PivX Solutions, Inc. of Newport Beach, California, on Monday announced the availability of Qwik-Fix Pro, an intrusion prevention
software product for Windows machines that disables or modifies features of Microsoft Corp. Windows and the Internet Explorer
(IE) Web browser that are frequent targets of malicious computer hackers and virus writers.
Qwik-Fix Pro is the first product from PivX, which made a name for itself as a security research and consulting company with
a knack for uncovering security vulnerabilities in Microsoft products. Concerned about long delays in issuing patches for
critical security holes, PivX researchers, including company founder and Chief Scientist Geoff Shively, Senior Security Researcher
Thor Larholm and Chief Software Architect Oliver Lavery, created Qwik-Fix in 2003 to protect customers and Internet users
from exploitation using dozens of unpatched IE vulnerabilities, Shively said.
The product makes temporary changes to the Windows operating system, such as changing Windows configuration settings to close
holes that hackers and worms crawl through. For example, one of the initial security fixes incorporated into the product changed
IE's configuration to prevent hackers from exploiting the standard implementation of Web surfing "zones," or sets of security
settings and privileges used by IE.
A Qwik-Fix agent can be installed and managed on Windows machines directly or remotely using Microsoft's Active Directory,
according to PivX. Once installed, Qwik-Fix Pro periodically checks an update server at PivX or in the customer data center
for new "fixes."
By shutting down little-used Windows functionality that such threats often exploit, Qwik-Fix can stop Internet worms like
Sasser, Bagle and the recent Download.ject attacks even before a virus profile or "definition" has been developed, PivX said.
More than 250,000 people have already downloaded pre-release versions of the software from PivX's Web site since September
2003, when PivX first introduced it, said Rob Shively, PivX chairman and chief executive officer.
The company will be reaching out to individuals who downloaded trial versions of the software and encouraging them to buy
the full version, he said.
The release of Qwik-Fix comes just a week after Microsoft announced the completion of Windows XP Service Pack 2 (SP2), a major
update to the popular operating system that fixes a number of security holes in the product. Given the scope of changes XP
SP2 makes to Windows, some IT vendors and analyst firms have recommended delaying deployment of the patch until compatibility
issues can be worked out.
While some of the security fixes used by Qwik-Fix are contained in the SP2 update, Qwik-Fix does not change the underlying
Windows code, as does SP2, and can be turned on and off with a single mouse click, said Chief Software Architect Lavery.
The product works with XP SP2 and older versions of Windows and is updated continuously, as PivX researchers identify and
develop "quick fixes" for vulnerabilities in Microsoft products. That will be important, as security researchers and malicious
hackers begin picking apart SP2 looking for vulnerabilities left untouched or even introduced by the patch, he said.
Qwik-Fix Pro is available immediately and costs US$60 per computer desktop and $500 per server. Volume discounts are available,
PivX said.
