The company touted SiteAdvisor Plus as the first tool that will actively shield PCs from malicious websites, whether a person tries to access them through web browsing, searches, email, or instant messaging. They also claim advanced phishing protection will protect users from those scams.

The free service currently handles some 250 million requests each day to determine if a given website is safe, dangerous, or merits caution when visiting. SiteAdvisor Plus will go beyond the online version’s capacity for checking URLs, or the free download that checks search engine results for possible threats.

McAfee’s Shane Keats posted about some of the new Plus features at the SiteAdvisor blog. One feature, Protected Mode, redirects a PC to a safe page whenever the user may be heading for something deemed unsafe by SiteAdvisor.

Out of the box, SiteAdvisor Plus supports IM clients from Yahoo, Windows Live, and Google Talk. AIM support is currently in development, a strange option to be missing from the product at launch considering AIM sizable 22 million userbase.

Keats wrote that “link checking support for AIM is a top short-term priority.” Issues with integrating SiteAdvisor Plus with AIM meant either delaying the launch or sending it out with AIM support to be added later.

Likewise, SiteAdvisor Plus only supports the Internet Explorer browser. Keats noted adding support for the Firefox browser would also be a top priority along with AIM link checking.

McAfee will price a single PC license at $24.99 and a three-computer household pack for $49.99.

Vulnerability researcher Boon Seng Lim notified Symantec of the flaw, which resides in the SAVRT.SYS component of the program. An attacker could use the output buffer of the DeviceIOControl() function to overwrite kernel addresses because the address space of the output buffer was not properly validated, Symantec said, adding, “A successful exploit could potentially allow a local attacker to execute code of their choice with elevated privileges, or to crash the system.”

Symantec said the flaw could be exploited under the following scenarios:

* An attacker acquires local interactive access to a computer running the affected application.
* The attacker creates an exploit that interacts with SAVRT.SYS in a manner that triggers this issue. The attacker executes the exploit application.
* The application improperly validates the data. As a result, memory is overwritten with attacker-supplied data.

The flaw affects Symantec AntiVirus Corporate Edition 8.1, 9.0.3 and earlier versions; and Symantec Client Security 1.1, 2.0.3 and earlier.

The Cupertino, Calif.-based antivirus giant said its engineers verified the problem and released updates to address the affected products.

“Symantec is not aware of any customers impacted by this issue, or of any attempts to exploit the issue,” the company added.

As a part of normal best practices, Symantec recommends that users keep all application software and operating systems up-to-date with the latest vendor supplied patches.

A Microsoft spokesman said the software interfaces for the Windows Security Center were uploaded to a Web site for software developers.

Symantec and McAfee have accused Microsoft of abusing its monopoly in deciding which security products can run on Vista, arguing that Microsoft is deliberately withholding information needed to develop products that work on the new system.

“Despite pledges, press conference and speeches by Microsoft, the community of independent security companies that consumers rely on for computer protection has seen little indication that Microsoft intends to live up to the promises it made last week,” said Christopher Thomas, a lawyer representing McAfee in Brussels, in a statement.

Vista will be available to consumers in January.

The company will add antivirus to Blink, which started life as a host intrusion prevention system, and is planning to launch a free version of the software, albeit without the antivirus, which is being licensed from Norman AS.

eEye’s new chief executive Ross Brown told us the company’s strategy is to work as much host security functionality into Blink as it can, while at the same time not resorting to a “nickel and diming customers” pricing strategy of charging for each layer of functionality.

There are so many different types of host security product - antivirus,antispyware, firewall, application control, intrusion prevention, network access control, etc - that many believe they will all inevitably coalesce into a single deployable agent in most vendors’ cases.

Blink 2.5, the latest version, comprises application control, anti-phishing, network and application firewalls, buffer overflow protection, intrusion prevention, and removable media control.

But the company plans to go further, and outside its usual comfort zone, with the addition of antivirus and antispyware in Blink 3.0.

eEye’s product plans put it on the same trajectory as competitors such as McAfee and Symantec, which are working to reduce the number of security agents their customers need to deploy and manage on their endpoints.

But Ross said those companies’ pricing strategies involve adding license fees as functionality is added. eEye does not plan to charge extra when it adds, for example, antivirus, he said.

The antivirus will come later in the fourth quarter, in version 3.0 of Blink, Brown said. There will be “dynamic heuristics”, which detect virus-like behavior, as well as sandboxing and straightforward virus signatures courtesy of Norman, the Norwegian antivirus vendor.

Adding antivirus, now essentially a commodity, means eEye is coming at the endpoint security market from the opposite end to Symantec and McAfee, which added host intrusion prevention, application control, and other functions to their products after they had already built up large antivirus user bases.

Brown has fairly clear views on his competitors. McAfee is a sales company with decent marketing and technology, he reckons, while Symantec is a marketing firm with decent sales and engineering. He sees eEye as a company with strong engineering credentials and decent sales and marketing.

While his agenda appears to be raising eEye’s marketing profile beyond the fairly technical circles where its software already plays well, he denied the imminent launch of a free version of Blink is a direct marketing attack on rivals such as Check Point, which has a popular free desktop firewall with ZoneAlarm.

“I’m almost embarrassed to admit that the reason for releasing Blink for free is to solve an engineering problem, and not because we’re going after ZoneAlarm from a marketing perspective,” Brown said.

The reason, he said, is because “honeypots are broken… We’re seeing more targeted attacks. They’re trying to compromise 150 machines rather than thinking, How do I compromise one million?”

As all security vendors are saying, the days of the mass-mailing virus or otherwise rampant network worm appear to be over. Indiscriminate glory-boy vandals have been replaced with sophisticated criminals who so far appear to be always one step ahead of the security vendors.

They know that if their malware makes a big splash on the internet, it is only a matter of time before protection is available, so they’re getting more surrepticious.

If you can make a big pile of illicit cash compromising a couple hundred PCs here, a couple hundred PCs there, there really isn’t any need to spread an I Love You or a Slammer that would set off flashing red lights all over the internet, in the honeypots laid by the likes of eEye.

For this reason, Blink and its behavior-based zero-day attack detection will be free, so eEye can get data about new attacks from users who choose to anonymously participate. The company is calling it “neighborhood watch”, according to Brown.

“I’ll give you the corporate-level protection you need, that’s unobtrusive, that you don’t need to do anything weird with, and you give me data to make our protection better,” Brown said.

The free Blink will not include the antivirus or antispyware, he said, because those features are OEM’d, and eEye has to pay Norman when it gives its software to an end user. There will however likely be a free 90-day trial of those features, he said.

eEye is still privately held. Brown said the company is cashflow positive, but that it has yet to see the kind of annual revenue that would enable it to IPO - $80m to $100m, he reckons. That said, he reckons that an acquisition would be “not an easy buy” and would command a “large multiple.”
