Security basics for beginners:

Everyone of us wants a virus/malware free computer that works fast, therefore we install a good anti-virus or purchase a new software for malware removal and pay handsome amount of money for it too. But we forget that only an anti virus is not enough for complete PC security!
Security against hacker also included in this post-



1. Check Windows Update and Office Update regularly; have your windows/ Office CD ready. Windows users can configure automatic updates. Click on the Automatic Updates tab in the System control panel and choose the appropriate options.

2. Install a personal firewall. Both SyGat and ZoneAlarm offer free versions. If you have windows 7 then the windows firewall is also good enough. 

3. Install a free spyware blocker.

4. Block pop-up spam messages in Windows XP, vista, 7 by disabling the Windows Messenger service. Open Control Panel | Administrative Tools | Services and you'll see Messenger. Right-click and go to Properties. Set Start-up Type to Disabled and press the Stop button. Bye-bye, spam pop-ups! Any good firewall will also stop them.

5. Use strong passwords and change them periodically. Passwords should have at least seven characters; use letters and numbers and have at least one symbol. A decent example would be k7irtro#2. This will make it much harder for anyone to gain access to your accounts.

6. If you're using Outlook or Outlook Express, use the current version or one with the Outlook Security Update installed. The update and current versions patch numerous vulnerabilities.

7. Buy antivirus software and keep it up to date. Or download a free version of any of the Windows recommended anti-virus, i prefer AVG, AVAST, NORTON but you can download any.

8. If you have a wireless network, turn on the security features: Use MAC filtering, turn off SSID broadcast, and even use WEP with the biggest key you can get.

9. Be skeptical of things on the Internet. Don't assume that e-mail "From:" a particular person is actually from that person until you have further reason to believe it's that person. Don't assume that an attachment is what it says it is. Don't give out your password to anyone, even if that person claims to be from "support."

7 totally useless but interesting twitter apps!


  1. THREETUNE:
                                              
    Click on the cookie and it generates a random tweet for you. If you are bored while tweeting then try this app out, but hey, careful, some tweets may be offensive.


  2. TWONVERT:
                                  

    Write your tweet in the left hand side window and it will automatically be converted to shorthand.! save your time and again its useless but interesting ;)


  3. TWITTERLOO:

                                             
     This is a funny (and useless) app that is a "must try". Whats in it?? I will let you try that yourself :D


  4. FOAMEE:

                                              
     Its an online pub for twitter users, you can send a virtual BEER or COFFEE with a tweet. LOL! try it out..


  5. Zzzz:
                                        
    It’s one of our favorite words in the English language and this visualization app takes advantage of it in an artful way. It searches for tweets containing the words ‘Zzz’ or ‘Zzzz’ and then generates it as shown in the screen above in real time. It’s a simple visualization project and is not intended to put you to sleep :D


  6. TWEET WASTERS:

                                       
     You simply put twitter username and it shows you how much time that person wastes while tweeting :D


  7. THE PRINT EFFECT:

                                     
    Enter your twitter username, and it would tell you- HOW MUCH WOULD IT TAKE TO PRINT YOUR ENTIRE TWITTER TIMELINE :)

    Cool PC pranks to scare the hell out of your friends :D



    Alright, this time i m sharing some funny fake viruses and pranks which can be used to annoy your friends anytime :D 



    1. This one will make your CD-DRIVE open and close automatically and will stop only when you restart your system :D --
      Save the following in your notepad-

      set oWMP = CreateObject("WMPlayer.ocx.7") 
      Set colCDROMs = oWMP.cdromcollection 
      do 
      if colCDROMs.Count >= 1 then 
      For i = 0 to colCDROMs.Count - 1 
      colCDROMs.Item(i).Eject 
      Next 
      For i = 0 to colCDROMs.Count - 1 
      colCDROMs.Item(i).Eject 
      Next 
      End If 
      wscript.sleep 100 
      loop 


      Now click SAVE AS, select ALL FILES and save it as .vbs. You will notice another new file on the saved location, thats vbs file, open it to start the prank! :D It can get really annoying so do it before you shutdown to try it out, and wait for a friend to open it next and see what happens. Its more annoying than it is scary :P (TIP: you can change the icon of the vbs file to any other icon to make it more interesting )

    2. Fake virus batch file--
      copy the following code in notepad and save it as .bat file...

      cls
      :A
      color 0a
      cls
      @echo off
      echo Wscript.Sleep
      echo Wscript.Sleep 5000>C:sleep5000.vbs
      echo Wscript.Sleep 3000>C:sleep3000.vbs
      echo Wscript.Sleep 4000>C:sleep4000.vbs
      echo Wscript.Sleep 2000>C:sleep2000.vbs
      cd %systemroot%System32
      dir
      cls
      start /w wscript.exe C:sleep3000.vbs
      echo Deleting Critical System Files…

      echo:
      echo Creating Directory h4x…
      cd C:Documents and SettingsAll UsersStart MenuPrograms
      mkdir h4x
      start /w wscript.exe C:sleep3000.vbs
      echo Directory Creation Successful!
      echo:
      echo:
      echo:
      echo Execution Attempt 1…
      start /w wscript.exe C:sleep3000.vbs
      echo cd C:Documents and SettingsAll UsersStart MenuProgramsStartuph4x
      echo start hax.exe
      start /w wscript.exe C:sleep3000.vbs
      echo Virus Executed!
      echo:
      echo:
      echo:
      start /w wscript.exe C:sleep2000.vbs
      echo Disabling Windows Firewall…
      start /w wscript.exe C:sleep2000.vbs
      echo Killing all processes…
      start /w wscript.exe C:sleep2000.vbs
      echo Allowing virus to boot from startup…
      start /w wscript.exe C:sleep2000.vbs
      echo:
      echo:
      echo Virus has been executed successfully!
      start /w wscript.exe C:sleep2000.vbs
      echo:
      echo Have fun!
      start /w wscript.exe C:sleep2000.vbs
      pause
      shutdown -s -t 10 -c “Your computer has committed suicide. Have a nice day.”

