?, a bulk email, in BIG BLOCK letters, that this is how you disable it? Put it at the top of the forum listings. PLEASE.
I mean, make it available to (staple to forehead-reverse first) anyone doing level-1 helpdesk support, who are reading from a script, whose command of english is secondary, who are representing McAfee, dealing with users who have more of a clue than they themselves?
Or perhaps a nice annoying pop-up, or a link somewhere in the read-me, or the about: link, or ANYWHERE someone could find it that they didn't have to google the support forums, instead of clicking links to get there, then, have to create an account to find it, I swear to god it's like one of those endless loop tech support phone calls from Sierra's hint-line at $9.95 a minute.
May I suggest if you sticky it, select a title representative of the problem and the fix, not a generic description like this thread. "Balancing performance and security" is like saying juggling viagra pills and condoms. Nobody wants to know which one you swallowed.
And who's brainless idea was it to get rid of exceptions of folder/applications to begin with? Drives?!? You can only exclude entire DRIVES? No more protected programs?
This is enough to make me re-evaluate the comfort, stability, and security of Norton (This is sarcasm. Do not treat it as honest willingness to drink Norton Kool-Aid). I might prefer the weekly ghosting, but I'm actually looking towards virtual desktops at this point for survivability.
I don't even want to go into what these brainless script-monkeys told me to do to resolve my "I can't exclude a program from the real-time scan list" issue.
There are no stickies with this new host, but you have good points. We have asked for those abilties to be re-introduced for years and years, believe me.
The facility to exclude files/folders and drives from an automatic scan was taken away from the consumer products years ago. It still applies to Enterprise products, however.
You can tell a scan to skip a file once it has reached it if, for instance, it is taking too long to scan it.
We hear you and always pass these suggestions on, but the powers that be don't agree with it, and that's been that so far but we are still bugging them.
The new products now in beta testing should prove to have less of a footprint.
