Open Notepad (Start->Run->notepad) or any simple text processor. And write this code :

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

and save with name virus.com

I prefer you to save it in desktop. Then open the the file virus.com and if your antivirus find it your antivirus is Ok and you can keep it , but if it doesn’t recognize it like a threat i prefer you to change your antivirus. Try it don’t be afraid , it doesn’t damage any part of computer.

My Antivirus caught it.. how about yours??

Well who doesn’t need a performance boost to their computer? Well may be someone who have a ‘Dell Studio’ with 4 GB ram and 1GB graphics card will laugh about performance boost…  Anyway there are people like me who need  little tweaks to speed up their system. Heres some simple steps to make your windows work faster..

There are a few unwanted “features” windows offer that eats up your CPU, they are good tools though but if performance comes above visual effects in your priority list then this trick is for you..

On Windows :

1. Right Click on ‘My Computer’ select ‘Properties’
   (Short-cut: Win Key + Pause/Break)
2. If you are using Windows Vista, Click on the ‘Advanced system settings’ on the left panel
3. Now you are in ‘System Properties’ window, click on the ‘Advanced’ tab
4. Saw the ‘Performance’ section? click ‘Settings’ next to it
   
5. In the ‘Visual Effects’ tab you can see various options to enable or disable
6. You can Disable all the effects to get the maximum performance or you could just disable the most unwanted effects
7. Heres a list of effects that wont be much of use to you :
   • Animate windows when minimizing and maximizing
   • Fade or slide menus into view
   • Fade or slide tooltips into view
   • Fadeout menu items after clicking
   • Show shadows under menus
   • Slide open combo boxes
   • Slide taskbar buttons
8. The second optional list to disable that really change the style of your Windows :
   • Use a background image for each folder type
   • Use common tasks in folders
   • Use drop shadows for icon labels on the desktop
   • Use visual styles on windows and buttons
9. You could simple select ‘Adjust for best performance’ option to disable all effects and styles

Now considering how you choose the options the system performance really changes!

Ever thought of downloading Windows Updates from their site without using ‘Automatic Updates’? If you are a ‘techie’ you must have thought of it at least once. Here is a simple way to do this :

1. Go to the Windows Update Web Site. Make sure you open it in Internet Explorer, for some reason this site wont open in any other browsers!
2. In the left panel, under Other Options, select “Personalize Windows Update”.
3. Under “Set Options for Windows Update”, select the checkbox for “Display the Link to Windows Update Catalog under ‘See Also’”, then click “Save Settings”.
4. Go back to the Windows Update web site.
5. In the left pane, under “See Also”, select “Windows Update Catalog”.
6. Select “Find Updates for Microsoft Operating Systems”.
7. Select the operating system and language of your choice.
8. Select “Critical Updates and Service Packs”.
9. Select all of the patches you’d like to download.
10. Then click on “Go to download basket” to download them..

Thats it!

Do you know? There are lots of tools that makes your life easier by configuring them in your Windows XP? But some of the cool tools are hidden by Microsoft for some reason, dont ask me why.. Anyway here are a handful of them..

To run any of these apps go to ‘Start’ => ‘Run’ and type the executable name (ie charmap).

1. Character Map = charmap.exe (very useful for finding unusual characters)

12. System Monitor = perfmon.exe (very useful, highly configurable tool, tells you everything you ever wanted to know about any aspect of PC performance, for upper-geeks only )
    
13. Program Manager = progman.exe (Legacy Windows 3.x desktop shell).
14. Remote Access phone book = rasphone.exe (documentation is virtually non-existant).

16. Network shared folder wizard = shrpubw.exe (creates shared folders on network).
17. File siganture verification tool = sigverif.exe

19. System Configuration Editor = sysedit.exe (modify System.ini & Win.ini just like in Win98! ).
20. Syskey = syskey.exe (Secures XP Account database – use with care, it’s virtually undocumented but it appears to encrypt all passwords, I’m not sure of the full implications).
21. Microsoft Telnet Client = telnet.exe
22. Driver Verifier Manager = verifier.exe (seems to be a utility for monitoring the actions of drivers, might be useful for people having driver problems. Undocumented).
23. Windows for Workgroups Chat = winchat.exe (appears to be an old NT utility to allow chat sessions over a LAN, help files available).
24. System configuration = msconfig.exe (can use to control starup programs)
25. Group policy editor = gpedit.msc used to manage group policies, and permissions

Please note that adding or editing any settings in these tools may harm your computer. Please make sure you know what you are doing..

