Vista Antispyware 2010 is a name-changing rogue that also corresponds to the names Vista Antivirus 2010, Vista Guardian, Vista Antivirus Pro and Vista Internet Security 2010. What this program does is to mislead users into believing their computers are infected and then prompt them to purchase its phony full version.
Trojans, set in compromised websites, are the ones to transmit the infection. They are downloaded with a click, and the rogue infection follows right behind. When inside the machine, Vista Antispyware 2010 first creates its own registry entries that help it start automatically as soon as Windows starts. What is more, it is configured to launch automatically every time the victim tries to start a program. This configuration also gives the villain a chance to block any software from being launched in an attempt to prevent security software from detecting it.
When it is done with the installation, Vista Antispyware 2010 performs a fake scan of the system. The outcome of the scan is that a number of viruses has been detected. This is the program's biggest trick – to make the user believe that the computer is infected, which is also called a scare-tactic. Then, the rogue promotes its bogus full version as the best solution to the security problems found by the scan.
In the meantime, the program fabricates a great deal of phony alerts and notifications, which also warn about non-existing security threats. The last trump of the malware is hijacking the victim's browsers to show fake warnings when viewing webpages that are otherwise most probably legitimate. There is no surprise that the prevention method offered, when clicking on any of the alerts, is obtaining Vista Antispyware 2010.
Since everything displayed by Vista Antispyware 2010 is fraudulent, you should ignore all its prompts and remove it immediately, using a genuine anti-virus software.
