Clicking these buttons may fetch executables (like .exe or .dmg files) that quietely install Trojans or Remote Access Trojans (RATs) , giving intruders control over your device.
Genuine download buttons are rarely labeled as ads. Look for a small "X" or the word "Ad" near the button; if present, it is not your file.
If you see this button on a site that is not an official software distributor, it may be a "fake download button" designed to trick you into clicking an ad or downloading unwanted software.
