The program may modify the following registry entries:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\: "IEXPLORE.EXE"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\: "efast.exe"


The program is a web browser that uses code from the open-source web browser project Chromium.


The program sets itself as the default program to display files with the following extensions:
  • .gif
  • .htm
  • .html
  • .jpeg
  • .jpg
  • .pdf
  • .png
  • .shtml
  • .xht
  • .xhtml
  • .webp

The program also associates itself with the following protocols:
  • FTP
  • HTTP
  • HTTPS
  • IRC
  • mailto
  • MMS
  • NNTP
  • SMS
  • SMSto
  • Tel
  • URN
