Kaspersky is the latest security firm to defend the importance of third-party security apps to work with Windows Vista, claiming that Vista’s new security features are unlikely to deliver long-term robust protection.

The company has published an article examining Vista’s new security features, and claims users cannot rely on them to protect their PCs.

Kaspersky’s Alisa Shevchenko looks at Vista features such as User Account Control, Patchguard and Internet Explorer 7’s security tools. She said Microsoft’s efforts to enhance security are a positive step, but not enough to remove the need for third-party security software.

One area that’s scrutinised is the User Account Control function which prompt’s Vista users for a password whenever it detects suspicious activity. However Kaspersky said that many harmless actions can be classed as suspicious, and warns that users may disable the alerts if they get flooded with password requests.

Despite the problems, Kaspersky Lab said that Vista is “undoubtedly more secure than previous operating systems from Microsoft”.
