Web shield and Mail shield doesn't work after restart

Hello,
Yesterday I install Avast! 5, allways after a restart the Web Shield and Mail Shield doesn’t work.
I try to click on “Fix Now”, on the “start” button in the shields’ panels but only after long time those shields are start to work.
I try uninstall a lot of time, I used the regular uninstallation and the Avast! remover, and then re-install, but still this is doesn’t work.
I checked the Services and saw that “Avast! Web Shield” and “Avast! Mail Shield” are start manual and not automatic, I try to change it to “automatic” but “Access is denied”.
In my brother’s Computer those shields work exellent and there i wasn’t touch anything.
So I don’t know what to do, I tried everything, please help me.
NB
My system is Windows XP SP3. (In my brother’s computer too.)

Good Weekend and Shabbat Shalom.

They only need to be manual start as they are user selected options, you the user select if the Web Shield or Mail Shield should run. If set to auto that wouldn’t be yourchoice.

The self-defence module may well be blocking this in any case.

How long does it take them to start ?
I have XP Pro SP3 and generally they start immediately, though I have had it happen where they took a few seconds.

Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?

What other security based software do you have installed ?

Okay, I disabled the Avast! self-defence, then quickly turn those shields into a automatic service and re-enable the Avast! self-defence.
After this I restart the computer and the Web Shield started immediately but still the Mail Shield started only after more than ten-twenty mintues.
I don’t use Outlook or other E-Mail program, so this shield is not so important to me, but still i want to fix it.
How do I do that?

Start by answering the questions asked in my last post as remnants of previous AVs and other security applications can have an impact.

I don’t have any other anti-virous, I had trial of Mcafee and Free AVG and I uninstall them.

There may be remnants, so try these tools:

Or http://majorgeeks.com/McAfee_Consumer_Product_Removal_Tool_d5420.html

2007 version - http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

  • Ensure that all remnants of AVG are gone - AVG8.x (or higher) Remover, download tool from here, http://www.avg.com/download-tools there is a 32bit and 64 bit windows version, ensure you use the correct one.

Still, the Mail Shield is don’t working.

So you have run both of those removal tools and no change.

It may be best to do a clean reinstall of avast:

  • Download the latest version of avast, 5.0.545 http://www.avast.com/free-antivirus-download and save it to your HDD, somewhere you can find it again (if you didn’t save your last download). Use that when you reinstall.

  • Download the avast! Uninstall Utility, aswClear5.exe find it here and save it to your HDD (it has uninstall tools for both 4.8 and 5.0).

    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 from safe mode, first for 4.8 if previously installed and then for 5.0, once complete reboot into normal mode.- 3. install the latest version, reboot.

I started having the same problem as well today, these two shields start disabled after reboot and need to be enabled manually.

System is Vista SP1 (or whatever the latest SP is anyway)

The only other security program is Comodo firewall (edit: Avast is firewallless version). Nothing else was ever installed on this PC.
Curiously enough, in all of the last reboots when avast services were disabled on boot, Comodo did not launch automatically either and I had to launch it manually. I had this problem with Comodo occur a few times in the past, but never several times in a row,

Please somebody help?

Have you not followed the suggestion in my previous post to do a clean reinstall ?

I have did all, the shields are still doesn’t work.

Well the firewall shouldn’t stop the shields starting (as far as I’m aware). However the Comodo firewall doesn’t come as a stand alone firewall application any more but as a part of the Comodo Internet Security (CIS) suite, which comes with an antivirus element. So exactly what have you got installed from comodo ?

Firewall and defense module, but not antivirus. I also had them both running for ages, until this problem appeared one day. (no changes were done to the system, and the new only program that was installed recently was Nokia Ovi Suite for connecting the mobile phone).

Edit: also not sure if it’s relevant, but a couple weeks ago my Bios settings were reset (probably because of a power spike). They were fixed, but the PC had a date set to several months in the future for a day or two. Can this interfere with finding the most recent version of something?