      Here’s how it will look like once it is launched:

                              



      PC will show messages as in the above image, and then initiate a shutdown sequence which can be stopped by entering “shutdown ““a” in the Run command box. It looks bad, but is otherwise completely harmless. :)

    3. EICAR test file:
      This is a test file created for the sole purpose of testing an anti-virus software weather its running successfully or not. But this can be used as a prank EMAIL to scare your friends :D This file will make almost all anti-virus programs to warn the user and scare the $#!t out of him :D
                                   
      HERE'S THE DOWNLOAD LINK OF THE EICAR FILE: DOWNLOAD HERE

    4. FAKE FORMAT PRANK:
      this one is one of the best and will definitely give goosebumps to your victim :D
      This cool fake virus perfectly simulates the Windows disk-format dialog, and cannot be closed or halted until it’s ran its course. Once it’s done, a message will be displayed informing the user that it was just a joke! DOWNLOAD HERE.

    5. Last but not the least, this is meant for those who really are a bad-ass :D This is kiddish but funny! Ok, its called "YOUR MOUSE IS NOT YOURS ANYMORE :P "
      Simply put a tape over the laser sensor of the mouse :D BINGO!!!

    Convert USB to bootable flashdrive to boot windows XP!

    Step 1: Download the File from the link given below:
    Size: 499KB
    Name:  usb_boot_prep_xp.zip
    Password: techrena.net

    Step 2: Extract the usb_boot_prep_xp.zip file in your C drive. It will give you two folders named bootsect and usb_prep8. Plug in your USB drive to your computer and put the Windows XP CD also.
    Step 3: Go to the usb-prep8 folder and double click usb_prep8.cmd file. Press any key to continue.

    Step 4: Now it will open PeToUSB. Format your USB drive using it. Select the options as in the image below. Note that after formatting do not close the PeToUSB or the cmd console.

    Step 5: Now open a new cmd console manually (press Start+L, type cmd and enter). And type the following command in the commands prompt. Note that you should type your own USB drive letter instead of ‘h’.
    Sl. No.
    Command:
    Action:
    1
    cd
    Enter
    2
    cd bootsect
    Enter
    3
    bootsect.exe /nt52 h:
    Enter

    I had copied the folder in D drive. So the image will be somewhat different with the actual display of your console. Don’t worry copy the folder in your C drive only. Now close this cmd console but not the other one.
    Step 6. Close PeToUSB. Now the usb_prep8.cmd console will continue. Select 1 to set the source location. Select the CD ROM containing the XP CD.


    Step 7: If you have a drive called T in your computer then check option 2 to change it to any letter which is not present. Otherwise no need to change. Select 3 to set the destination drive. Enter your USB Drive letter as shown below:

    Step 8: Now select choice 4 as we don’t have any Tempimage previously. It may ask you to delete the existing tempimage. select Yes.
    Step 9: It will ask you to format the T drive. Enter y and it will format your temp drive. Press any key to continue. Now it will start copying the XP files to the tempdrive.
    Step 10: After the completion of the file copy process Press any key to continue. Now it will ask you to copy the files to your USB drive or not. Select Yes.

    Step 11: During the copy process it will ask whether to change migrate.inf file or not. Is you are using a USB stick then Select Yes. If you are using a USB hard drive then Select No. 
                                            
    Step 12: After the successful completion of copying the files to your USB drive it will ask whether to unmount the Virtual temp drive or not. As you do not need it Select Yes.
    Step 13: After the successful completion of the process close the cmd console. Now your pen drive is ready for the installation process.
    Step 14: Plug in the USB drive to the computer you want to install XP. While start up make sure that you set the first boot choice as your USB drive. To do this you have to enter to the bios and change the boot order to USB Disk as the first choice. For entering to BIOS  press the BIOS setup key while start up. This key is usually seen in the screen in the boot screen. For most of the systems it is DEL key. For HP and Compaq it is F10 etc. Go to the boot configuration tab and change the boot order.
    Step 15: While booting up from the USB it will ask you to choose between GUI and TXT mode of setup. Select TXT mode for now.

    Step 16: Follow the onscreen instructions. It is same as the usual setup process. In the partition selection screen do not select you USB drive for install. And if you are installing in a new RAW hard disk then your USB Drive will be the C drive. Now first create a new partition and format your HDD using the setup. And again restart the process from step 15 by Quitting the current Install(Press F3). Then you should get your HDD partition as C drive. Continue your installation.

    Step 17: Now it will copy a set of files to the hard disk. It usually takes lesser time than a CD ROM installation. After the process it will ask for reboot. Press Enter to reboot immediately.

    Step 18: Now while start up select the GUI mode of setup to continue setup.

    Now you can continue your usual setup process. Follow the onscreen instructions carefully. After the setup process which usually takes 39 minutes, it will restart. Now boot from your Hard drive not the USB drive. Again use BIOS settings to make this happen.
    Congratulations you have successfully installed Windows XP via a USB Drive.
    Important:
    1. You can copy the contents of your pen drive if you want for future use. To use in future just format your USB drive with FAT, run the commands given in Step 5 and simply copy paste the files you had saved earlier. No need to run the whole process again.
    2. While unmounting the Virtual Temp Drive T, it may fail and ask you to try again. Select No. And  when it asks you to Force unmount select yes.
    3. This Method is for informational purpose only and should not be used for Software Piracy and illegal practices.
    4. We are not responsible for any loss or damage resulting from this information.
    5. This method will not work if your motherboard or your BIOS does not support USB booting.
