PC performance experts offer security solution for simultaneous security and speed

iolo technologies, the makers of System Mechanic, the #1 best-selling PC tune-up product, and the fastest-growing U.S. company according to American Business Awards, announced today the launch of System Shield® 4 AntiVirus and AntiSpyware. System Shield is designed for absolute protection and maximum performance, ensuring computers are not only safe from malware and other threats, but that they suffer none of the slowdowns and performance loss so commonly experienced with other internet security products.

In what has become a feature-quantity race over the past several years, with antivirus companies choosing to compete solely on the number of new and creative ways they can detect and stop PC threats, the industry has largely neglected the significant performance impact each additional layer of protection has on users’ computers. While a small number of software manufacturers have begun to recognize this and take initial steps to mitigate the issue, iolo Labs research shows that many popular brands still slow down users’ systems as much as 50 percent, which represents an unacceptable compromise for performance-minded users.

In today’s landscape where the classic virus epidemics seen in the late 90’s and early 2000’s are increasingly rare, many experts argue that antivirus technology itself has become a commodity, and buyers should instead focus on unobtrusiveness and low resource consumption. iolo is the first to leverage its 12 years’ experience as a global leader in PC performance software to create a product that prioritizes operational efficiency from the ground up. The resulting effort has yielded very promising results, with research showing that System Shield 4 exhibits an average of less than 0.3 percent impact on computer systems tested, compared to an average of nearly 25 percent impact from several common brands.

Committed to an all-in-one yet lightweight approach to security, System Shield 4 is designed with a specific set of must-have components, avoiding the unneeded add-ons and superfluous feature lists of competing products. The four cornerstones of the product are:

  •     iolo AntiVirus™: With real-time updates, existing virus infestations are exterminated and PCs are proactively protected against any new attacks.
  •     iolo AntiSpyware™: Eradicates all forms of spyware parasites, protecting users from internet crime and restoring PC performance and stability.
  •     Sentient™ Technology: Proprietary artificial intelligence heuristics instantly recognize malicious behavior to neutralize mutations and yet-unclassified threats.
  •     HyperScan™ Technology: Exclusive, high-performance, always-on threat detection creates an impenetrable shield without any negative impact on system speed.

“Because so many internet security products slow PCs down to a crawl, many users – myself included – often opted to remain vulnerable rather than endure the hassles associated with an underperforming system. However, I’ve always believed that PC speed and security shouldn’t be a mutually exclusive experience for computer users,” said Dennis Bottrell, iolo technologies’ vice president of product technology. “We created System Shield 4 with maximum performance in mind, while ensuring complete protection from all forms of malicious programs or threats. As someone who personally demands absolute efficiency from my machines, I can honestly say that System Shield 4 is the only security program I’ve ever had installed for more than a few hours. We’ve made real believers out of ourselves.”

In order to achieve success in the design of System Shield 4, iolo challenged itself to create an effective solution that even the most sensitive gamers, artists, musicians, programmers, and other power users – including themselves – would actually use, without feeling the need to disable it in order to eliminate the lag normally associated with these products. After nearly three years of ongoing research and development, thousands of interviews with customers, friends, family, and coworkers who had all but sworn off security software due to performance annoyances, System Shield 4 is set to prove that security and speed can indeed be experienced simultaneously. With an easy to use interface and light use of resources, System Shield 4 is ideal for both novices and experts looking for a comprehensive security solution.

System Shield 4 supports both 32 and 64 bit versions of Windows 7, Vista, and XP and works on all netbooks, laptops and desktops. It retails for $39.95 and is currently available directly from iolo at, as well as from popular retail and online stores such as Target, OfficeMax, Staples, Fry’s, Fred Meyer, and In addition to its availability as a standalone product, System Shield 4’s cutting-edge technology is included in System Mechanic 9.5 Professional as a free upgrade for all users with an active iolo service plan.
