Post-update problem on WinXP
« on: December 05, 2012, 10:26:59 PM »
A significant group of Russian users complaint that they lost internet connection and even damaged their WinXP systems after 121205-0 update: http://forum.avast.com/index.php?topic=110770

Avast signaled they have some viruses and they deleted the suspicious files. After that they lost all settings for internet connection.

I advise them to send messages to Avast support but I can't help them with anything more substantial. I think Avast experts should pay attention to the thread.

They "aren't sure". One of them deleted svhost.exe and "some other files". By the way half of the posters in the thread work in support departments of internet providers. I think they work in the same company.

And could you ask them directly in the thread? Write them in English and I'll try to translate.

And what should they do now? They tried to re-install Avast but as soon as they get 121205-1 update everything crashes again.

There is the option to delete or ignore ..  Select ignore (no action)

Edit : Although having said that I did a full scan  on my XP vm and nothing was detected

Hi there. Any suggestions to assist users who actually deleted the file?

It was an FP on TCPIP.sys it will be corrected on the next stream update
And what should they do now? They tried to re-install Avast but as soon as they get 121205-1 update everything crashes again.
As my XP vm say 121205-1 is fine.

I have just advised the users to restore their systems and to re-install Avast. To tell the truth it was a real avalanche of complaints in the middle of the night. Sorry but I have to go to bed because it's half past one here and I must get up at half past five.

I have the same problem on different PC in different companies, with windows xp installed. I think the reason of this situation is patched tspip.sys. By default tcpip.sys have 10 connections and with help of some utils, people patch it for exampel 100 connections, this actions i did by my self on all the computers where this problem is. One of this patcher calls Half-open_limit_fix_4.2.exe

Lots of not original windows xp distributives have alreadypatched tcpip.sys.
When I unninstall avast and recover tcpip.sys from file c:\windows\system32\tcpip.copy network doesnt work. I steel try to find a solution, because i dont have a distrubutive of windows now with me to recover from it, i think this comands could be solve a problem
expand X:\i386\tcpip.sy_ c:\windows\system32\tcpip.sys
You make me work hard today to fix this problem, it is easy to kill my self :) , becase I have 150 PC clients, and big mount of them already kill tcpip with avast..
p.s. your captcha make me mad, its very hard to see symbols

I can confirm this problem occurs with Windows XP systems which have a patched tcpip.sys.Multiple systems on multiple locations affected

User Obramko created a fix that can repair the damage:

Quote
Download the fix from here: http://depositfiles.com/files/jx9xqxtes

Unpack the archive, run the file fixtcpip.bat and restart your computer.

And some experienced users suggest two improvements for Avast:

1) To set Avast by default not to delete suspicious files but to move them to the chest;

2) Even if users choose to delete a file, a copy of it must be automatically sent to the chest.
