Serious problem with script blocking

Completely removed NAV with the tool suggested.
I continue having problem with scripting as supposed.
Do exists a tool to completely remove Avast?

Please, someone can tell me how script blocking of Avast works?
Even in private mail (d.cicognani [AT] ciconet.it).

Food for thought. I don’t know if this has any bearing, but I was told once these script errors can be caused by web pages that are running a different version of Java than the user. I uninstalled the old version of Java and then downloaded the latest version. Then I went to Internet Options, Programs, Manage Add-Ons, selected the java items and clicked the Update ActiveX button. They may be old/corrupted. Now I don’t get nearly as many of these script errors as I used to, and when I do, I just click the No button. Maybe the OP just needs to update Java and the activeX for it? Worth a try.

Edit: Sorry the duplicate post occurred while I was editing the first.

It’s not my case, but I tried to update Java.
It doesn’t work.

I’ll say another time: THE PROBLEM IS AVAST!
The script blocking provider has a bug that completely block any kind of script (JavaScript, vbScript, ActiveX, Java) in Internet Explorer and in any other Windows program that uses IE controls (like many parts of the control panel, Microsoft Outlook and so on). This provider also block Firefox, but stoping the provider means Firefox start working againt. IE, instead, still doesn’t work.
Before installing Avast! the problem there isn’t, after installing Avast! the problem started and there was no way to stop this bug.
Even uninstalling Avast! the problem is still there.
I want to know WHAT SCRIPT BLOCKING DOES when first installed, because I have this problem since one week and I have to solve this problem.

I’m a web developer and search engine expert: I can’t work without IE properly working!
Sorry but if noone can help me I must format my PC: if this happens, it means that I will make a very bad advertise of Avast! on every forum and newsgroup.

piciuriello, avast! has nothing to do with Java - it’s another proof that the problem is somewhere else.

On installation, avast! registers itself for common JavaScript and VBScript classes (and of course, stores the original value - for passing the requests to the real engines, and also to restore the original values during deinstallation). I think these engines are only used by IE and related components - i.e. I doubt it could affect Firefox in any way.
The relevant keys (changed) are under HKCR\CLSID
{B54F3741-5B07-11CF-A4B0-00AA004A55E8}
{B54F3743-5B07-11CF-A4B0-00AA004A55E8}
{F414C260-6AC0-11CF-B6D1-00AA00BBBB58}
{F414C262-6AC0-11CF-B6D1-00AA00BBBB58}

There are also some memory-hooking techniques employed, but I repeat:
If the mentioned registry keys point (with their InprocServer32 subkey) to the respective engines (vbscript.dll, jscript.dll), and avast! is uninstalled (i.e. not running), it cannot affect your scripting in any way.

Very good!
You finally told me what Avast! does on install and I fixed the problem.
The registry keys:
{F414C260-6AC0-11CF-B6D1-00AA00BBBB58}
{F414C262-6AC0-11CF-B6D1-00AA00BBBB58}
were completely absent, but there was only a key:
{F414C261-6AC0-11CF-B6D1-00AA00BBBB58}
as I told in a previous post.
I reconstructed these keys from a backup I, luckly, had, and now all is working again.
Maybe I was only unlucky, but I strongly suggest a registry backup just before installing Avast! to everyone.
Bye bye and thank’s.

avast! certainly doesn’t delete these keys, it manipulates only with the underlying values - so the keys were not present on your computer before installation (in which case, avast! wouldn’t change anything there), or got deleted afterwards.
Reconstruction is probably not necessary, registering jscript.dll or vbscript.dll using regsvr32 should create all the necessary keys.

How exactly did you uninstall avast!, btw?

I don’t know why, but before installing Avast! IE worked, then it doesn’t work.
So the only explaination is that Avast! was the problem.
However, I uninstalled Avast! using the uninstall tool that was installed with Avast!

I checked the source code - there are only very few references to this registry key name, and none of them deletes any key. So, I can say for sure that avast! didn’t remove those keys.

Sorry to interfere again, but i have teh same problem that had piciurello, i will try to recreate the registry keys mentioned by him
