When it comes to anti-malware utilities, a few prominent names stand out, including Norton, Kaspersky, and Sophos, in addition to some smaller and perhaps Mac-only tools like iAntiVirus and MacScan. Among the popular options for OS X is VirusBarrier from Intego, which I recently gave a spin.

VirusBarrier is offered in two versions: the basic VirusBarrier X6 package and the extended Internet Security Barrier suite that includes VirusBarrier and a number of additional utilities. I chose the latter to see what advantages it may offer over the basic VirusBarrier antivirus scanner, especially given recent malware developments on the Mac and people's interest in keeping their systems safe.… Read more

Android tops the charts in mobile malware, largely due to the failure of Google's Android Market to properly review apps before they hit the marketplace, says a new report from Juniper Networks.

In a blog post yesterday, Juniper found that Android malware has soared 472 percent since this past July. In particular, October and November have seen the fastest rise in Android malware since Google unveiled its mobile platform, according to Juniper's Global Threat Center.

The number of Android malware samples collected in October rose 110 percent over September and 171 percent over those collected up to July. … Read more

The bottom line: McAfee takes aim at blocking bots in its latest version, although weak test scores mean that we don't recommend this year's McAfee suite.

Review: McAfee released a major overhaul to its security suite back in 2010, coming up with a new vertically oriented interface that made navigating much easier. Since then, the annual updates have been incremental at best, improving the feature set yet not making substantial changes overall. McAfee Total Protection 2012 adds some new features, but these are frankly more about keeping up with the Joneses--or at least, keeping up with the Nortons … Read more

The Finnish security firm F-Secure gains a large percentage of its business from corporate accounts and platform operators, but that doesn't mean that it treats its consumer security suites as a ginger-haired child of indeterminate parentage and poor temperament. The new versions of F-Secure Internet Security 2012 (download) and F-Secure Anti-Virus 2012 (download) focus on keeping its security ahead of the curve, along with some ease-of-use improvements. However, as other suites emphasize their engine improvements along with an ever-expanding feature set, F-Secure remains steadfastly lean.

The only major visual change to the suite is the debut of the Launch … Read more

A virus that keeps a log of what people type has found a persistent foothold in the computers that pilots at Creech Air Force Base in Nevada use to remotely control the U.S. military's unmanned drone aircraft, Wired reported today.

It's not clear whether the virus was deliberately aimed at the military computers or whether it got there through the general spread of infectious malware, "but the virus has resisted multiple efforts to remove it from Creech's computers," Wired reported, citing three unnamed sources.

The Defense Department declined to comment on the matter.

The bottom line: An aggressive redesign aimed at making its best-known suite more accessible than before, Avira Free Antivirus 12 combines fast scans with above-average protection for a solid security combo.

Review: Free antivirus maker Avira debuts a laundry list of changes in its latest major update, basically repositioning the suite to remain competitive in the face of tougher competition from other free security suites and a renewed emphasis on performance from paid competitors. From the new breezy installation to the modernized interface and reputable security, the suite has a lot going for it.

However, it notably lacks some features … Read more

Optical tweezers have been used by biophysicists since their invention at Bell Labs in the 1980s, and are typically used to study cellular components. But they have a few drawbacks, not least of which are overheating and inefficiency.

So engineers at Harvard have been working on a next-gen model they call plasmonic nanotweezers to solve those and other issues with traditional optical tweezers so that tiny particles such as viruses can be isolated, observed, and manipulated.

Back at Bell Labs, scientists had shined a laser through a microscope lens to focus it tightly. They found that light, made of electromagnetic waves, creates a gradient force at the point of focus that is capable of attracting a tiny particle and holding it in that beam of light until random motion or some other force knocks it out.

The basic limitation of this approach is that a lens cannot focus that beam beyond half the wavelength of light, so if the particle the researchers hope to trap is smaller than the focal spot, they might have trouble trapping it.

Meanwhile, that focal size limit also places an upper limit on the gradient force generated, and yet a stronger force is required to trap nanoscale particles. So for a conventional optical tweezer to capture nanoscale particles, a high-powered laser is required.… Read more

When writing a weekly column about the apps business, it's easy to get caught up in the new opportunities, capabilities, and trends emerging in this burgeoning area. It's equally easy to forget they come with new threats.

These threats, which include rogue apps that can swipe your personal data or steal passwords for your bank accounts, are real and growing.

A recent study conducted by security software provider McAfee found that that amount of malicious software, also known as malware, targeting Android had jumped 76 percent since the previous quarter, a remarkable rise in just three months. At … Read more

The bottom line: Bitdefender Antivirus Plus 2012 comes with some solid basic security features, but they're more comparable to free suites than anything else. Still, Bitdefender's new AutoPilot is great for people who want top-rated security that doesn't annoy.

Review: Bitdefender Antivirus Plus 2012 presents a convincing alternative to its better-known competitors. It's a strong program, with all the major tools that users expect, and some additional useful tricks in its arsenal. Bitdefender is held back by some major problems on system performance, specifically boot up and shutdown time, so if you're cool with those … Read more
