Popular system cleanup and optimization tool CCleaner has been updated with a range of improvements and a smattering of new features. CCleaner 3.15 sees support for the cleaning of a range of new applications including Freemake Video Downloader, Camtasia Studio and Ashampoo Burning Studio. As you would expect from any app update there are also a number of bug fixes as well as a small range of additional options.

In terms of new features, you will find that there is newly added support for Chrome Canary, including the ability to clear search data from the omnibox. The ability to remove items from the Recycle Bin is nothing new, but there is a new option to filter Recycle Bin deletion to only those files that were added more than 24 hours ago. This is a useful way to claw back a few extra megabytes of space while retaining the option of restoring some of the files you have deleted.

All is forgiven when there's money to be made. That's the message investors delivered Netflix CEO Reed Hastings today. Shares rallied after yesterday's earnings report, which partly validated summer's controversial streaming and DVD rental strategies that sent the stock plunging several times and led to calls for Hastings' removal or resignation. That was oh-so six months ago, which is a lifetime in the memory of an investor.

Shares rose more than 23 percent in early trading -- to $117.12. Netflix closed at $95 yesterday and opened at $114. The price reached $118.78 soon after the opening bell. As I write, shares are bobbing -- now only up 22 percent. Shareholder forgiveness doesn't vanquish Hastings' sins, however. Netflix peaked at $304 on July 13, the day after notifying subscribers of price increases. There remains tremendous share value yet to recover, which is unlikely to come from today's rally.

Putting information on the web is supposed to make it more convenient to access, but of course it doesn’t always work out that way. Especially if you’re accessing a site that is incredibly slow, for instance. Or you’re trying to download content that is spread all around the site, like multiple zip files, one each across many pages.

You may not have to put up with these inconveniences, though -- not if you’ve a copy of HTTrack to hand, as the program will automatically download the site you specify for easy reference later.

This morning, before the opening bell, AT&T announced calendar fourth-quarter earnings and record iPhone sales -- 7.6 million. Combined with Verizon's number that works out to 32 percent of iPhones sold during the quarter. Sprint will announce earnings results on February 2, conceivably pushing the number close to 40 percent. Apple CEO Tim Cook has called China Apple's second-most important market. Want to guess which is first?

For AT&T, iPhone was huge during fourth quarter. The carrier sold 9.4 million smartphones, and 80.5 percent of them were iPhones. The number was smaller, but still substantial, for Verizon: 54.4 percent. While Android sales paled by comparison, AT&T doubled them year over year -- not surprising with Samsung's aggressive marketing campaign for Galaxy S II and mid-quarter's introduction of LTE models HTC Vivid and Galaxy S II Skyrocket.

For a company which business depends on collecting data, Google sure was slow tabulating its report on smartphone usage. The study is available today, but the data is already outdated given strong holiday e-book reader and tablet sales and global impact of 37 million iPhones sold during fourth quarter -- the startling number Apple released yesterday. Still there are some fascinating trends here that likely will prove true had Google collected data in December or January rather than September-October.

What I find perplexing: 17 percent of US smartphone owners also have tablets -- 11 percent in Japan, 10 percent in United Kingdom and 8 percent each in France and Germany. Note: This data, as the rest, is for smartphones privately used. The percentages likely would be higher when including business use, and the trend is accelerating, says Google. My question, and this is really for you to answer: Why buy a tablet if you have a smartphone? Remember, Google isn't tracking PC owners who buy a tablet, but smartphones users who do.

Hewlett-Packard announced on Wednesday that it has begun the great open-sourcing of mobile operating system webOS with the release of the Enyo 2.0 core application framework.

Just a little over one month ago, HP announced it would be turning over webOS software development to the community, and open sourcing its components while participating in the project as an investor and controlling interest.

It's likely that most will expect domains belonging to popular web-based e-mail services are at the top of the list for the mountains of spam we receive everyday. That's not the case: the most common spam domains according to Chelmsford, Mass.-based security firm AVG are social networks.

Facebook tops the list at 7.3 percent, followed by Twitter at 4.2 percent. Considering these are the top two social networking sites, that's not too surprising. How about Google+? Hard to say since it doesn't have its own domain, nor did google.com appear in the list AVG supplied us. LinkedIn also appears, but way down in eighth at 1.5 percent of all spam.

The compromised website is still the most effective attack vector for hackers to install malware on your computer with 47.6 percent of all malware installs occurring in that manner, says security firm AVG. Another 10.6 percent are tricked into downloading exploit code -- many times, without their knowledge -- by clicking on links on pages to sites hosting malware.

