1. Click on “Start” in the bottom left hand corner of screen

2. Click on “Run”

3. Type in “command” and hit ok

You should now be at an MSDOS prompt screen.

4. Type “ipconfig /release” just like that, and hit “enter”

5. Type “exit” and leave the prompt

6. Right-click on “Network Places” or “My Network Places” on your desktop.

7. Click on “properties”

You should now be on a screen with something titled “Local Area Connection”, or something close to that, and, if you have a network hooked up, all of your other networks.

8. Right click on “Local Area Connection” and click “properties”

9. Double-click on the “Internet Protocol (TCP/IP)” from the list under the “General” tab

10. Click on “Use the following IP address” under the “General” tab

11. Create an IP address (It doesn’t matter what it is. I just type 1 and 2 until i fill the area up).

12. Press “Tab” and it should automatically fill in the “Subnet Mask” section with default numbers.

13. Hit the “Ok” button here

14. Hit the “Ok” button again

You should now be back to the “Local Area Connection” screen.

15. Right-click back on “Local Area Connection” and go to properties again.

16. Go back to the “TCP/IP” settings

17. This time, select “Obtain an IP address automatically”

18. Hit “Ok”

19. Hit “Ok” again

20. You now have a new IP address

With a little practice, you can easily get this process down to 15 seconds.

P.S:

This only changes your dynamic IP address, not your ISP/IP address. If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back

Here are some tips to ensure malware is not given access to your computer:

• Keep your computer up to date.

• Keep your browser up to date.

• Install good antimalware.

• Download free software only from sites you know and trust.

• Avoid clicking links inside pop-up windows.

• If you are offered antimalware programs while browsing, don’t install them. Stick with the software I outline in this handbook.

By following these rules, you’ll protect yourself and decrease the chances of getting malware on your system. The rest of this handbook will show you how to apply the first three tips listed above.

Different Types of Threats to PC

Malware – The generic term used for all forms of software designed with malicious intent. Viruses, worms, spyware etc. are all forms of malware. The term virus is often used when malware should really be used as it describes all forms of malicious software.

Virus – A computer virus acts very much like a human virus. Human viruses are spread, via thumb drives, floppy discs, network connections etc., to other PCs. Viruses need a host (like a free screensaver program) to spread. By pure definition: a virus has the ability to spread itself, via a host, to other computers.

Worm – A worm is much like a virus. The key difference is worms can spread between PCs without a host (free screensaver program, downloaded game etc.) These programsrely on computer networks and usually damage files and slow down networks in their path.

Trojan horse (Trojan) – A Trojan horse is a seemingly harmless program that looks to provide value. However, just as in Greek mythology, a Trojan horse has a secret agenda and acts as a backdoor to your computer. This backdoor can be accessed by a hacker to compromise your PC. Trojan horses are not self-replicating and spread due to users installing them manually on their PC.

Privacy-invasive software – A formal term used to describe software that invades your privacy. This software comes in different forms including spyware and adware.

Spyware – Spyware tracks a user’s activity by monitoring browsing habits and keyboard activity and can even take screenshots while you use your PC. This information is sent back to the creator or beneficiary of the spyware. Signs of spyware include: modified browser homepages, slow internet, and suspicious looking sites in place of legitimate sites (for example: banking sites.)

Adware – Like spyware, adware is software that may track visited websites and act as a key logger. Adware tracks this information to automatically display downloaded or installed adverts to a user. You may wonder why you are being offered “PC Super Anti Spyware 2011” when using your PC; this is adware at work. AIM, FlashGet, Deamon Tools, and RealPlayer are all examples of adware.

Backdoor – A backdoor is a point of access to a computer that does not require authentication. An unlocked house back door gives access to an otherwise secure home; a computer backdoor allows access to your PC without your knowledge or permission.

Key logger – Key loggers are used to monitor keyboard activity on a PC. These can be software-based (bundled with Trojan horses, adware, and spyware) or hardware-based (between the keyboard cable and the PC, acoustic etc.) Usually this information is retrieved across a local network, the internet, or from the physical device connected to the keyboard.

Firewall – A firewall both permits and blocks access to a network or PC. Firewalls are included with popular security software (e.g. AVG Internet Security and ESET Smart Security) and limit communication between your PC and devices that are not authorized to communicate with you.

Windows Firewall – Comes bundled with Windows XP, Vista, and 7. This is a great solution; however, due to a lack of comprehensive definition updates, Windows Firewall is not completely effective in blocking threats and allowing safe connections.

Antimalware / Antivirus / Antispyware – Software designed to remove or block malware (e.g. AVG Internet Security and ESET Smart Security.)

Because of the security features built into Windows XP, it is virtually impossible to get back into the system without the password.

You have several options to try and get around this problem.

If you have access to another user account with administrator rights, you can use that account to change the password

of the account that is locked out. You can also use the default Administrator account that is built into Windows XP.

First you need to boot the system into Safe Mode.

1.Restart your system.

2.When you see the blue Dell globe or screen, press the ( F8 ) key about 3 times a second.

3.You should get the Windows startup menu. Use the (Up or Down) arrow keys to highlight (SafeMode)

4.Press (Enter) on (Safe Mode), then press (Enter) on (Windows XP).

