Lately my mom came bugging me, that her AVGFree 8.5 wont update anymore.
Therefore everytime she turns on her Notebook, she get a red cross by Windows
telling here that windows is not safe (because the Virusscanner is not uptodate)
and also a message by the AVG Virusscanner that the updates couldn't be downloaded.
(She's running WinXP SP3 on a Sony Vaio Notebook).
I told her just to wait a bit, because most probably the updateserver is currently
not available. (I have AVG8.5 too - but couldn't explain why mine is updating
and hers not)
Now 3 weeks later she's still bugging me that her AVG is not updating, so I sit a bit down
to have a closer look. I uninstalled AVG8.5, reboot, download the latest version, install it,
reboot again - but it still can't download the updates...
Next I wanted to ping the updateserver and went to START - RUN and wanted to
run CMD, but noticed that this makes the desktop go away for a few seconds
(no Console appearing, instead ALL Icons disappear from the desktop including the
Taskbar). I never saw that before and my first thought was that she seriously mucked
up something... Next I wanted to have a look in the Registry and tryed START - RUN: regedit,
but that also just makes the desktop icons disappear for a few seconds
(in both cases, the desktop icons and the taskbar appear after 5 seconds again,
but I can NOT start the console and can also not get into the registry editor).
Great... so I already prepared myself to backup her data and copy back an image
of the disk which I made a few months ago...
Just yesterday, somebody else came to me, telling me that he is having some "errormessages"
when he starts his XP... I went to that persons home, and noticed when he turns on his comp,
he also gets a red cross and windows telling him that the virusscanner is not uptodate.
He had AVG8.0 installed which also couldn't be updated anymore?
Ok, first try was again to uninstall AVG8.0, reboot, download the latest AVG8.5,
install, reboot -> and again same problem, AVG8.5 can't be updated?
(He's running WinXP SP3 on a Compaq PC)
Now I was sort of seriously thinking that it MUST be something with the AVG Update server...
Then I also tryed "START - RUN: CMD" on his computer - and look, SAME problem:
All Icons from the desktop and the taskbar disappear (you only see the light blue default backgroundcolor),
and after a few seconds the icons appear again (but no Console showing up).
Same with regedit (also can't be started).
My next try was to uninstall AVG8.5 and then I downloaded the Avira Antivir als alternative.
But look - also Antivir CAN NOT update itself??
I tryed to google around if other people have the same problem, but the only topic
i found was on http://www.bleepingcomputer.com/forums/t/206736/run-cmdexe-causes-explorer-to-crash/
I did not experience the problem with redirecting issues, but none of them
wrote something about having virusscanner updateproblems.
For me, it looks like this two problems have something in common.
For example some new Malware/Trojan disables the updating functionality
of the virusscanners (so they can remain unrecognized on the system),
also they disable somehow the access to CMD and Regedit.
Anyone else experiencing this kind of problems?
