FlashGet (formerly JetCar, from the literal translation of the Chinese name 快车; Kuàichē) was a freeware download manager for Microsoft Windows.

It was originally available in either paid or ad-supported versions, the latter of which included an Internet Explorer Browser Helper Object (BHO).

It supports HTTP, FTP, Microsoft Media Services, RTSP, BitTorrent and since version 1.8.4 eDonkey[2] downloads.

FlashGet has suffered from security flaws in its update mechanism which caused users to become infected with trojan viruses.

A malicious FGUpdate3.ini modified for exploit and introduced directly through the developer's server could cause FlashGet to download malware to the computer without alerting the user.
