Vista Smart Defender. How to remove? (Uninstall guide)

removal by Ugnius Kiguolis - - | Type: Rogue Antispyware

Vista Smart Defender is a rogue anti-spyware, which aggressively seeks to make its victims download its fake licensed version. Of course, it is a paid version, which helps for hackers to generate the money. This rogue is created to infect those computers that run Windows Vista, so be aware about that and check your computer’s protection level to prevent its infiltration. In the beginning of its misleading activity, Vista Smart Defender ‘scans’ the system for viruses and starts showing continuous alerts, pop-up ads and notifications that all report about tons of them detected. In reality, this application is a useless program, which has no ability to check the system and remove those threats. If you have Vista Smart Defender on your machine, you have to remove it because it won’t stop its misleading activity.


Vista Smart Defender usually spreads via trojan horses, that exploit security vulnerabilities when trying to get inside the system undetected. Once they get inside, they begin doing their filthy job there and drop some harmless system files that additionally will be reported as viruses. Moreover, they add some registry entries for getting ability to start as soon as PC is rebooted. As a result, malware starts showing misleading alerts that keep telling you about serious security issues found. For example:

System Security Alert!
Vulnerabilities found
Background scan for security breaches has been finished. Serious problems have been detected. Safeguard your system against exploits, malware and viruses right now by activating Proactive Defence.

System Security Alert!
Unknown program is scanning your system registry right now! Identify the theft detected!
