i did all what you described.
Thanks i learned a great deal regarding safety during the complete process of virus removal.
One thing that did not work out was to uninstall ComboFix:
* Click START then RUN
* Now type Combofix /u in the runbox and click OK
When i did that Combofix just ran again but is still installed on my system.
Any advice?
Is it a security thread or can i just leave it installed?
Further Spybot also seems to deal with the Host issue.It is writing something into the host.txt file. Is it still necessary to run MVPS Hosts?
Thanks Chris
