got a large number of folders you want to share on the network?

If you’ve got a large number of folders you want to share on the network, navigating to

each one of them and going into their properties and changing them one by one can be

quite a nuisance. Even sharing can be as simple as “Next, next, and next” with the

Shared Folder Wizard (Start > Run > “shrpubw” > [Enter]).

You can even set share permissions right there, so there’s no need to go back to those

shared folders for additional settings. Just remember to check the “Run this wizard

again” box at the last dialog if you want to move on to the next folder.

A worm is a program that spreads over a network. Unlike a virus, a worm does not need to attach itself to a host program for propagation. Some worms use email to spread, sending themselves out as an attachment to other users. Some of them exploit the vulnerabilities in software running on a victim’s machine, aiming to take control of those systems. Some worms also spread by using cross-site scripting vulnerabilities in web servers or services.

A Trojan or Trojan horse is a software application that pretends to provide legitimate functionality, but actually carries out malicious functions, exploiting the legitimate authority of the person who starts up the program. It can be used as an attack tool to capture sensitive information such as user accounts and passwords. Unlike a virus, a Trojan does not replicate itself. It spreads usually by enticing the user to install software such as “shareware” which is embedded with a Trojan horse.

Spyware is a type of software that secretly forwards information about a user's online activities to third parties without the user's knowledge or permission. The information is mainly used for purposes related to advertising. For example, sending spam emails to the user in order to deliver targeted advertisements by marketers. Some spyware might also be able to steal a victim’s files or even keystrokes to gain sensitive and personal information.

Adware is a type of software that displays advertising banners while a program is running. Most adware is also spyware. In many cases, freeware developers offer their products free-of-charge to users, receiving financial support from adware marketers by bundling adware into freeware products.
You should carefully read the terms of use before installing any freeware or shareware. The use of freeware and shareware may sometimes imply that you agreed to install adware systems as well.

Backdoor is a general term for a malicious program that listens for commands on a certain network port. Most backdoors consist of a client component and a server component. The client component resides on the attacker's remote computer, and the server part resides on the infected system. When a connection between client and server is established, the remote attacker has a degree of control over the infected computer. For example, a backdoor may allow a attacker to monitor or take control of an infected computer, stealing data from it, uploading and activating viruses, or erasing user data and so on.

HOW TO OPEN BLOCKED WEBSITES

IF you are not able to visit your favorite websites in your school or college or any place where some sites are blocked?

Microsoft recently released Windows 7, the best Windows Operating System so far. Since Windows 7 comes with a number of interface and functionality changes, you are bound to face some problems in the beginning, like,

Today we are going to see how to do that.
First you need to install Google Gears, you can download the online installer from here
http://gears.google.com/
Run the online installer and it will install Google Gears on your system.

1) All you need is your friend's IP Address and your Command Prompt.
2) Open Notepad and write this code as it is.....!

First of all copy a icon file to the root of the drive.
example: c:\icon.ico

Now a days we can use pen drive itself as a RAM for our system and just increase the general boot up speed and also operational speed of the system . Now a question arises that "Is it possible only for those who have Vista OS " ? my answer is a Big NOOOO..

These are some really cool tricks to try in windows xp.

Why is it that Anti-Virus software cannot repair files that are infected by a Trojan or a worm?

Strictly speaking, there is no such thing as “file infected by a Trojan or a worm”. One difference between a virus and a Trojan or a worm is that a virus will replicate itself to a clean file, which will in turn infect other clean files when the infected file is executed or opened.
A Trojan is a malicious program installed on an infected computer which does not attach itself to any file. Worms are also malicious software that spread across networks but do not replicate onto a clean file. Therefore, there is no file to repair when it comes to a Trojan or a worm.

How can I protect my PC against viruses and malicious code?

Always install and enable anti-virus software or malicious code detection and repair tools. You can also consider similar products that work against spyware and adware. You should enable and configure the live update feature of your virus signature and malicious code definition files, if available, setting the frequency to update daily. If automatic update is not possible, manual updates should be conducted at least once a week.

You should reject and delete such virus-infected emails and never open any attachment in such messages. You should also ensure that you have adequate virus protection measures in place on your computers, and that anti-virus software is kept up to date with the latest virus signatures and detection and repair engines. Unless it is possible to verify the apparent sender address of the virus-infected email, do not send any enquiry message to the apparent sender because in most of the cases, the sender address is spoofed and the sender whose email address it is has nothing to do with the virus-infected message. This avoids further confusion and unnecessary allegations.

How can I prevent my PC from becoming a zombie?

The following best practices can help protect your computer from being taken over as a zombie:

Windows XP is configured out of the box to routinely scan for and download updates to Windows XP automatically. While this can be somewhat convenient for those with very fast Internet connections and those who would otherwise forget to check for updates, it can be a nuisance for the rest of us, who are still using 56k or, even worse 33k modem connections.

If you like to increase/optimize your Hard Disk I/O - read/write speed without buying expensive software utilities to do that job or changing the HD, just follow next steps. With doing these steps you will increase Hard disk speed (depends of manufacture and specification, but its worth to try). The most speed improvement is visible with IDE drives; however there are reports that this tweak also does good for SCSI disks.

Open Unknown File Types

“I have a strange icon on my desktop. How do I open the file I just downloaded?” I am sure you heard something similar to this at least a few times, or maybe you asked yourselves about opening some file with a strange extension. Of course, you can easily use Google to search for details about the tools needed to open .ISO or .7Z files, for example, but why not have a program do that for you, and then some?
Most power users will laugh at this, but no matter how trivial may seem to be, using the OpenWith.org desktop tool can help you save a lot of your precious time, and since this is the most important asset one has, right after health and freedom… I didn’t pick this subject just to post another article here! When you need to open unknown file types, everything gets much easier if the research part is already done, there’s no need to argue about that.

Recover Windows Passwords

If you are stranded in a situation where you either don’t remember the password to your Windows account or are trying to help a Windows user by logging to a machine whose user has forgotten the password, this post will be of help to you.

There are a lot of Password Cracking Utilities available, and to this, I will use Ophcrack.

Ophcrack is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms.

Follow the steps below to recover Windows user id and password information

1.) Point your browser to http://ophcrack.sourceforge.net/ and download ophcrack live cd image for your OS depending on whether you run Windows XP or Vista.

Download ophcrack live-cd for Windows XP or Windows Vista

2.) Once you have downloaded the image, you can write this image into a cd or dvd for use.

3.) Insert the DVD with the live cd image and reboot your computer. Ensure that you make CD Drive as the primary boot device. The computer should now boot using the Live CD you burnt on the DVD earlier.

4.) Select the first mode which says ” ophcrack graphic mode” and hit Enter.

5.) Upon hitting enter, the software will take you to a user interface and will begin scanning for the userid’s and passwords.

ophcrack gives you the list of userid and password combinations after completing the scan.

6.) Once you have the userid and password, you can remove the CD and login again to the Windows terminal using the userid and password obtained.
