It's not a virus just malware with unexpected or unwated behaviour that can run on Wine like every other Windows software, therefore:

• Do NOT execute software from untrusted sources (applies to all software and software packages; is not limited to Windows software; also includes tarballs, debs/rpms and shell scripts).


• Think before executing Windows software, even if you trust the source.


• To get rid of the nagging behaviour:
  
  
  
  • Remove Wine entirely or...
  
  
  • Remove the ~/.wine folder, which is equal to reinstalling Windows.
  
  
  • Backup your home folder and start with a clean one (or just create anoher user).
