Unfortunately I don't know what to say other than what I did earlier what was found in the scans I wouldn't have though would have been the cause so were back to this intermittent on off problem.

Whilst it isn't ideal the only alternative would be to terminate the web shield. If doing this personally I would stop using IE and only use firefox with the NoScript add-on installed.

You say you have reinstalled before, but I don't know if you have done a clean reinstall, so give this a shot.
Download the latest version of avast http://www.avast.com/eng/download-avast-home.html and save it to your HDD, somewhere you can find it again. Use that when you reinstall.

Download the avast! Uninstall Utility, find it here and save it to your HDD (if you didn't already do that).
  • 1. Now uninstall (using add remove programs, if you can't do that start from the next step), reboot.
  • 2. run the avast! Uninstall Utility, reboot.  If step 1 failed it may be necessary to run this from safe mode, once complete reboot into normal mode.
  • 3. install the latest version, reboot.

The HJT may show some possible connection issues.

Other than that I have no idea what else to suggest.

David, you have been tremendous in your efforts to assist - thank you. I've uninstalled and reinstalled several times now, as you suggest (although only once used the avast! uninstall utility), but after seeing what sort of responses come back re the HJT report, I'll try again if necessary.

tarq57 - not rude at all! I am extremely grateful for any suggestions that might lead to a resolution of this situation, which is now REALLY getting under my skin.

So thanks! I've done as you suggest and have the HJT report, but can't post it here as the message exceeds the maximum allowed length of 10000 characters! Can I attach it, or something?

When you click the Reply button, there is an Additional Options link, this expands the options to attach a file, that can be an image file or a text file (.log or .txt).

Fix:
O3 - Toolbar: (no name) - {3041d03e-fd4b-44e0-b742-2d9b88305f98} - (no file)
This is the Ask toolbar considered adware by some, but it doesn't appear to be active so the entry should be removed.

Is this your ISP ?
Amnet IT Services Pty as that is what the IP address indicates in the O17 - HKLM\System\CCS\Services\Tcpip entry is.

Other than those I don't see anything obvious, certainly not anything that might be related to this problem.

Hi again, David.

How do I remove the O3 - Toolbar, please? I'm not sure what it is or where it is!

Amnet IT Services Pty is my ISP, yes.

Bloody hell, it seems this problem is weird in extremis. It ain't no virus, it ain't spyware, it ain't anything picked up by HJT - WTF is it? Sigh...

Thanks so much for your ongoing assistance, anyway, David.

Run HJT again (close any other windows except HJT), tick the box to the left of the suspect entry you wish to fix, click the Fix Selected Button.

I have been messing around with the Avast settings trying to isolate whatever might be causing the problem with my browsers, and find that stopping Webshield returns the browsers to normal function. UNtil now, I thought turning off On-Access Protection Control was the only way to get the browsers browsing normally.

I subsequently noticed on the Avast FAQ page, there is the following question and answer:

Q: I have installed avast! and I can no longer browse the Web. How can I solve this?

A: Check your firewall configuration. For the correct operation the Web Shield process (ashWebSv.exe or aswWebSv.exe) needs a permission to access the Internet (TCP port 80) and a permission to act as a server and accept incoming connections from localhost (the local machine) on TCP port 12080.


I have the Windows XP (Home, SP2) Firewall. Can anyone give me simple instructions for granting the Web Shield process "a permission to access the Internet (TCP port 80) and a permission to act as a server and accept incoming connections from localhost (the local machine) on TCP port 12080" please? Maybe not having done this is the problem??

The XP firewall has zero outbound protection so there is no need to apply anything to it.

The FAQ instruction related to firewall that monitor outbound traffic.

OK, ta David.

Latest update - browsers behaving normally today with On-Access Protection on! Dunno why, don't care. Hopefully whatever the problem was has somehow resolved itself. Fingers firmly crossed...

You're welcome, my fingers are crossed too, I hate mysteries though, intermittent ones even more so.