The Chelmsford, Mass. company announced its findings as part of a broader study of threats detected by its software. It also found that faked pharmacy sites are a popular attack method, seen in about 10.4 percent of all attacks.

There are a number of tools that computer users will install by default on their Mac or PC -- an email client, web browser, media player and an office suite. Make the move to a mobile platform such as iOS or Android and the range of apps you need changes slightly. Most phones and tablets will comes with a number of apps pre-installed including a calendar, messaging tool, web browser and various other tools. One thing that is generally left out of the mix is a mobile office suite.

There are plenty of suites to choose from, but the vast majority of them cost too much and many users are disappointed to find that the app they choose to try out is too limited for their needs. Kingsoft Office is something of an anomaly -- an extremely powerful and feature-packed Android office suite that is available for free.

Mary-Jo Foley's article about a slide shown at last year's Microsoft BUILD conference raises uncertainties that bug me as a developer. It's the graphic that attempts to lay out the architecture of Windows 8, particularly in relation to Metro versus the Desktop. As a long-time Windows API programmer, I regard this graphic as the most important yet about Windows 8. Something doesn't seem right!

Somehow all the different interpretations of this chart don't make sense to me. Something's not right, especially the position the Win32 API is given. So I decided to do some digging to see if I could uncover what is really going on under the hood.

Financial software and services company Intuit launched its redesigned GoPayment Card Reader on Wednesday, after debuting the new design earlier in January. The free device plugs into a smartphone's or tablet's audio jack and lets users scan credit cards for payment.

Mobile payment systems are a hot business where lots of different standards are competing, with no clear "winner" in the space.

Online note capturing and storage service Evernote has updated its Windows client, Evernote for Windows, to version 4.5.3. Despite the minor revision number, Evernote for Windows 4.5.3 packs in a number of new features aimed at those who store PDF files within Evernote.

Also updated is Evernote for Android to version 3.5, offering two major new features -- auto-title suggestions and save anytime functions – plus improved layout of images when viewing notes.

Capturing what’s on your desktop can be as simple as hitting the Print Screen key and pasting the contents of the clipboard into an image editing app. But you’ll notice that it is not possible to capture everything; the cursor cannot be included in grabs and many dialogs disappear when Print Screen is pressed. WinSnap is a powerful screen capture tool that includes a number of handy options, with the latest version bringing support for the capturing of native Aero shadows.

WinSnap is now able to capture the shadow that is added to windows and object by Windows, but in cases where this is not possible, post-capture shadowing can be added for you. Screen capturing has many purposes, but it is often used to highlight information. To make this easier, WinSnap includes a number of annotation tools that can be used to draw shapes and arrow on your grabs as well as adding text. To the same end, there are also a number of effects to choose from. If you want to highlight a particular area of a screen capture, you can opt to grey out the rest of the image, or blur it slightly.

In case you missed it, and I certainly would have if not for someone asking a question, Apple's fiscal 2012 first quarter earnings report has a jaw dropper. iPhone generated $24.42 billion revenue. During the same quarter, all of Microsoft: $20.89 billion. More broadly, Apple revenue ($46.33 billion) was more than twice Microsoft's, and net income nearly was ($13.06 billion versus $6.62 billion, respectively). But it's that iPhone figure that really stands out. One product's revenues against an entire company's. Microsoft's margins are better, but who wouldn't want more money in the bank?

Nearly five years ago, Microsoft CEO Steve Ballmer dismissed iPhone, in a USA Today interview: "There's no chance that the iPhone is going to get any significant market share. No chance. It's a $500 subsidized item. They may make a lot of money. But if you actually take a look at the 1.3 billion phones that get sold, I'd prefer to have our software in 60 percent or 70 percent or 80 percent of them, than I would to have 2 percent or 3 percent, which is what Apple might get". How's that for the mother of wrong predictions?

Today, after the closing bell, Apple answered the question analysts have asked for weeks: How many iPhones sold during the holiday quarter? The answer: A colossal number -- 37.04 million.

Apple also shipped 5.2 million Macs and 15.43 million iPads during fiscal 2012 first quarter. Analyst consensus was around 5 million and 14 million, respectively, and 32.5 million iPhones. During today's earnings conference call, Apple CFO Peter Oppenheimer revealed 315 million cumulative iOS device sales. Apple's App Store has 550,000 applications -- 150,000 for iPad. Developers will have earned $4 billion cumulatively by the end of the month, he said.
