Malware writers seem to be targeting the Task Manager with increasing frequency. McAfee's Avert Labs wrote in its blog yesterday of the discovery of a new Trojan it dubbed QTaskMgr-1, which crawls into the registry and disables the Task Manager, Windows Update and Internet Explorer tool bars. Hitting Ctrl+Alt+Del will activate the Windows Security menu, but all functions including Change Password and Lock Computer are disabled.

In reviewing several security articles and blogs about malware characteristics and workarounds, I see a recurring piece of advice: Don't click on any popup or dialog window; instead use the Windows Task Manager to end offending processes. It's good advice, since malware writers-particularly those spreading scareware or bogus applications designed to trick computer users into buying useless security software-are gaming the dialog windows. Users are often presented with the typical option, such as "do you wish to proceed? Yes/No." Hitting either button or even the "X" window closing button will initiate a background process as if the user agreed. Using the Task Manager is the safe way of disabling these processes to allow the anti-virus software to scan and remove the offending code. Or so we think.

The NSW Department of Education is using asset-tracking software, RFID tags, and BIOS-embedded filtering smarts to roll out 240,000 netbook computers into what CIO Stephen Wilson calls "the most hostile environment you can roll computers into" - the local high school.

Emerging as the sentinels of this modern scourge are companies like WatchGuard, the Seattle-based manufacturer of appliances dedicated to inoculating computer networks from the spread of viruses. The company in November unveiled three new models in its XCS series of 1U appliances to provide small and midsize businesses with always-on protection from spam, viruses, spyware, phishing and other threats borne by e-mail.

Hackers are increasingly targeting law firms and public relations companies with a sophisticated e-mail scheme that breaks into their computer networks to steal sensitive data, often linked to large corporate clients doing business overseas.

A panel of CIOs from state government, health care and the insurance sector told cloud providers from Microsoft (NSDQ:MSFT), Google (NSDQ:GOOG), Amazon (NSDQ:AMZN) and Joyent on Thursday that they no longer need to be sold on the benefits of cloud infrastructure -- they get them. But that doesn't mean they're ready to trust the cloud, either.