Everybody’s favorite open-source browser, Firefox, is great right out of the box. And by adding some of the awesome extensions available out there, the browser just gets better and better.

In my case I love Firefox , its the best I think. Anyway its your choice, but please stay away from IE 6 or earlier. They are really waste to display modern sites.

But look under the hood, and there are a bunch of hidden (and some not-so-secret) tips and tricks available that will crank Firefox up and pimp your browser. Make it faster, cooler, more efficient. Get to be a Jedi master with the following cool Firefox tricks.

1. More screen space. Make your icons small. Go to View – Toolbars – Customize and check the “Use small icons” box.
2. Smart keywords. If there’s a search you use a lot (let’s say IMDB.com’s people search), this is an awesome tool that not many people use. Right-click on the search box, select “Add a Keyword for this search”, give the keyword a name and an easy-to-type and easy-to-remember shortcut name (let’s say “actor”) and save it. Now, when you want to do an actor search, go to Firefox’s address bar, type “actor” and the name of the actor and press return. Instant search! You can do this with any search box. Note : In newer Firefox you have to goto ‘Manage search engines’ then select ‘Edit Keywords’.
3. Keyboard shortcuts. This is where you become a real Jedi. It just takes a little while to learn these, but once you do, your browsing will be super fast. Here are some of the most common (and my personal favs):
   • Spacebar (page down)
   • Shift+Spacebar (page up)
   • Ctrl+F (find)
   • Alt+N (find next)
   • Ctrl+D (bookmark page)
   • Ctrl+T (new tab)
   • Ctrl+K (go to search box)
   • Ctrl+L (go to address bar)
   • Ctrl+= (increase text size)
   • Ctrl+- (decrease text size)
   • Ctrl+W (close tab)
   • F5 (reload)
   • Alt+Home (go to home page)
4. Auto-complete. This is another keyboard shortcut, but it’s not commonly known and very useful. Go to the address bar (Control+L) and type the name of the site without the “www” or the “.com”. Let’s say “google”. Then press Control+Enter, and it will automatically fill in the “www” and the “.com” and take you there – like magic! For “.net” addresses, press Shift+Enter, and for “.org” addresses, press Control+Shift+Enter. Cool right?
5. Tab navigation. Instead of using the mouse to select different tabs that you have open, use the keyboard. Here are the shortcuts:
   • Ctrl+Tab (rotate forward among tabs)
   • Ctrl+Shift+Tab (rotate to the previous tabs)
   • Ctrl+1 to 9 (choose a number to jump to a specific tab)
6. Mouse shortcuts. Sometimes you’re already using your mouse and it’s easier to use a mouse shortcut than to go back to the keyboard. Master these cool ones:
   • Middle click on link (opens in new tab)
   • Shift+Scroll Down (previous page)
   • Shift+Scroll Up (next page)
   • Ctrl-scroll up (decrease text size)
   • Ctrl-scroll down (increase text size)
   • Middle click on a tab (closes tab)
7. Delete items from address bar history. Firefox’s ability to automatically show previous URLs you’ve visited, as you type, in the address bar’s drop-down history menu is very cool. But sometimes you just don’t want those URLs to show up (I won’t ask why ). Go to the address bar (Ctrl-L), start typing an address, and the drop-down menu will appear with the URLs of pages you’ve visited with those letters in them. Use the down-arrow to go down to an address you want to delete, and press the Delete key to make it disappear.
8. User chrome. If you really want to trick out your Firefox, you’ll want to create a UserChrome.css file and customize your browser. It’s a bit complicated to get into here, but check out for this tutorial soon.
9. Create a user.js file. Another way to customize Firefox, creating a user.js file can really speed up your browsing. You’ll need to create a text file named user.js in your profile folder. You can find custom built user.js file at techlifeweb.com.
10. about:config The true power user’s tool, about.config isn’t something to mess with if you don’t know what a setting does. You can get to the main configuration screen by putting about:config in the browser’s address bar.
11. Add a keyword for a bookmark. Go to your bookmarks much faster by giving them keywords. Right-click the bookmark and then select Properties. Put a short keyword in the keyword field, save it, and now you can type that keyword in the address bar and it will go to that bookmark.
12. Speed up Firefox. If you have a broadband connection (and most of us do), you can use pipelining to speed up your page loads. This allows Firefox to load multiple things on a page at once, instead of one at a time (by default, it’s optimized for dialup connections). Here’s how:
    • Type “about:config” into the address bar and hit return. Type “network.http” in the filter field, and change the following settings (double-click on them to change them):
    • Set “network.http.pipelining” to “true”
    • Set “network.http.proxy.pipelining” to “true”
    • Set “network.http.pipelining.maxrequests” to a number like 30.
      This will allow it to make 30 requests at once.
    • Also, right-click anywhere and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0”.
      This value is the amount of time the browser waits before it acts on information it receives.
13. NOTE : I AM NOT RESPONSIBLE FOR ANY PROBLEM OCCURED DUE TO CHANGING UNWANTED SETTINGS
14. Limit RAM usage. If Firefox takes up too much memory on your computer, you can limit the amount of RAM it is allowed to us. Again, go to about:config, filter “browser.cache” and select “browser.cache.disk.capacity”. It’s set to 50000, but you can lower it, depending on how much memory you have. Try 15000 if you have between 512MB and 1GB ram.
15. Reduce RAM usage further for when Firefox is minimized. This setting will move Firefox to your hard drive when you minimize it, taking up much less memory. And there is no noticeable difference in speed when you restore Firefox, so it’s definitely worth a go. Again, go to about:config, right-click anywhere and select New-> Boolean. Name it “config.trim_on_minimize” and set it to TRUE. You have to restart Firefox for these settings to take effect.
16. Move or remove the close tab button. Do you accidentally click on the close button of Firefox’s tabs? You can move them or remove them, again through about:config. Edit the preference for “browser.tabs.closeButtons”. Here are the meanings of each value:

