Windows/Linux: Sleeping your computer is a useful way to save energy, but free utility SonarPM takes power management an awesome step further: It puts your computer to sleep automatically when you walk away from your desk—using sonar.

Almost any computer with speakers and a microphone can take advantage of this software, so most laptops are good to go. It works by emitting an inaudible frequency from your speakers, and detecting echoes with your microphone, determining whether you are sitting at your desk or not. If you get up, your computer will see that you have done so and automatically put your computer to sleep. Sure, you could always just use a hotkey, but this requires literally no energy on your part—and it’s sure to be a heck of a conversation starter.

The program is open source, so if you’ve got some tinkering skills, you can make it do all sorts of things when you walk away (as described in the video above by Tinkernut). If you just want the sleep functionality, you can still download and install the package and use it as-is (if you’re a Windows user, that is—Linux users need to compile from source—check the instructions on the site if you need help doing this). It doesn’t necessarily work with every microphone and speaker equipped computer, so test it out to see if it does with yours—you may need to calibrate it a few times before it works well (it took me a few tries and a little bit of waiting afterward before it started working in Windows on my MacBook Pro).

Sonar Power Manager is a free download for Windows and Linux systems. Sleeping your computer whenever you walk away seems a little heavy handed (do I really want to put my computer to sleep when I’m going to get a glass of water?), but the possibilities are endless, and if you are interested in bending it to your will, Tinkernut’s guide is an excellent place to start.

OK, OK, I know there are many free anti-virus software available out there. We have Microsoft Security Essentials and AVG as 2 fine examples of great free anti virus software

Some of you may want to pay for anti virus software because you believe that you will be better protected, and that’s fine. That’s a personal decision. However, it’s not necessarily the case at all, I used AVG free and AVG pro, never got a virus with either. I used Kaspersky which is not  free , however Microsoft Security Essentials did the job just as well and is free.

Well, I’d like to now bring your attention to Avast Free 5.0!

Yes as it’s name suggests it’s free and yes there is a pro version you can pay for if you wish.

The Key Components that compile this latest version according to Avast are:

1. Improved anti virus and anti spy ware engine
2. Avast Intelligent scanner
3. Silent/Gaming Mode
4. Behavior Shield
5. Real Time Anti Root Kit Protection
6. Smart Virus Updates
7. Avast Community IQ
8. Behavioral Honey Pots
9. Green Computing
10. Avast I-Track
11. File System/Mail Shield
12. IM/P2P Shield
13. Network Shield

Lifehacker also brought out that this latest version brings a new Behavior Shield, heuristics engine and code emulator.

Many of you who are familiar with Avast will be pleased to hear about some major improvements. You will notice that the Interface has greatly improved in terms of it’s ease of use. The new interface is much more simple to use, and is that bit easier on the eye.

Also you will notice that scans run faster than the previous versions, which in turn makes it more efficient.

On one final note, you will notice as i mentioned above, that it has a Silent/Gaming mode. So, no more distracting pop ups and voices that close your game down involuntary.

I would seriously recommend this latest anti virus, whether you use an older version of avast, or perhaps you’ve never before used Avast, or perhaps you have used Avast, and have then changed to a different anti virus software. Either way I am making a serious recommendation, at least just try it, if you don’t like it, then simply uninstall it. Although you will need to give serious consideration before doing this if you are using a paid for anti virus as you may lose your license. (READ – Backup your licence)

To Download Avast 5.0 just click here.

I would very much appreciate your comments below, it really does help to get other peoples opinions. You could mention what you like about it, what you don’t like. Or even you could note your preference of anti virus and why. You see when other readers voice their opinions it gets other readers thinking about programs that they don’t use, so they will try them out. Its only by sharing our opinions that information gets around, and in turn benefits us all.

Windows only: Fishbowl, the Facebook client demoed at Microsoft’s introduction to Silverlight 4, is now available for download—and it adds quite a few new desktop features to the Facebook experience, including badges, a mini news feed, and more.

At first glance, Fishbowl looks a lot like a reorganized, slightly better looking version of Facebook. Along the top you have the usual sections of Facebook—Home, Profile, Photos, etc.—and on the left sidebar you have options for the window you’re in. Navigating these sections is just like Facebook’s web site, so it’s pretty intuitive.

Buying, installing, and upgrading

• 
• Figure Out Which Windows 7 Edition Has the Features You Need: Not everybody needs Windows 7 Ultimate, but what if there’s a certain feature you must have when you grab your upgrade this Thursday? CNET breaks down each Windows 7 edition feature by feature in a handy chart.
• Prep Your PC for Windows 7: When Windows 7 drops this Thursday, you can either spend many, many hours watching a progress bar, or you can boot into a clean, speedy system with that new-OS smell. Let’s get your system set up for a proper Windows 7 upgrade.
• Get Windows 7 Home Premium for $30 With a College Email Address: If you’re a U.S. college student, or at least having a working .edu email address, you don’t have to pay $120 to upgrade Vista to Windows 7. You can get the Home Premium upgrade for just $30.
• Run Windows 7 for 120 Days Without Activation: The command line code (slmgr -rearm) that could be entered at the end of three different 30-day periods to give Vista 120 days without activation works just the same in Windows 7.

