I got a virus infection, as i persume.
First, my Kerio Personal Firewall and my Antivir Personal Edition, both never updated, were closed by the malware. Later, icons, like "Anti-Spyware" or icons of adult content appeared on my desktop, after a message box told me, the new windows update or something like that was installed.
Then I went online to get the latest signatures for my anti-virussoftware, but the startpage also seemed to be hijacked.
I rebooted and 3 white crosses in red circles appeared in my status bar. If i go over them with my mouse, it is said in a tooltip, that my computer is infected ("this computer is infected")
Also there are unknown files in my taskmanager, like vxh8jkdg7.
What do I have to do?
