WinXP Home/SP3, fully updated
AVG 2012 Free, fully updated, with only antivirus and rootkit components installed.
Task Manager shows AVG (avgrsx.exe and avgcsrvx.exe) is always very active (several hundred additional PFs every 5 seconds; frequently there are totals of millions of Page Faults) even when nothing else is running (except the OS). This continues when the antivirus component is deactivated.

No malware is found by AVG (or several other on-demand scanners)

What is AVG doing, particularly when the AV component is inactive??

Hello xxyyz,

This issue might be connected to the AVG Cache Server Service. What is the status of this issue when the AVG Cache Server is disabled?

We would like to request more information (Screenshot, MSInfo output, System Event Logs and all AVG log files) regarding this issue.

Thank you.

Thank you for your reply.

Most of the activity continues whether caching is enabled or disabled.

PF Deltas (from Task Manager) - always a 5 second cycle, the specific
numbers vary a little, but these are representative.
Antivirus Eabled Disabled Enabled Disabled
Caching Enabled Enabled Disabled Disabled
avgcsrvx 0/0/ 0/ 59/0 0/0/ 0/ 59/0 0/0/ 0/ 59/0 0/0/ 0/ 60/0
avgrsx 0/0/48/120/8 0/0/48/118/8 0/0/ 0/ 95/8 0/0/ 0/ 94/8
As you can see, disabling the AV component does virtually nothing;
disabling caching drops the avgrsx PF deltas by about 40%, but has no
effect on the avgcsrvx PF deltas.

I have Attached a zipped folder (AVG.zip) including:
1. taskmgr.jpg - a screen shot of the Task Manager (with caching and
the antivirus component enabled, and with no AVG scans taken since
boot). I assume this is the screen shot you wanted?
2. app.evt, sec.evt and sys .evt (the Application, Security and
System Event Logs)
3. msinfo.nfo - the msinfo32 log.
4. All the AVG log files (in
D1401F9A-2407-4886-A984-ED4C5F6DED33[e8b8b002-7610-47d1-b6fb-d15a92122194].cab

Hello xxyyz,

Please let us inform you that your computer has only 256MB of the RAM memory. The minimal amount of the available RAM for AVG 2012 is 512MB. More information about AVG 2012 requirements can be found here. Note that the Page Faults are connected to the size of the memory. We recommend upgrading your RAM memory to decrease Page Faults.

Thank you for your understanding.

Thank you again for your feedback.

I am aware that the computer only has 256MB of RAM and that the
minimum requirement for AVG is 512MB. I must say, however, that AVG
has run with no apparent problems for the past 6 months.

I am also aware that, if a Process is active, there may be more PFs
with low RAM than with a larger amount. But that is ONLY if the
Process is doing something. The observed behaviour (1 000 000 PFs
every 4 or 5 hours for each of avgrsx.exe and avgcsrvx.exe, with the
antivirus component deactivated and caching turned off) implies AVG is
continuously doing something.

So I return to my original question - what is AVG doing?

Similar issues with 2Gb or RAM..

I am having similar issues to those described. I have 2Gb of RAM on a Windows XP machine.

avgrsx.exe is the single largest contributor to the number of page faults of any program on the system.
This happens even when the system is completely idle and Resident Shield has been disabled (which is what I originally suspected was causing the problem).

This doesn't seem to make sense and continuous page faults will clearly impact the performance of the system...

High CPU usage..

I have similar problem not sure if PF are involved BUT hard disk active for 4 or 5 hours once or twice a week. Makes my computer useless. Windows Task Manager shows HIGH cpu usage and Hard drive active continuously. I have 512M RAM. I DO NOT have any scheduled scan running. CPU usage will jump between 11 and 60 sometimes high will be 80. My AVG Version is 2012.0.2195 Virus 2437/5121 LinkScanner 1130.

Edit.. additional info.. High CPU usage is for avgrsx.exe

Help..

Can anybody tell me why our "TechBuddy" stopped responding ?

Thanks for your reply/information

Thanks..

My post was July 9 that puts it in the "Workdays" window and I did not feel the "other forum members" answered the question to resolve the problem.

Again thanks for your response