Our take on Windows 7

• Top 10 Things to Look Forward to in Windows 7: Windows 7 isn’t a dramatic overhaul of its predecessor Windows Vista, but it does fix several sore spots and add a few welcome features.
• Windows 7′s Best Underhyped Features: It’s these less sexy, but very useful features, that make me think the more I use Windows 7, the less chance I’ll ever use Vista or XP again.
• Windows 7 Versus Mac OS X Leopard: The Feature-by-Feature Showdown: Oh, I know: the Mac versus PC debate is so played out. Perhaps, but dumb commercials aside, if you’re deciding between buying a Mac or a PC in the coming months, it helps to know what you’re getting from one or the other.

New features

• Windows 7 Tells You Why You Can’t Touch That File: Windows 7 doesn’t just give you a wagging finger (and pretend-useful “Try Again” button) when you want to move or delete a file that’s in use. It actually tells you which application is using the file.
• Windows 7 Lets You Customize Your Logon Background: Expert Windows hacker Rafael Rivera finds a change in the latest build of Windows 7—you can finally customize the log-on screen natively.
• Windows 7 Transfers Your Wireless Settings Easily: To transfer the settings for yourself, head into the Network and Sharing Center, click on Manage Wireless Networks, and then in the properties for your wireless network you’ll find the link to open the wizard that will copy all your settings onto a flash drive.
• How to Burn ISOs in Windows 7: Burning that ISO to a disc is as simple as: 1. Double-click the ISO file (or right-click and select Burn disc image); 2. Click Burn.
• Play Your iPod Through Your Windows 7 PC’s Speakers: You can play an external audio device through your computer’s speakers without any extra software using a simple configuration setting.
• Windows 7 Makes UAC Less Annoying Than Vista: The biggest change in Windows 7 is the new User Account Control “slider” setting, where you can choose your own balance between annoyance and security—but behind the scenes, Microsoft reduced the amount of actions that will prompt you.
• Netflix Update Comes to Windows 7 Media Center, Looks Excellent: Starting this week, Microsoft is rolling out an upgraded Watch Instantly interface to Windows 7 Media Center for users looking to get their streaming TV and movie fix on their upgraded PCs.
• Setup File and Printer Sharing From XP to Windows 7: This guide walks you through the process of enabling network discovery, sharing your folders and printers, and accessing your shared resources from either Windows 7 or XP.
• IE8 Can Proactively Close Crashing Tabs in Windows 7: The copy of IE8 found only in (Windows 7) has a “timer” that monitors new tabs as they open. If they aren’t responsive within a relatively short amount of time, the browser will pop up and tell you this, possibly with a reason why, and ask whether you want to wait or kill the tab before it causes further problems.
• Windows 7 Lets You Finally Uninstall Internet Explorer (Kinda): … It won’t completely uninstall—only the executable is actually removed. Still, being able to finally banish IE proper from your system is a pretty good start for folks who really don’t like IE.
• Windows 7 Will Let You Uninstall Most Built-In Apps: You can turn almost every built-in application on or off, including Windows Search, Gadgets, and even Media Player.

The Taskbar

• Aero Peek: Peek supercharges Windows’ taskbar thumbnail previews, and lets you view, close, and switch between multiple windows by just hovering over the taskbar thumbnail, as well as pin programs to the taskbar permanently.
• Pin Individual Folders to the Windows 7 Taskbar: Windows 7′s taskbar lets you pin any running program to the taskbar for easy future access, but it treats folders like second-class sub-items of the Explorer icon. Create a fake “program” to pin individual folder shortcuts to your taskbar.
• Middle-Click to Close Applications from Windows 7′s Taskbar: In Windows 7, middle-clicking a taskbar button opens a new program instance. The easy solution for closing an app? Middle-click its preview window.
• Hold Shift While Dragging to Windows 7 Taskbar to Open Files: All you have to do is hold down the Shift key while dragging a file to an icon on the taskbar, and the tooltip will change to say “Open with” instead of pinning to the taskbar.
• Pin Any Item to the Windows 7 Taskbar: We already showed you how to pin specific folders, and this is just a slightly tweaked application of that method.
• Put a Recycle Bin Shortcut on the Windows 7 Taskbar: Once you are finished, you’ll have a separate recycle icon on the taskbar—useful for quick access to deleted files without having to hunt down an icon on your desktop.
• Get a Functional Recycle Bin on Windows 7′s Taskbar: TechSpot’s solution—creating a Quick Launch taskbar, removing its text and title, then bringing the desktop Recycle Bin icon into it—covers all the bases, and lets you place your Recycle Bin pretty much wherever you’d like on the taskbar.

Jump lists

• 
• Master Windows 7 Jump Lists to Boost Your Win7 Productivity: For those of you that haven’t yet tried out Windows 7, when you right-click on a taskbar button in Windows 7, a menu slides out with recent documents and application tasks. Here’s a rundown of our favorite Jump List boosters.
• Winfox Adds Jump Lists to Firefox on Windows 7: Jump Lists are one of the best new features in Windows 7, and since Firefox still doesn’t take advantage of them, a small utility called Winfox adds the feature for you.

