The use of pirated software or unauthorized license keys may violate ESET's Terms of Service and local copyright laws. It is always recommended to support software developers by purchasing legitimate licenses.

If a site asks you to download a .exe file to "activate" ESET, be extremely cautious. A genuine license key should be entered directly into the official ESET software.

ESET offers free 30-day trials directly on their website, which are guaranteed to be safe and functional. [10]
