The hardest part of keeping your PC secure is having to deal with the consequences of not keeping your PC secure. In this article, I have given you a handful of vital security tips and techniques that are sure to keep your system locked up tight.

One of the most important things you should do on any computer you use is make sure it’s running antivirus software. There are many free options available and many others that charge a nominal fee. Some things to look for include real-time protection and frequently updating virus definitions. These updates are typically very small, so they don’t consume many resources while downloading and installing, but they make sure your system is protected from the latest malware making the rounds.

To see a list of trustworthy programs, click Start, Control Panel, System And Security, Action Center, and then click the Find A Program Online button in the Virus Protection section. While you’re here, if it’s not already on, make sure to enable the Network Fire-wall by clicking Turn On Now.

Getting rid of sensitive files on your PC is a vital security task, and dragging them to the Recycle Bin is not sufficient.Even emptying the Recycle Bin won’t permanently destroy the file; a determined hacker could still recover it under the right circumstances. To eliminate those files once and for all, you’ll need a third-party application, like WebMinds’ Easy File Shredder ($29.95; www.easyfileshredder.com). This util-ity lets you rest easy knowing that nobody will be able to re-cover files you’ve shredded. It also protects your whole disk drive and lets you shred files on USB drives and SD cards.

Your Wi-Fi network most likely extends beyond the walls of your home or business, so unless you want anyone nearby to have access to your PCs, notebooks, or devices, you need to enable your router’s security protocols. Most routers today support WPA (Wireless Protected Access) or WPA2 encryption. WEP (Wire-less Encryption Protocol) is a much older and more vulnerable technology, but use it if you have no alter-native. Typically, enabling these protocols involves log-ging into your Router’s setup utility using a browser and the router’s IP address. Consult your router man-ual for specific instructions. Then you’ll choose your desired security type (WPA2 is preferred) and input a password. With the wireless network protected, any device that connects will need to input this password to get onto the network.

User Account Control, or UAC, is the security scheme that notifies you anytime a program or user attempts to make
changes to Windows settings or installs something. To access this control, click Start, Control Panel, System And Security,
and then click Change User Account Control Settings from the Action Center section at the top of the window. The safest
settings are Always Notify and Default, so choose either of these two. Dragging the slider to the bottom two settings is only recommended for users who run applications not certi-fied for use on Windows 7.

Security on computers is a moving target, which is why it’s imperative to keep your PC up to date by turn-ing on automatic updating. Click Start, Control Panel, System & Security, and then click the Turn Automatic Updating On Or Off hyperlink underneath Windows Update. Choose the Install Updates Automatically op-tion.

Passwords are the keys to your digital identity, and if you use a single password for all of your banking, email, social networks, and more, then you’re putting yourself at risk. Pick three or four passwords, and make them difficult to guess by including letters, numbers, and a combination of upper- and lower-case characters. Passwords of eight characters or more
are generally more secure than shorter passwords.

Hi Guys, Do you want to change the start-up tone in Windows 7 then you are at the right place. Follow the steps given below to change the default tone to your favorite tone.

Step 1: 
Choose your favorite tone with a time duration of less than 10 sec. I suggest you to choose a tone less than 10 sec because normally the windows start-up time will be less than 15 sec so the login tone should not overlap the start-up tone.

Step 2: 
If the tone is in WAV format then don’t do any change in it. Otherwise convert the tone into WAV format. Use the below link to for online sound format conversion.

Step 3: 
Rename the sound file to 5080.wav Eg: If the tone is funny.wav then rename the file to 5080.wav.

Step 4: 
Now go to drive where you installed the windows, usually (C:\). Go to the specified folder Windows>System32.

Step 5:
Find the dll file named imageres.dll in the System32 folder. Copy the imageres.dll file and paste it in the desktop.

Step 6:
Download ,install and run the dll editor software from the below link.

Step 8: 
Expand the folder WAVE>5080 and select the file 1033 present in it.

Step 9:
Go to Action>Replace other resource.

Step 10:
Select Open file with new resource button and select the sound file which you named as 5080.wav

Step 11: 
Enter the Resource Type as WAVE, Resource Name as 5080 and Resource Language as 1033 and then click Replace.

Step 12:
Now save the file (File>Save). You will see two dll files placed in the desktop, one will be the original copy and other will the newly created one(imageres.dll).

Step 13:
Copy the newly created file and go to the System32 folder. Now rename the imageres.dll file to imageresold.dll which is present in the System32 folder and paste the newly created dll file.

-Hope that this will teach you a good trick in Windows 7.Your valuable feedback is needed to improve ourselves.

Overclocking is an act of telling the processor to run at a faster speed than it was initially intended to.

Severe overclocking can cause stability issues, and in very extreme cases, damage the CPU,but usually you can gain 10 to 15 per cent extra speed without any problems.

The most common app to overclock your device is SetCPU, but the developer android app developers has recently released an easy app without lots of complex settings.

Your ROM/Kernel will need to support overclocking for the app to work.

CLICK HERE to Download and install the SimpleOC.

You will see two sliders:

The top is the max speed that the device’s CPU will run at , and the bottom is the minimum.

Reducing the max and min frequency can help save battery,but going too far will make the device laggy.

Try increasing the max by a small amount, then pressing the Menu button and settings and run the performance Test.

If all goes well,you can then try increasing the max speed some more.

Samsung Galaxy S / S2
Sony Ericsson Xperia Family
Huawei U8800 (IDEOS x5)
Milestone 1
LG Optimus One / 2X
LG GT540

-Hope this article much valuable for Android users.