• Calculator: While mathletes, scientists, coders, and statisticians will appreciate Windows 7′s built-in calculator’s programmer, statistics, and scientific modes, everyday people will love figuring out things like hourly wages and mortgage payments without a spreadsheet.
• PowerShell: (A) souped-up command line and scripting GUI that frees you, finally, from the limits of DOS batch scripts.
• Windows 7 Media Center’s Music Player Is Hot Hot Hot: Good news for music lovers excited for Windows 7: The new and improved music interface in Windows 7 Media Center is overflowing with eye candy and usability.
• Windows 7′s WordPad Opens Word 2007 DOCX Files: … The ribbon-style WordPad in Windows 2007 opens Word 2007 files, the .docx kind, pretty handily, albeit with some formatting loss.
• Backup and Restore Center: For the average user with both media and crucial file needs, Windows 7′s default backup features look promising.
• Windows 7 Guest Mode Creates Bomb-Proof Accounts: In the simplest terms, Guest Mode takes a snapshot of how a PC was working before the kid, friend, coffeeshop customer, or whoever else is using the Guest Mode account logs on. That user can’t do much to alter the system, and whatever they can do, like dropping files on the desktop, is discarded when they log off.
• Windows 7 Calibration and ClearType Tools Fine-Tune Your Displays: Windows 7′s color calibration and ClearType tools might be good enough for non-graphic-designers to stick with.

Mouse and Keyboard Shortcuts

• The Best New Windows 7 Keyboard Shortcuts: Windows 7 has more cool new shortcuts than you can shake a stick at.
• Aero Shake: When you want to focus on the task at hand on a desktop cluttered with windows, just grab the window bar of the app you want to work in and shake it back and forth to clear away the rest. Another shake will restore the background apps to their former state. You can also drag and drop a window to the edge of the screen to maximize it, and click on its top bar again to restore its previous size.
• Snap windows to half screen size: … Dragging a window to the top of the screen maximizes it. Following that, if you drag a window all the way to the left or the right of the screen, Windows 7 will display a glass overlay on the desktop. Let go of the mouse button and it will snap the window onto that overlay, which is half the screen’s size—a handy helper for widescreen monitor owners.
• Maximize Windows Vertically with a Double-Click in Windows 7: Reader John points out that you can simply move your mouse to the top of a window until the pointer switches to the resize icon, and then double-click your mouse to instantly maximize the window to fill all the available vertical space.

Tweaks, fixes, and customizations

• Customize or Disable Windows 7′s Action Center: Windows 7′s Action Center does a great job of compressing all of Windows’ update/alert/whatever notifications into one icon, but it takes some tweaking to make it show what you want, or disable it entirely.
• Add text to the Windows 7 taskbar buttons: Just right-click the taskbar, select Properties, then change the Taskbar buttons drop-down from “Always combine, hide labels” to “Never combine.”
• Set Default Printers Based on Network in Windows 7: Windows 7 sports a great new feature that allows you to set default printers based on what network your computer is connected to, perfect for folks who carry laptops from network to network.
• Get Quick Access to Windows 7′s Jump Lists From the Keyboard: When we showed you how to master Windows 7′s new Jump Lists feature, there was one extremely useful tip that we left out: you can also access them from your keyboard.
• Create and Share Custom Themes in Windows 7: Microsoft’s Engineering Windows 7 weblog details how to create, save, and share your own custom Windows 7 themes, complete with wallpaper, window color, and sounds.
• Get the Old “Show Desktop” Back in Windows 7—Kinda: The short version: Create a folder, place a “Show Desktop.scf” file in there (either your standard Google-found kind or the script available at the bottom link), then right-click your taskbar to create a “New Toolbar” that points to that folder. Turn off the text and titles on that new toolbar, change the icons to large size, and then put your new one-button toolbar where you’d like.
• Hidden Windows 7 Tool Troubleshoots Sleep Mode Problems: The report lists all of the devices that are causing problems with sleep mode, explains the different power saving modes your computer supports, and even gives you detailed information on your battery—invaluable information when your system takes forever to go in and out of sleep mode.
• Disable the New Libraries Feature on Windows 7: Simply download, extract, and double-click on the provided registry hack file, then restart your computer and you’ll see that the Libraries are completely gone. There’s also an uninstall registry script provided just in case.

Third-party helpers

• Logon Changer Customizes the Windows 7 Login Screen: Tiny system customizing utility Logon Changer for Windows 7 swaps out the logon screen wallpaper easily. Using the utility is simple—just select a new wallpaper, test it, and you are done.
• Xdn Tweaker Updates to Tweak Windows 7: If you want your system to remember or not remember how you sort certain folders, edit what’s accessible through the right-click menu, or de-hook Windows Media Player from all the files it tries to glom onto, Xdn does those things for Windows 7.
• Glass CMD Enables Aero Transparency for the Command Prompt: Glass CMD for Vista forces command prompt windows to use Aero’s glass transparency effect.
