3721 claims
3721 Internet Assistant includes many useful features, such as IE setting repair, security shield, removal of internet history information and blocking ads. However, it installs various windows hooks that will slow down the system, and tries to install the hooks repeatedly. Some users also reported that Internet Assistant buttons reappeared immediately after their manual removal using Internet Explorer customization features, and
Blue Screen of Death appeared when using Internet Assistant.
Internet Explorer extension hijacking 3721 Internet Assistant will enable/disable other Internet Explorer extensions, except the advertisement links and extensions installed by Yahoo products.
Concealment and resistance to user termination 3721 Internet Assistant runs under multiple
rundll32.exe processes. If one of them is killed in
Windows Task Manager, it will immediately be restarted by others, thereby resisting efforts by a user to terminate the application. A
driver named
CnsMinKP.sys is installed with
3721 Internet Assistant, along with several hidden
Windows services. After uninstallation, several files are left on the system, but they are not visible in
Windows Explorer. They can be found by using tools such as
Total Commander or in the DOS box.
Removal of antispyware program Yahoo Assistant also removes 360Safe, an
antispyware program of a competitor, without notifying the user. On August 15, 2007, a Beijing court ruled this behavior as
unfair competition. ==Uninstall==
