What is DSI?

DSI is a geeky Trojan infection. It injects malicious code into Windows system folders to cause malfunction. Actually, it is generated by cyber criminals to exploit vulnerabilities on your computer and steal confidential information. DSI is capable to dodge from protection tools by dropping its files into legit program file folders. So you may experience program failure constantly and receive error messages. After it penetrates inside, it adds its own entries to the system start-up foulder to ensure its automatic activation. Moreover, the PC will be seen to slow down, freeze and even break down from time to time. Network connection turns unstable and Internet speed decelerates tremendously.

DSI is normally bundled with freeware or shareware programs. This is the most common method for cyber criminals to distribute Trojans and generate income.
