Dear Avast,
Since Version 2011 I have been experiencing issues with uploading files to dmcloud and sproutvideo. The uploaders would claim that my upload speed was 3gb/s when the actual speed is kb/s I have found disabling the Web Shield fixes the issue however I wanted to find a simple fix. I installed the new beta hoping this had been fixed only to find that the issue is still active. I have installed a clean version of Windows and have gotten the same issues as before.
Problem:Uploading content to websites using flash and HTML5 uploaders results in the illusion of “ultra fast” speeds when the file is being actively skipped by Web Shield.
OS: Windows 7 64 Bit SP1
Clean Install?: Yes
Clean OS Install?: Yes
Avast Version: 9.0.9.2012
Troubleshooting: Disable Web Shield and attempt to upload file. File Uploads act normally. Reactivate Shield and uploads start to zoom up in gb/s rather than kb/s.
Installs: Installing from version 2011 to version 2012 caused the anti-spam module to disable it’s self. Installing BETA 2012 on clean OS Install has fixed this problem however the web shield issue is still active.
I have installed the latest BETA build and it has become even more unstable after doing a straight install over the previous version.
Should i do a clean install?
Thanks
Oliver
[update 1]: AVAST has offloaded some of the web shield resources onto the “cloud” causing a bottleneck when uploads happen. This was meant to improve performance and provide on-the-fly updates to the latest vulnerabilities however people with slower uploads/connections are finding this problematic. Testing was done on a fast network at AVAST so this bug wasn’t discovered until users started using the product. This has happened in the past with other Avast products and is just part and parcel of modern software development. It has been suggested that making the shield go into “proxy mode” ie without streaming updates should help provide a temp fix
[update 2]: I contacted Lukor to get an update on the progress of the bug, He provided me with an Alpha build which has fixed the issue. This should be passed down to everyone else thru a new software update however you will need to switch off of proxy mode to get the streaming mode back.
[update 3:Build 2013 has been released to everyone http://forum.avast.com/index.php?topic=145192.0;topicseen
