How Does Windows Ultimate Safeguard Infect Computers?

Windows Ultimate Safeguard virus infections can be aquired from the use and installation of freeware, shareware, and drive by download websites (such as Kangobox). Drive by download sites such as free streaming video websites usually ask and/or prompt the website visitor to install some sort of fake codec or flash player. In most cases with the Windows Ultimate Safeguard virus, the potential infected user is asked to install a fake version of Adobe Flash Player, which looks and seems real due to the rogue file being titled adobeflashplayer.exe or something similar.

If you visit a website (usually associated with free media, such as video) that asks or prompts for a codec, plugin, or file to be install in order to view or use their product, it is strongly suggested to avoid the website alltogether. Many viruses and other infections (especially adware and hijackers) are aquired through voluntary but unsuspected installation. Below is an example of an alert which is commonly placed at the top of a webpage in order to trick internet visitors into installaing malware.

Keep in mind, many websites, especially websites that host free streaming videos (free movies and TV shows) will have a similar alert bar. Some are not malicious, while most of them are. In actuality you don’t need third party codecs and plugins to watch streaming videos online if your configurations for realistic scripts like Flash and Java are correct. Flash, HTML, and other scripts which can be used to display streaming videos are far too evolved to require third party codecs and plugins. Some applications such as DIVX players and flash players use their own codecs and plugins which can be emulated by rogue malicious programs, which is exactly how the Windows Ultimate Safeguard infection infects computers.

Windows Ultimate Safeguard can also infect computers through other rootkits and may install alongside sophisticate forms of malware.