• 0: Display a close button on the active tab only
• 1: (Default) Display close buttons on all tabs
• 2: Don’t display any close buttons
• 3: Display a single close button at the end of the tab bar (Firefox 1.x behavior)

Charlie Miller, the hacker who discovered a hole in the new Apple Safari in ten seconds in the Pwn2Own contest, can now take complete control of an iPhone by merely sending a text message. And no, you don’t even have to open it!

Once taken control, the hacker can exploit the hole to make calls, steal data, send text messages, and do basically anything that the user can do with his iPhone. Miller and his partner Colin Mulliner demonstrated this scary scenario to CNET writer Elinor Mills at the Black Hat Security Conference on July 29, 2009. The two are professional researchers with a security firm and are just showing Apple the many security loopholes in their device.

CNET’s Elinor Mills described how it happened: “While I was talking on the phone to Charlie Miller, his partner, Collin Mulliner, sent me a text message from his phone. One minute I’m talking to Miller and the next minute my phone is dead, and this time it’s not AT&T’s fault. After a few seconds it came back to life, but I was not able to make or receive calls until I rebooted.”

The attack is enabled by a serious memory corruption bug in the way the iPhone handles SMS messages, said Miller, a senior security researcher at ISE – Independent Security Evaluators. There is no patch, despite the fact that Apple was notified of the problem about six weeks ago, he said. All current versions of the iPhone operating system are affected.

Asked what an iPhone user can do when attacked, Miller replied: “Rebooting wouldn’t be a bad idea. It would stop all but the most sophisticated attacker. However, it doesn’t take but a second to grab all your personal info from the device, and as soon as you turn it back on, the bad guy could attack you again. That’s why I think this is so serious.“

So if you have an iPhone in your pocket.. be alert!
