[MiKTeX] TeXworks behaves like a virus

[Hartmut G. <gra...@lf...>]

Dear friends,

Since the newest update of MiKTeX 2.8 the editor TeXworks is 
automatically installed. Problem: At least all files with the extension 
.tex are now associated with TeXworks. But the main problem is: I cannot 
change this (not by right-click on the file etc., not at all!). This is 
a behavior like a virus. Since I use WinEdt as my favorite editor I have 
now a problem.

Does anybody know how I can change this association or (much better) how 
I can remove TeXworks from my system?

Hoping for your help,
Hartmut
