Symantec AntiVirus Corporate 10 - Resource Hog?

Recommended Posts

There's a bug with version 10. If you look at the task manager, you'll see doscan.exe chewing up the cycles. This is caused by a pre-configured schedule scan at boot-up. If you go into the configuration menu, on the left-hand tree, you will have the chance to delete all the scans. Problem solved.

I tell people to quite running as admin/root and the vaste majority of viruses and other malware do work.

I have only seen one virus on any system that I have ever used. It was an early macro virus.

I run ETrust on computers that ras in from because it is required to connect. I always suggested disabling realtime scanning and I think scheduling av to run periodicaly is more than enough.

I have not see any anti-virus program stop any of not recently. I know of no instances of av finding any of the notable worms or spyware in the last few years.

I think running SpyBot periodicaly is far better protection than Norton.

Yeah thanks I noticed that default scan job as well a few days ago. Haven't restarted to test it yet though.

I have had many emails with binary attachments. However, none of them has infected my machine. Real-time virus detection is for idiots.

The reason I run a virus scan once a month is because I download software. Never trust any EXE/ZIP.

And you're being bloody arrogant.

It's according to what he meant.

My point being:

Go into any good ol' "warez" or "erotica" newsgroup, and just start downloading everything. Let it go a good day or so, downloading several Gigs...

Now, your "real-time" NAV will just sputter along, slowing your system and drive access times, but won't make a single complaint about what you are writing to your drives.

NOW, do a full system scan, and scan the folder you just saved all that warez/porn to...

I'll make a $5 bet it finds at least 10 trojans/virii/etc...

Now WTF isn't a "real-time" scanner stopping that from even being written?

Sorry, I don't trust the logic whatsoever of AV software that will allow virii to be written on my system, but will only stop it from being run. I don't even want the potential for this stinker on my system.

What if I decide (as many installers suggest) to temporarily disable AV a moment?

That's why there are conspiracy theories surrounding Norton...

So, in my experience, I agree. Real-time NAV cannot be trusted in any way whatsoever. The way Norton implements it is idiotic...

You snipped the context, so I will repeat it:

Anyone who gets a virus from email is an idiot. You do not open an EXE/ZIP attached to a message. Don't blame anyone but yourself if you do.

That DOSCAN.exe is a startup scan that will scan all startup files after every reboot. Remember this is CORP version and will incorporate these scans for security purposes since these PCs will be left on all day and not rebooted alot. And even so, on a new machine the scan isn't so bad but on a slow machine i can see it taking a little bit. But after the scan is done, it will stop so if u are patient it will go away and assure you that you safe. On my pc that startup scan actually scans about 16000 or so files whereas a full scan will do about 360,000.

To summarize, it is not a bug but a security feature that can be disabled if you wish.

Sorry for double post !

As far as memory the doscan.exe does use 100 Megs of RAM on my machine. I have 1 GB of RAM with a 1 GB Pagefile. But after the scan completes, naturally it releases the memory and it becomes available to my system again, no worries.

Good Day to all

Oh come on. Some people like to zip file to email them. Are you saying this is a bad practice? It's easy to say not to use a feature of a program. I might as well not drive a car because I could possibly have an accident :rolleyes:

You obviously want the 64 bit version of Corp NAV 10

Get, bittorrent.

Purchase, probably not possible for a single user.

Why no one search Symantac.com (DoScan.exe causees high CPU usage), they are still doing the investigation and they provide a workaround.

Had you read the thread, you would have seen that two posters have already done so and recommended the workaround... :rolleyes: (PS. It is www.symantec.com)

Yes, it is "www.symantec.com".

Yes, the reason I post this post is because I go thru the thread and find out that if someone just post the symantec's document then we don't need to guess around.

I just wondering when symantec going to release SAVCE 10.0.1 ?

By the way after trying SAVCE 10.0.1, how you guys rated the anti-spyware or their "Security Risks" function besides the Anit-Virus function? I try it on hotbar on my lab and looks pretty good.

Symante knows of this problem with doscan.exe and has issued a work around there is no fix as of yet...

DoScan causes high cpu usage

SAV 10 Corp is not as resource heavy as it's Norton personal counter parts. We are running it on p3 500's with 128 mb ram. After applying this workaround we have seen significant improvemnt.

I just uninstalled Norton Internet Security for a personal client who was running it on a Gen 1 Pentium, took his computer (98) 20 minutes to boot. After the removal it works great!

Try free av for personal use www.avast.com I use it and love it loads of features for no $$$.

I have installed this after removing Norton Internet Security and found what Norton missed.

Hi, has anyone else noticed the extremely high CPU and memory usage by Symantec AntiVirus Corporate Edition 10? I've installed the client on a few computers now and I noticed RTVSCAN.exe and DOSCAN.exe using very high CPU loads constantly until I terminate the process, and the RAM doesn't seem to be any bit better. It can use over 150MB of physical RAM.

Any solutions apart from downgrading back to 9? At first I thought it was just an oddity but I realize now that every single computer I've upgraded/fresh installed it on gives the same symptoms.

Hi, I have already installed Symantec Corporate 10.0.1 and the same problems exists in that rtvscan.exe climbs over 40Mb of ram usage..... the registry fixes disable the ability to do a quick scan. Fresh install of Clients make no difference, perhaps 10.0.2 will have a "real" fix!!