Not only that, can also view website when its server was gone down, or imagine some content that was published on a website ,which was then taken down a few days later for some reason.

Now, Let us assume that your college or company has blocked access to the ‘Why this Kolaveri Di ‘ wikipedia page, but you really want to access it.

All you have to do is:

STEP 1:  Start your browser and connect to any popular search engine of your choice.
STEP 2:  Search for the blocked webpage that you wish to access.

Within the search results that get displayed, look for the relevant blocked webpage that you wish to access and click on its CACHED link below it or next to it to access its cached copy.

On google, in case you do not see the CACHED link below the search results, then you need to move your mouse over the instant preview button next to the search result and then on the right handside preview space, the CACHED link will appear.

It is also possible to view a cached copy of a site by mentioning its URL this way:

Eg: I need to view www.thehindu.com

Then I search as cache:www.thehindu.com

This will automatically display the most recent cached copy of The Hindu home page.

I’ve used it……..but HOW IT WORKS ?
All popular search engines like Google, Bing, Yahoo and others ,spider the entire Internet,recording all metadata details and keywords that appear on all pages.

This recorded metadata and keywords of all pages are then used to determine a page’s quality and rank in search results.

Along with this ,most search engines also take a snapshot of all webpages on Internet and store a cache copy of them.

And this becomes an extremely usefull one for us, and it is a simple but clever trick of fooling local firewall, bypassing any basic filters ! Of course, I use this to watch a cached copy of a site, which has been blocked by my college’s Sonic Firewall.

The Cloud print service from Google makes it possible for PC users to wirelessly print to a networked printer from smartphones,
laptops, and tablets capable of supporting Google services, such as Gmail or Google Docs and even the Google Drive, which makes us to experience the Software as a Service(SaaS) of the Cloud.

Unlike Apple’s AirPrint, which works over the local Wi-Fi network and currently requires an AirPrint-compatible printer, Cloud Print sends your print jobs via the internet.
To get started, you’ll need to Connect your printer to Google Cloud Print.
To get your own Google Cloud Print, follow these simple steps.

Google Cloud Print supports a number of flavors of Windows, including XP, Vista, and Windows 7. No matter which version of Windows your rig is rocking, you’ll need to have Google’s zippy Chrome browser installed on your PC in order to leverage Google Cloud Print. You can find it at www.google.com/chrome. The computer on which you install Google Cloud Print needs to be connected
to the same network as the printer you want to print from. Before moving on to Step 2, open Chrome and turn on your printer.
You will also need a Google account
to continue, which you can create at www.google.com/accounts.

Look for the wrench icon in the top-right corner of the Chrome window.
Click it, and from the menu that opens up, select Options. This will open the Options pane. From the Options pane, click the tab
labeled Under the Hood and scroll to the bottom of the available options (image G).
Click the button marked—you guessed it—Sign in to Google Cloud Print.
Now, sign in using your Google Account credentials.

If everything goes according to plan, you’ll be rewarded with a window telling you that the operation is a success.
That same window has a button prompting you to print a test page.
Give it a click. In doing so, Chrome will open a new browser window that prompts you a second time to Print a test page.
Select a printer or a service and click Print (image H).

Now that you’ve set up Google Cloud Print on your home computer, you’re ready to start printing on the fly from your smartphone or other Internet-connected mobile device.
Grab your mobile computing device of choice and navigate to Google Docs(or Google Drive). Select a file.
From the menu bar at the top of your Google Docs interface, click the Option button (located to the left of the Refresh button), and then tap the Print link.
Doing so will open a new browser window that reflects the same printer options as were offered on your networked computer back at home (image I).
To print your Google Docs file, select a printer, set your print options if need be, and watch as Google Cloud Print does its thing.
Provided you left your computer at home on with Chrome up and running, your print jobs will be sent from mobile device back to
your computer.
If you turned your computer off before leaving home or the office, turn it back on when you return and open Chrome.
Your documents will be sent to the printer of your choice in short order.

Hi guys, I’ve seen many colleges and companies, don’t allow Instant messengers to be installed in your systems due to security, privacy and confidentiality reasons and installations are strictly blocked by their system administrators.

But if you are like me and cannot live without chatting with your friends even for a few hours, then a very good alternative is to use something known as Web messengers.

Almost all Instant messengers have an online web interface that allows you to chat with your friends from within your browser itself without the need to download and install any instant messaging application on your machine.

There are also third party web messaging tools available that are compatible with all popular instant messaging platforms.

Some of the most poplular websites thtat allow you to continue chatting with your friends using just your browser are:

Google Talk  :  http://www.gmail.com

http://www.google.com/talk

MSN Messenger :  http://www.webmessenger.live.com

Yahoo Messenger : http://www.messenger.yahoo.com/web

IMO  :  https://imo.im/

eBuddy : http://www.ebuddy.com

Here IMO and eBuddy supports MSN , Skype , Yahoo , Google , Facebook , AIM , ICQ , Jabber and many others.

All you need is to go to the site and select your network and get logged in.

Have you lost your admin password, here is a simple way for you to recover it.

This works till the latest Precise pangolin (12.04) version of Ubuntu.

root @ubuntu:~#
At this stage it is possible that ,you might have setted-up a read-only filesystem. You have to remount it with write permissions:

Now we can set the user’s password with the passwd command. (In this example I will use badhri as the example, you need to substitute whatever the user’s username is):

Type in what you want the new password to be at the prompt. After it’s successful reboot the machine and the user will be able to log in with their new password.

-Hope this is much useful for Linux Lovers……
( WARNING: Never try this for cracking any admin’s password).
