AVG Cache Server Process AVGCHSVX.EXE

AVG Update to V9.0

Hello,
This is an observation rather than a solution - updated AVG Free today 3 November 2009 at about 11:30. The AVG cache program ran at varying cpu load with lots of disc thrashing for about 8 hours. It has now stopped on this Toshiba Satellite Pro A300 running XP-Sp3 - thank goodness. AVG could have warned about this, couldn't they?
cheers

Took me 15 hours+ to scan through ~1TB data, so, it's not that strange, beside, it was on his laptop...

There is a thing called "Full computer scan" in Norton, and it worked the same way.

IDK, this is behavior that I expected (I recently upgraded to AVG 9). It could just be me though...

The cache server is used to help speed up the AVG tests and resident shield to limit memory useage and so the testing doesn't take as long. It allows AVG to know what has been tested previously so it doesn't need to retest them unless they are changed or updated. In short, it optimizes AVG.

It worked the same way, i didn't say it the same thing.

True, it could be a first for AVG. But I what I meant is that I would expect this behavior when I clicked on the "Optimize Scanning" option or whatever it's called (it was a couple days ago).

No, it's just what I said wasn't relate to the main point of your post. I just tried to point out the good thing of this process, which similar to Norton's "Full Computer Scan", that's it.

"It's a scanning process, it's going to scan through every bit of your data, that will take hours, and you can't undo it. Once it's finished, only new and updated files will be scan again."

I have my solution

The way I have dealt with these unstoppable or returning processes since avg 8 is to replace the offending file with a shortcut to a little app called Dummy Executable which does nothing and exits leaving the computer free of memory hoggers. Avgrsx.exe recieves same treatment.
Avg seems happy and still usable/updatable as a scanner.
I also have a shortcut which starts the avg service (previously disabled) when context scans or updates are required command line may be "X:\WINDOWS\system32\sc.exe start avg9wd" where X is system disk.
So I can have zero footprint with needed functions.
Thanks, Peter.

while i dont use AVG, this is just another good reason to make sure everyone i know continues to not use it.

Thanks for the heads up on this.

That was not a good example and for the most part confusing and misleading. What you said in your post was that you did a full scan of your hard drive. The optimization set in AVG 9.0 update is not implied as a full scan feature but an optimization feature that's appears similar to indexing. So that when you actually do a full scan it's much faster.

exacly, it will speed up the full scan. but it needs to know the current state of the files. its going to take longer to cache it then full scan vs just a full scan the first time this is run.

but now that its already cached, the full scan will be done much faster.



what makes you think an 8 hour low priority scan is excessive? its low priority.. meaning if your using your PC AT ALL in anyway it will overide the scan and slow it down.... so if windows or a program your running writes or reads anything at all.. it will slow it down. that is one reson it takes so long to run the scan.
(if your pc lags due to this, somthing else is wrong. maybe its a slow HDD)







(it has to do a "Full Scan" of your files to cache them so the Full scan that looks for virii will be faster.)
thats what he was saying. the cacheing process does a full scan of your files to cache them

avgchsvx is not working as described

Hi

My Compaq Presario V2000 laptop here, running XP Home, is maxed out most of the day, and as a result it gets very hot indeed. Usually, the major process causing this is AVG's avgchsvx.exe.

I read about what it is intended to do, and that it needs a good run to get set up, after which it's very light, picking up only the few file changes made since last time it ran.

Well, that's the theory, but it's not the reality. I left the laptop on all night a few days ago, and sure enough in the morning, avgchsvx was nice and quiescent.

Great, I thought, it's happy now.

But later that day, the heavy CPU usage started up again, and it's continued so ever since, on and off. Looking at it right now again, it's quiescent again, but it's had 3:41 of CPU time this morning, at a point where the System Idle Process has had less than 15:00.

And it doesn't even back off when I'm busy, when it's running. Burning 65% CPU on tasks I intended to get done, it takes the other 35%.

Some people have said well, it's CPU you're not using anyway. I say, I'd like the keyboard surround not to get uncomfortably hot.

I don't think AVG have got this right. This process should be much more background than it is. And why 100% CPU anyway? A full, real, AVG scan doesn't hammer the CPU like that, so why should a pre-scan?

And I can Pause a scan, if I need more resources for whatever else I'm doing. But I can't Pause avgchsvx.exe. I can't even 'End Process' it in Task Manager - or rather I can, but it's back in a few seconds.

I've seen fixes for this that involve renaming the offending file. If I have things aright, you just need to go to Tools/Advanced Settings/Cache Server and turn the nasty thing off.

In the scenario above, it might even have been enough to turn off just 'Enable Adding New Files into Cache'.

But I do hope AVG will revisit this option and rethink it; it spoils an otherwise good product that I don't really want to switch away from.

Finally, I note that the Help for Tools/Advanced Settings/Cache Server says
'We strongly recommend to keep this feature activated unless you have an explicit reason to switch it off.'

Well, I do have an explicit reason. It's MY computer, and I want it back.

AVG CPU Usage High

Installed AVG 9.0.851 a couple of weeks ago and found the computer was slow and freezing XP Home windows. Noticed the CPU Usage high running 70 - 80%, mostly due to Avgchsvx.exe, Avgwdsvc.exe and System Idle Process. Went into AVG Tools Advanced Settings and Disabled both Cache Server boxes. The CPU Usage went down to 4- 5% immediately. Just to see if it would go right back up to the High CPU Usage, enabled both boxes. The CPU Usage stayed low. Why?? Computer has been running for over 12 hours and still low CPU Usage. Hope it stays low so I have My Computer back!
