Yes, I mean removing those drivers (if you have a wireless connection).
As for the drivers...they (and all other system drivers) should be available at the website of the system manufacturer.

<<...and I can not uninstall that WLAN Adapter.>>
You should be able to go to Device Manager and simply right-click on the item and click the uninstall option. Is there an error message when you do that?
I guess that I'm somewhat troubled by your statement in your initial post...that you suspect a virus. None of this will overcome that particular trouble.
