Hi Fellows,
Around few weeks, I feel kinda nervous about avast. It takes more than enough time to execute an application sometimes. I don’t know why this keeps happening around last few weeks and feels like its ONLY for ME. Once I had same problem with avast! IS 6.0.1203 and it was solved after applying a patch (http://forum.avast.com/index.php?topic=83543.msg680850) given by Asyn. But after upgrading to latest version, after few days same theory happens. Also lately I had experiences browsing degradation too. Now it’s been solved anyway. Strange is sometimes after re-installing or restoring settings it seems working better. But after some time, again I have to wait longer to launch applications.
Is this because avast! has better tracking of file sources as VLK imposed on new version or a driver problem?. Is there any patch for this? or solution to try out?
Thanks in Advance 
Cheers…

There’s some prob here too. Sometimes the prob is there & sometimes everything runs smooth.
Slowdown till the database is updated. Sometimes slowdown for few more mintutes after the database update. Slowdown opening a folder with many .exe files. Slowdown when browsing a page which has videos or images, photos, etc, the scrolling is not smooth. Sometimes browser with few tabs open hangs for a while & then returns normal & sometimes it takes more time to get back to normal. Sometimes things just stuck dont know why? So quite a few slowdown & sometimes everything is smooth.
Currently running CIS 5.8 Suite & no probs at all.
I think for most probs WebShield is the culprit. Youtube videos also buffers a lot when Avast installed. 4MBPS Connection here. No prob with CIS installed. So currently running CIS Suite.
Win XP SP3 Fully Updated
Either Avast Free with Windows FW or CIS Suite
No other security software.
Thanxx

No problems here either, XP Pro and win7.
Oh Guys, so did you have any problem with avast! version 6.0.1203? However I had this problem with that version and Asyn provided me the solution (a patch)…
I think, If you didn’t had that sort of a problem earlier, you guys on safe side…
Who can help me out as you think guys?
Cheers…

The patch that was previously for 6.0.1203 is/should be incorporated into the latest avast release, 6.0.1289.
So all I can suggest that you do a clean reinstall of avast IS:
-
Download the latest version of avast, 6.0.1289 http://files.avast.com/iavs5x/setup_ais.exe and save it to your HDD, somewhere you can find it again (if you didn’t save your last download). Use that when you reinstall.
-
Download the avast! Uninstall Utility, aswClear.exe find it here and save it to your HDD (it has uninstall tools for both 5.x and 6.0.x).
-
- Now uninstall avast! (using add remove programs, if you can’t do that start from the next step), reboot.- 2. run the avast! Uninstall Utility from safe mode, first for 5.x if previously installed and then for 6.0, once complete reboot into normal mode.- 3. install the latest version, reboot.
If that doesn’t resolve it, as the patch is incorporated into the latest release, there is something else in the mix.
Hi DavidR,
Thanks for your instructions…
Cheers…
Hi DavidR,
NOW I’m following your instructions. Already uninstalled. Downloading AIS now 
However after uninstallation (without AV), PC respond much faster than disabling real-time protection…
BTW does avast! has a conflict with Intel Application Accelerator or Internet Download Manager programs?
AND do you think using avast! FREE is better than AIS regarding to PERFORMANCE? (Just asking coz you’re using avast! FREE)
Cheers…

