I have been a long time user of AVG free version from 2003 onwards. The issue that i am facing at present is unique and has been observed in the latest version of AVG free editions. the problems have been systematically mentioned below.

1. System start up is very much delayed. Even after the windows start-up tune, task-bar & cursor pointer is not ready and takes additional 45-50sec to become active.
2. While listening to Media player,when other application (adobe acrobat/ MS word etc.) is started, the playing of the song gets stuck and sometimes even hangs the player.
3. Handling of 2-3 applications or multiple browser usage or folder access keeps the desktop stuck and Windows minimises in a slow motion.
4. starting certain system intensive application like "Blaze media", takes a hell longer time (almost 2 minutes)

AVGRSX.exe (Resident shield) consumes max CPU power (80-99%) each time an application is invoked and hinders/delays in the opening of these applications when started in all the above instances AS OBSERVED IN "PROCESS VIEW" OF TASK MANGER.

Prevent AVGRSX.exe from running while starting already installed application or prevent it from consuming max CPU usage.

Methods tried:
1. Adding path files for those applications in "manage exceptions" of Resident shield.

AVGRSX.exe runs the first time each application is started and delays the time taken for loading of application. subsequent run of those application after closing, does not activate RESIDENT SHIELD and loading is faster, AS MONITERED IN "PROCESS VIEW" OF TASK MANGER.

2. Disabling Resident shield and re-checking the performance upon restart.
- System activation after the start-up tune is just 14 sec.
- no hanging of media player or song getting stuck.
- easily handling more than 3 applications etc.
- System intensive application like "Blaze media" takes just 32 sec to start.

My System information:

OS: Microsoft WindowsXP- Professional
Version: 2002
Service Pack 2

RAM: 448 MB (512MB)

* Added through "Add List" option in Manage exception.
Others using "Add Path" option.

Is the inclusion of these file paths/lists correct?
What else should be done to improve the performance of my system?
These problems started showing only after i upgraded to the latest AVG version. (I have been using AVG from 2003 till date.)
What additional settings should be done to make AVG & its Resident shield perform efficiently?

Kindly provide your valuable feedback/advice/suggestion(s).
Thanking you in advance.
Warm regards.
Siva Adarsh.

You didn't list any other protection software nor did you say you had none and you didn't list if there had ever been any other antivirus installed ( previously or currently ) ... since these are the most common causes of slow performance.... please provide that information.

The following will also help most systems but may still rely on the above missing information...

First let's start by cleaning up all temporary files and check for registry issues. I prefer a util called CCleaner found at which does an even better job than the Windows Disk Cleanup and it also can check for registry issues. When checking for registry issues, run it about 3-4 times until it lists no other issues.

Check your hard drive for file/system errors by running chkdsk. Open My Computer and right click on Local Disk C: selecting Properties, click the Tools tab and in the Error Checking area click the "Check now" button and select both options. It will tell you that it can't test the drive right now and it will ask if you want to schedule it for the next system startup... select Yes. Restart your computer so that it can check the drive. This test will take some time to run and at times may appear stalled but just let it run.

Follow up all of that with a full Defrag to ensure the best performance you can of the system.

Thank you "rdsok" for highlighting the lacunae in my post. I will certainly provide the needful info.

Other protection software: Trojan Remover (trial version using database 7342)
Expires on: Today 06-Jul-09
Reason for installation: 1. Could'nt access AVG website (Even upon clicking on the link provided on the AVG 8.5 interface)
2. Windows Update site and not opening (showed website cannot be found), while all other sites opened/functioned properly.
The problem got solved after installing it and was able to update my WinXP SP2 and access AVG website.

Other antivirus installed: Nil (previous or current)

I will also try going through the suggestions provided. However, I am not sure if this would solve my problem.
The issue that i face is the CPU power consumption by avgrsx.exe (resident shield) as it scans each file when an already installed application is started.
since having given exceptions manually, the CPU consumption by avgrsx.exe is nil on the launch of application second time after closing but still consumes max power on first launch of the same application.
without giving exception, each time avgrsx.exe consumes max CPU power.
this maximum consumption of CPU for an already installed application is what i want to be eliminated or minimised. Can this be done?

mentioned avgrsx.exe CPU usage is mostly related with some other conflict application/infection.

Please be informed that in the next AVG9 will be implemented special algorithms to not check the same file without change twice (only after new virus database will be released), so it will solve many slowdown of computer.

Just for sure, please check last utility at this post - Gmer, if the output showed something interesting for us. As reported issue with no access AVG or Microsoft webpages definitely points to some infection and there could be some remaints.

I had - as many other people also - the problem of a very slow system start up with AVG8 free. This happend on both my desktop computer and on my laptop.
I my case I solved the problem by uninstalling the TrueCrypt encryption software and installing it again.
The AVG startup monopolised the system at Winlogon time, when the avgrsstx.dll is notified
