I'm using Avast Free 5.0.677 (currently, the most updated stable version) under Vista Home Basic. The problem:
When I open Avast's UI, clicking the "Scan Computer" section, Avast takes about a minute to respond. In the meantime, under Windows Task Manager, Avast gets to a status of "not responding", instead of "running". If I wait long enough, Avast's UI returns to a normal "running" state. Checks already done and reproducible behavior:
This happens every time I click at the "Scan Computer" section in Avast's UI. This description is not related to boot times, since the behavior happens a long time after the booting process finished, and can be reproduced every time, even hours after booting and working with the system.
I want to be clear about the previous paragraph. The delayed behavior could
potentially be related to booting delays, but the behavior I am describing is happening after
the booting process finished.
So please, if anyone answers to this topic about "booting delays", I would appreciate if the post would be related somehow to the behavior I described here. The issues could be potentially related, but "booting delays" is not the central issue of this topic. Avast's UI delays is the main issue here.
For example, let's say I am already there at the "Scan Computer" section and the UI is already responsive. If I click on any other Avast's UI section, that section is displayed immediately. But after that, if I click again on the "Scan Computer" section, the previously-described behavior appears again ("not responding"; takes about a minute to respond).
I noticed a similar behavior while I was using previous 5.0.xxx versions. I just didn't report it, in hope this behavior would disappear after updating to some new release. Yesterday I updated to 5.0.677, and I saw the same behavior, so here I am reporting it.
As with almost every software report, there is always a chance the problem has nothing to do with Avast, but it is related to something else.
I've already searched the forum, and similar
behaviors are being seen by other users: http://forum.avast.com/index.php?topic=61817.msg524148#msg524148
and the post just following that one at the same topic, which is linked as: http://forum.avast.com/index.php?topic=61817.msg524339#msg524339
are somehow relevant to the issue described in this topic.
I also read this topic: http://forum.avast.com/index.php?topic=61179.0
The problems seem to be similar to mine in some ways, but either they are more related to booting delays instead of Avast's UI delays, or they are focused on other/different sections of the Avast UI.
Now, the topic at: http://forum.avast.com/index.php?topic=61232.0
was very similar to my issue, but in that case, an update to the latest (at that moment) Avast version solved the problem. In my case, it doesn't.
So, having those topics in mind, I want to add some info. Additional information:
1- In my system, the section with delayed behavior is the "Scan Computer" section, not the ones that were referred to at previous posted topics.
2- I'm not talking here about Windows starting/booting delays, but about Avast's UI
delays (which may or may not be connected issues).
3- It seems like the OS's version (Vista/XP/...) is not
a common ground. There may/might be some common factor/configuration related to the OS, but if that's the case, it seems to be a common factor across several Windows' versions.
4- I do use Ccleaner daily, but the "System" and "Advance" sections of Ccleaner are disabled in my system, so it seems that the delay has no relation to Windows prefetch being cleaned by Ccleaner.
5- I experiment with Windows prefetch being on and off. I discovered no difference in relation to Avast's UI delayed behavior in my system. It is possible that more thorough tests are needed to get to a valid conclusion in this matter.
6- I use additional software, besides Avast, related to PC security. SpywareBlaster (which doesn't need to be running permanently, but its settings are a "permanent" state configuration until they are changed again); and Windows Defender, which comes included in Windows Vista. I also use the default Windows Vista firewall. No additional firewall is/was used.
7- The only security-related software previously installed was Avast Home 4.8. I uninstalled it when I upgraded to Avast Free 5.0. I did not
use the Avast Clean Tool to uninstalled Avast 4.8 at that time. No other antivirus was/is installed.
8- I have no hardware firewall. No router or similar device. I use a cable-modem to connect to the Internet.
9- I am the Administrator of my PC. I usually use other user name (not the Administrator user account itself), but I do have administrator permissions.
10- The only web browser I have installed is Microsoft's Internet Explorer (version 7, not 8 ). Possible related issues, relevant info and/or indication of solutions?:
-As I said, the boot delay could be related, or maybe not.
-The virus database occupies several MBytes and is updated frequently. Even defragmenting the HDD every day could still leave Avast's related files fragmented after a virus database update, and maybe this fragmentation causes UI delays. It still sounds strange that this delay happens when opening the "Scan Computer" section, but not the other sections of Avast's UI.
-My video controller is embedded into the motherboard itself. The video memory is controlled by the driver and the BIOS. Both, video drivers and BIOS are the most updated ones.
-The video memory in the BIOS is set as sheared with the main RAM (as opposed to being set as a reserved fixed size). I haven't seen any difference while testing this settings.
-Although part of Avast's UI is showing some problem, I have not seen the same kind of delays in any other program/software in my system, so I'm not convinced that a change in video-related settings (BIOS and/or driver) in my system would have any impact. I may be wrong, though.
I am experiencing an additional Avast's UI delay, which happens when scanning a file using the right-click function while selecting a file in Windows Explorer. I say this as an additional info for the developers, since the delays could potentially be related. But I don't want to mix the issues in the same topic. The central issue of this topic is still the "Scan Computer" section of Avast's UI not being responsive (enough).
I'd like to know if this behavior was already reported, or is an already known behavior. Does anyone else saw this delayed response behavior?
