Symantec antivirus software update crashes some PCs

A recent update to Symantec's antivirus software rendered some Windows-based PCs inoperable, the security software maker disclosed Friday.

An update earlier in the week to Symantec Endpoint Protection 12.1 antivirus software for businesses caused some Windows XP-based computers to crash repeatedly with a "blue screen of death," the company revealed on its Web site.

"On July 11th, 2012 Symantec Security Response started receiving reports of customers experiencing blue screens after applying the July 11th revision 18 definitions," Orla Cox, of Symantec Security Response, wrote in the post. "Machines may continue to blue screen … Read more

Facebook is now directing users who think their computer might be infected to sites where they can get free antivirus software.

Symantec takes up the iAntivirus reins

When it comes to anti-malware and security software for OS X, while tools like ClamXav and the recently released Sophos home edition for OS X are popular free options, another package that has fallen off the radar has been the relatively lightweight iAntivirus utility.

iAntivirus was originally developed by PC Tools in 2008 as a free Mac-specific antivirus tool, but the project did not last long and the latest version (1.36) was released in 2009 with no further updates. This has resulted in iAntivirus losing its relevance as a valid anti-malware tool for OS X users, and PC Tools … Read more

Norton 2013 to support Windows 8

Better firewall technology, smarter bandwidth monitoring, and Windows 8 compatibility are the hallmarks of the latest Norton betas, now available for download.

The Norton AntiVirus 2013 beta, Norton Internet Security 2013 beta, and Norton 360 v7 beta all include support for Windows 8, though the company has yet to reveal what the specific Windows 8 enhancements are. Savvy Symantec observers will note that Norton 360, usually a first-quarter release, has been moved to the company's fall schedule.

Norton has updated its firewall, too, so that it uses the suite's Insight analysis technology to detect and block suspicious Internet … Read more

Two free Mac antivirus apps compared

Recent malware attacks targeting Macs haven't tarnished the machine's reputation as the safer alternative to a Windows PC. But for many Mac users, the Flashback Trojan has dispelled the myth of Mac invulnerability.

The most recent Java-based iteration of Flashback appears to be easy to catch: just visit the wrong Web page and your machine's infected, as Josh Lowensohn describes in his Flashback FAQ.

The FAQ explains that Flashback's creators may have exploited Apple's go-it-alone strategy. Apple refuses to preinstall Adobe's Flash player, so Mac users are prompted to download and install the plug-in … Read more

Avast will introduce the latest version of its Mac security suite as early as tomorrow, just a few weeks after Flashback, the third major OS X security scare in a year.

The company touts an unblemished record of blocking the virulent malware as evidence that its suite is a must-have.

Along with an up-to-date version of the Avast antivirus and anti-malware engine and a redone interface, it … Read more

Stand behind your own Privatefirewall

Many are free, and the most popular ones do a good job keeping millions of users safe from cyber attacks, hackers, and other intrusive threats.

Its chief advantages are its intelligent tracking feature and its extensive explanations. Privatefirewall monitors your online activity privately to learn your usage patterns. It … Read more

Ad-Aware 10: Something completely different

The bottom line: The new owners of Lavasoft have revamped Ad-Aware to the point where it has almost nothing in common with its predecessors besides function. It's a good reboot, but it's not out of the woods yet.

Review: While the name Ad-Aware remains the same as it has for the past 13 years, everything from the user interface to the code powering Ad-Aware 10 is entirely new.

More so than any recent version of Ad-Aware, the suite is usable, lightweight, and worthy of your attention.

Installation The installation is straightforward, although it still does opt you in … Read more
