Hi,
my computer has been (or is) infected by Vundo and I did a lot of cleaning action following your instructions. Thanks for/to this Forum
I've done the 8 steps several times, removed a lot of infects during the last weeks and today there isn't anything reported anymore as threat
However
IE8 (and before also IE7) and also the newest version of Firefox is not able to get into the Internet. Message: Firewall is blocking the access.
The older version of Firefox is running
Update of Antivir or Java is also not running due to missing accessibility to Internet.
I checked in ZONE Alarm and allowed the access manually without succes.
Is there another setting (form which firewall ever), which is blocking??
Thanks for some tips

Problem solved

Hi everone who is interested in getting some info about root cause.
Firstly - problem solved and I'm really happy.
Some months ago I've got a trial version of Norton Security, which I deinstalled after 50 days (I think). Deinstallation has been done with related software out of this program.
Now I read somewhere in this forum, that there is a software called: Norton Remover and I assumed that there might be a reason for the existence of this software.
I searched in the internet, got it, ran it and
I've got the message from Norton via IE, that I could now purchase it.
For sure I was happy, that IE now was working. However, I'm upset with this way of working of some provider of security systems.
Thanks to this techspot platform again. Finally the tip to solve the problem was written down here.

Thanks for the update :grinthumb
