I’m also having this problem on my 64bit Vista PC. Avast is practically dead - only the web shield seems to be active :-[.

Vlk, I cannot find the alwil software folder inside Program Files ???, although there is one under ProgramData.

It depends where you installed the program to.

C:\Program Files\ALWIL Software\Avast5

is the default location, unless you changed it in the setup wizard.

@Silent Assassin post:19

Also, do you need all of the drivers in C:\Windows\System32\drivers?

No, sorry, I edited my post, we only need asw*.sys files (all of our drivers are named like this).

Thanks

Silly me - I could have thought of that
I’ve already sent you 3 files (I hope you’ve got them):
[ProgramData]Avast5 (Silent Assassin).zip
avast (Silent Assassin).reg
drivers (Silent Assassin).zip

I’m also sending you avast! Free Antivirus (Silent Assassin).zip which is the folder to which I installed avast.

Thanks

Thanks. One little thing: the registry export is from HKCU, not from HKLM. Could you please also do one from HKLM?

Thanks

You mean HKEY_LOCAL_MACHINE\SOFTWARE\ALWIL Software? I don’t have such an entry there ??? (see screenshot).

[Vlk]

Oh you have 64-bit Windows, right?
Then it’s HKLM\Software\WOW6432Node\ALWIL Software.

Thanks

OK, I’ve sent it. Look for avast (Silent Assassin) [new].reg

[Vlk]

Thanks much. It looks like the driver files haven’t updated (are still version 677).
Please try doing the following: copy the *.sys from

D:\PROGRAMY\avast! Free Antivirus\Setup\INF\x64

to

C:\Windows\System32\Drivers

(actually, you don’t have to copy aswFW.sys, aswNdis.sys and aswNdis2.sys as these belong to the AIS firewall - but even if you do copy them, it will do no harm…).

After copying the files, reboot the computer. Does that solve the problem?

When copying I get a message saying that I don’t have the permission to do that (LOL - I’m the administrator ???).

I’ve disabled avast’s self-defense module and it worked. I will reboot the computer now.

[system]

Hooray! Avast is working now :D!

However, there’s still one thing - the behaviour shield isn’t showing any activity ???. What’s wrong?

[Vlk]

There’s one registry value missing. Namely, in

HKLM\System\CurrentControlSet\Services\aswSP\Parameters,

create a REG_DWORD value called BehavShield and set it to 1.

Then reboot and see what happens.

Yeap - it’s working :D.
Thanks Vlk!

When this (the behaviour shield issue) will be fixed? I don’t want to edit the registry, because I hate doing that. Because of that issue I haven’t updated to 5.1.864 and I’m still sticking with 5.0.677.

Probably tomorrow evening.

BTW if install from scratch (i.e. uninstall 5.0.677 and install 5.1.864) you shoudln’t be impacted by any of the issues.

same thing here :-X

Ok. Do I need to only run the Avast removal tool to have a clean installation or do I have to delete manually Avast files or registry entries?

[system]

I have updated 3 machines, 1x32bit and 2x64bit Win7 , I have seen only one issue and that is IE9 64bit will not run virtualised everything else is fine so far.

Hello. My shields except for web aren’t scanning either. So do I need to uninstall Avast! and reinstall?

I think this is related to your other issue in the topic you created, so follow the suggestions given there. http://forum.avast.com/index.php?topic=68623.0

[system]

will this be fixed via VPS update or a new build?