5.The system should boot to Safe Mode.

Once you are at the Account Log on Screen, click on the icon

for the user account with administrator rights, or click on the icon

for the administrators account.

Note: For Home the Administrator account isn’t normally shown & in Safe Mode you have to press Ctrl+Alt+Delete keys twice to show.

For PRO you can do this in normal mode

When the system has booted to the desktop, use the following steps to change the accounts password.

1.Click Start, Control Panel, Administrative Tools.

2.Click Computer Management.

3.Double click Local Users and Groups, double click the folder Users.

4.Right click on the account name that is locked out, and click on Set Password.

5.You may get a warning message about changing the password, simply click proceed.

6.Leave the New Password box blank, also leave the Confirm Password box blank.

7.Click OK, and OK again.

8.Then close all Windows, reboot the system and try to log in.

There are also applications that can recover the password for you.

The following companies provide these applications at a cost.

iOpus® Password Recovery XP here.

Asterisk Password Recovery XP v1.89 here.

If the above information does not help in recovering the password, the only option left is to

format the hard drive then reinstall Windows and the system software.

10 Ways to Speed Torrent Downloads

P2P file sharing is one of the widely used applications now days. The Torrent search engine is the utility which is

excessively used in this context. As the young generation says “impatience is the new world”, means the generation can’t afford anything too slow, same is the case with torrent download. But there are some tips which can really help to improve your download speed. Let’s have a quick glance at these tips.

1. Choose your ISP wisely: The basic rule is that the maximum Torrent download speed that you can get can’t cross the upper limit of the bandwidth

provided by your ISP. Usually ISP’s specify the upload and download maximum for the connections. So it is always better to have an ISP who provides better Download and Upload limits for an affordable price.

2. Choose the right BitTorrent client: Always choose the latest versions among the available BitTorrent clients. mTorrent, Vuze etc are some of these latest versions available now. The latest versions are equipped with provisions for obtaining the highest download speed and an overall smooth downloading experience.

3. Check the seeds and peers:

A peer is a computer which participates in the P2P sharing either for downloading or uploading. A seed is a computer who has got a complete copy of the file and is sharing that file in the network. A leech is a computer who doesn’t have a complete copy of the file, and is downloading the file at the moment. A leech becomes a seed when it completes the download and shares it over the network. It is always advisable to choose the files with more number of seeds and less no of leeches. That means the file with the highest seed to leech ratio.

4. Altering the firewall configuration: By default the firewalls block all the BitTorrent connections coming through. This can adversely affect the downloading speed. So you must make sure that your firewall is configured in such a way that it allows the BitTorrent connections through it. This can be done by checking the box ‘Add Windows Firewall Exception” in the firewall settings following the path

options/preferences/connection. For ease some users may disable the firewall, but it is strongly advised that you shouldn’t disable your firewall that it will open your computer to serious threats.

5. Limiting your upload rate: A peer to peer sharing is all about simultaneous upload and download. So every BitTorrent clients must upload some data at the same they are downloading some other data through torrent. For obtaining a high download speed you should vary your

upload speed accordingly. Usually the upload maximum by the ISP is very much less than the download maximum. It is only 50Kbps for a 2Mbps connection. For fast downloading you can set your uploading speed to 80% of your maximum uploading speed. You must vary the speed as the download progresses for an efficient downloading. Keep the uploading limit maximum in the beginning and then slightly decrease it as the download progresses. In mTorrent the upload limit can be set from the option Global Upload Rate.

6. Selecting a different port: The default port for the BitTorrent file sharing is one between 6881 and 6999. As BitTorrent sharing involves high bandwidth  usage the ISP’s usually throttle traffic on these ports. So you can increase the downloading speed by selecting some port above 10000. Usually mTorrent randomly assign the port as the application starts. So set a specific port with a number above  10000, by disabling the Randomize port checkbox.

7. Increasing the number of Maximum Half Open TCP Connections: Usually the maximum no of half open TCP connections in Windows XP with SP2 is set as 10 for blocking the virus multiplication. But torrent needs more. To facilitate this a patch TCPIP.sys is available. Through this patch you can set the  maximum no of open TCP connections. Set it to any number between 50 and 100.

8. Protocol encryption: Some ISP’s constrict the bandwidth for P2P sharing. Protocol encryption can be used to override this restriction. Check the Allow incoming legacy connections box and make the outgoing Encryption as Disabled for getting maximum speed on Torrent downloads. Between non-encryption is not advisable as it may lead to some encrypted client to be left as undiscovered.

9. Connections and bandwidth: The BitTorrent client you are using will allow you to enter values for Global maximum no of connections: It is the maximum no of connections BitTorrent client can make for any P2P sharing. Setting

this no to a very high value will take up useless bandwidth, and to a very low value will miss out some peers. For a 256kbps connection you can set this number to 130.

Maximum no of connected peers per torrent: Set this no to one which is closer to the no of available peers for the file.

No of upload slots per torrent: It gives the maximum no of peers to which the BitTorrent client uploads at a time. Since a low settings may affect the download set it to a moderate low value.

10. Miscellaneous: Disable the individual files for download along with a particular file, if we don’t want them at the beginning of download.  Be familiar with your BitTorrent client settings from the users manual or web.