Well had you read my instructions, you should have downloaded all of the tools first, before uninstalling as that prevents you going on-line with no protection and your digital trousers around your ankles.
I have never used the Intel Application Accelerator, so I don’t know how it goes about its work, but there could well be extra processing effort required for that.
I honestly don’t see how it would give you that much, as your system is pretty restricted CPU and RAM, If you can get it at a reasonable price an extra 1GB, would see more of an improvement than the Intel Application Accelerator I believe. And it is removing that additional program running consuming resources.
Internet download managers shouldn’t be an issue.
I’m using the free version, and I don’t benefit from any performance improvements, I still have to have a firewall and anti-spam, etc. It is just that they are three separate programs, so the avast suite combining them may well be lower on resources.
Hi DavidR,
I have followed your instructions and did a clean reinstall… Last time I have updated over beta version. But this time I didn’t installed Mail shield, P2P shield with AIS. However I have uninstalled Intel Application Accelarator too. Now avast! working more smoother and I feel some improvement in performance too (when launching applications and browsing).
But let me have some time to evaluate the performance for next few days and see if it persists.
Really Appreciate Your Clean and Clear Instructions and Flexibility…
However (if you prefer) I would like if you can respond to my prior question about avast FREE… 
Cheers…
Oh thanks for your explanation mate
and yeah I think AIS better for me and love avast! Firewall. However you know it would better if I can add more RAMs, but currently I’m out of RAM slots… I started to use Intel Application Accelerator coz its designed for Pentium IV based Processors and when I have 256MB RAM.
Intel(R) Application Accelerator ~ Overview
The Intel(R) Application Accelerator is designed to improve performance of the storage sub-system and overall system performance. This software delivers improved performance through several ingredient technologies (components). Certain components will be available only on Pentium(R) 4 processor-based systems running Microsoft Windows 2000 and Windows XP.
However now its better to get rid of this and is nice to see avast running smoothly… And love the corporation of avast! community…
Have a Great Day… 
Cheers…

You’re welcome.
Personally I think it a mistake to disable/uninstall the Mail Shield even if don’t use an email program, but use web mail viewed through your browser. In fact I would suggest you leave it installed as it isn’t using resources unless it is actually running and I would go further to suggest that you set the sensitivity to High. The reasoning for this is, if you have a trojan spambot (they have their own SMTP program), which has got past your defences, either undetected or hidden; then your first indication could be the alerts from the Mail Shield of this activity.
I don’t have the P2P shield installed either, but I don’t use any P2P application, so if you don’t that isn’t a problem.
Thanks for Your Suggestions Mate
My avast! File Shield Sensitivity Level is Normal. And Now I’m having same problem after few hours. I rebooted my PC after the avast! definition update and now I’m experiencing the delay in launching applications and browsing.
Any further suggestions? May I try the FREE Antivirus on behalf?
Cheers…

Well you can start by checking out the task manager and find what is using the CPU cycles.
Do some housekeeping and only have applications running that are essential, open when required and close when not needed as your system is somewhat low on resources. Though there are others with lower system specs than yours and we aren’t seeing this.
In al honesty using the free isn’t going to see much change unless you don’t bother with a firewall and that is plain crazy.
Hi David,
I found something interesting… I think this would be a clue to find a solution… However I just disabled avast! Firewall NDIS Driver from my Local Area Connection properties. Now my PC working as the first time without having any performance issues.
Do you have any suggestions mate? Would it be something with avast! Firewall?
Thanks for sparing much time mate
You get nothing in return but I wish you to have all the success with you… 
Cheers…

Since I don’t use the avast Internet Security version, I can’t really comment on the firewall as I have no personal experience of it.
You don’t say what setting you have on the firewall, Home, Work, Public, etc. Having on a higher setting will increase its protection and consequently its resource use, in order low to high it is Home, Work, Public.
I have selected Home setting for my avast! Firewall mate. Didn’t touch any setting after reinstallation and never did for Firewall.
Cheers…

You’re welcome.
If having selected Home setting for the firewall I would have thought it wouldn’t be too concerned with your Local Area Network Connections, so I don’t believe that is the cause of any degradation. I believe in your comment “I just disabled avast! Firewall NDIS Driver from my Local Area Connection properties.” I don’t know if that just disabled the avast firewall.
So I would re-enable that and did into the task manager and see what is using the lions share of your CPU resources.
Hi DavidR,
Just switched to avast! FREE Antivirus (As My License Got Expired for AIS, Two Days Ago) and COMODO Firewall. Now my PC doing really great… I have no problem with performance and browsing yet. Hope this will be a good mix. Let’s see…
AND I checked my processes and CPU usage when I have AIS, but couldn’t find any critical processes or Peak usage of CPU…
Do you have any recommendations mate?
nice to hear from you…
Thanks AGAiN…
