As part of its monthly Patch Tuesday, Microsoft released five security bulletins, none of which are critical, plugging 15 holes. Affected software includes Windows, Office, Excel, SharePoint, Windows Server, and Office Web Apps.

Microsoft has rolled out a new update for Internet Explorer 9 that fixes a host of different security holes.

Launched yesterday on Microsoft's familiar "Patch Tuesday," the August 2011 Cumulative Security Update for Internet Explorer is a critical one that resolves issues not just in IE9 but in versions 6, 7, and 8 as well, according to a Microsoft blog. The update is available through Windows Update, so IE users who have Windows automatic updates turned on should have already received it.

It's easy to assume the important programs on our systems update automatically, but not all do. Some outdated apps can be security risks. I compared three free scanners that promise to identify programs in need of an update: Secunia's Personal Software Inspector (PSI), CNET's TechTracker, and KC Softwares' Software Updates Monitor (Sumo).

I'm not linking to Sumo because when I tested the program, it installed the Relevant Knowledge spyware along with the scanner even though I purposely chose what the company claimed was the spyware-free installation file.

PSI IDs more apps, provides plenty of update info … Read more

Windows 7 is four to five times less vulnerable to malware infections than is Windows XP.

Those are the findings of Microsoft's latest Security Intelligence Report (PDF), which detailed in depth the state of software vulnerabilities, exploits, security breaches, and malware in 2010.

Overall, the study found that infection rates for newer Microsoft operating systems with the latest service packs are consistently lower than those for older OSes, giving Windows 7 and Windows Server 2008 R2 the highest marks for security.

Looking at the number of reported infections per 1,000 computers, Microsoft found that Windows 7 64-bit had … Read more

Microsoft today fixed a critical hole in Windows and two less serious holes in Office in one of the lightest Patch Tuesdays in recent history.

It affects Windows Server 2003 and 2008.

WINS is not installed on the affected operating system software by default, so only customers who manually install it are affected and will be offered the … Read more
