Re: Mcshield.exe High Virtual Memory Usage

Thanks I notice another poster had no vmware installed so I wonder if you removed any other program around the relevant time period? Do have or had Adobe Air?

That said was your issue only memory use or cpu as well by mcshield?

Re: Mcshield.exe High Virtual Memory Usage

I have Adobe Air on my PC right now.  The issue was both with shield.  It would be top dog in memory use, the CPU would get to 100%, the fan would be screaming and I would have to reboot.  Go back to about the third week of June 2011, and that will begin this occurrence for me.  I documented all this from that time through mid-December 2011, as did others.

By the way, what came out of the Monday call?

Re: Mcshield.exe High Virtual Memory Usage

Yes coxdavi - you are right - it was around May/June last year....after a period prior to that of relative calm.  Increasing your Ram from 512 sounds like a very good idea! I didn't think you could even run Windows any more on that little

Creator - I don't understand your post.

Hi islandgirl,

What is the operating system you are using, that is installed? Are you running the Anti-Virus 2011 Version? That version contains two Core Anti-virus products. Meaning Real-Time Scanning can't be Shut-off. McShield is constanting running in the background, which I attempted to show you via the PrtScrn Snapshot.

Open up McAfee Security Center. Look at the options for Anti-virus. Look at About McAfee for Anti-Virus as well.

Re: Mcshield.exe High Virtual Memory Usage

I am using Windows XP.Pro 2002 SP 3

I am using Virus Scan Plus and Securty Center

VS Version 15 - 15.0.294

SC 11, 11 .0.654

I am well aware the Mcshiled was ruinng constantly in the background.

Are you a Mcafee technician?

Re: Mcshield.exe High Virtual Memory Usage

PS On this version I have the option to turn off real time scanning.

I am disinclined to do so however - if it is designed to enhacne my protection, why shold i reduce the level of protection to produce a work around to an existing problem?

Hi islandgirl,

     Do you have a Router, between you and a Cable Modem?

     Turning Off Real-Time Scanning does not turn off McShield.exe, which was what I tried showing you in that PrtScrn Snapshot.

Re: Mcshield.exe High Virtual Memory Usage

Hey, just wanted to add some to this.

Real-time scanner performs a specific function. It reads/scans each file and process as it tries to write to or read from the computer. What this means is that you essentially have 2 types of virus scan. One that runs all the time, constantly observing behaviors and comparing files to known threats, and a manual scanner that you tell to start (or run on a schedule).

If you disable the real-time scanner, you open a hole in your security. Yes, a router will provide you protection from, for example, worms (they tend to scan for open ports on a computer, and a router tends to - by it's nature, and also by settings you can change - do something called port forwarding). But a router won't protect you from a file you download by choice which happens to contain a trojan or other malware like a keylogger. When you download that file and try to run it, the real-time scanner is what scans it for threats. If you disable it, you put yourself at risk for trojans you self-selected; easily the most common type of home user infection.

So yes, you can disable real-time scanner, but it is highly not recommended by McAfee.

Regarding the high CPU usages we're seeing, this isn't the same issue you were seeing in May or June. This is the problem.... any number of variables on any computer has the potential to cause a problem like this. It's entirely possible (and totally likely) that the problem causing this result on Coxdavi's machine is totally different in every way from the one on Islandgirl's machine, they just result in the same CPU excess. So what does this mean, from a support perspective?

It means we've been unable to duplicate them in a lab environment. We've found other things which could cause this problem, and we fix them as we find them (which is probably why the problem went away, then came back again - we fixed one thing, but something new came up). It's very difficult to troubleshoot as well, as each computer potentially has a different issue. Add to that the fact that easily half of these types of issues end up having nothing to do with McAfee, but rather some other application or piece of hardware interacting questionably with McAfee (example - you had Norton 360, then uninstalled it  and installed McAfee, but Norton 360 left a bunch of embedded keys in your registry) Or maybe you have an older computer with the minimum amount of memory installed. That would certainly slow things down. You end up with a massive list of possible variables, each one requiring troubleshooting.

Or maybe there is genuinely something going on here, some common thing. But it's a process of elimination to find that thing, and one of the most time consuming types of troubleshooting to do - especially if the high CPU just bogs down the computer instead of totally crashing it. If it crashed it, we'd be able to possibly get a memory dump and find something that way.

My purpose in posting this is really just to try and have as much transparency in what's going on here as possible, try to explain the concepts we're working with here so you're able to take an active part in this process, and to let you know that we're trying to get something solid to move forward with... and to ask for understanding if it seems like we're asking a lot of questions of each of you. The mods are on the right track, trying to find commonalities to make that list of variables smaller and more realistic. Additionally, myself and the Tier 3 engineers are keeping an eye on this and working with the mods to try and get a breakthrough. Thanks Thecreator for trying to pitch in and help out, it's much appreciated! And thanks Coxdavi and Islandgirl for keeping this on the radar. The mods are keeping the issue alive in our engineering meetings too.

Re: Mcshield.exe High Virtual Memory Usage

Hello Spyron!

Fear not - I had no intention of disabling anything and I was about to post exactly that for all  the reasons you articulate so clearly

No one has picked up on my comment about McSvHost.exe crashing all the time - which is new - and no , nothing else in my environment has changed - except I have a new power supply 🙂

Re: Mcshield.exe High Virtual Memory Usage

Ugh. Don't say power supply. I just had one go bad and I had to buy and build an entire new computer. *grumble*

When your mcsvhost crashes, is it at boot or shutdown? Or just randomly? Have you noticed it crashes more when you're doing certain things/running certain apps?
