Vista Internet Security is a fictitious anti-spyware program seeking to trick user and infect system. This bogus program often comes along with the download and installs itself automatically. The parasite is accompanied by a malicious trojan which enters the system and then creates a backdoor for Vista Internet Security to sneak.
Malware will show you fake scan results and a large amount of various warnings about your system’s fraudulent infections. It also will offer you to purchase a supposedly legal version of Vista Internet Security program. This is a fraud and none of the information should be trusted. Do not spend your money for this scam. Just ignore all alerts and kill the parasite instead.
