How to Remove a Virus Using Command Prompt

How to Remove a Virus Using Command Prompt

 Virus is a computer program that can copy itself and infect your computer. These viruses can spread via USB/flash drive or from one computer to other computer by few written codes. There are many antivirus software available to remove viruses from computer. But there are some viruses or suspicious files which can’t be removed by any antivirus software. Some suspicious files such as autorun.inf initiate all the viruses in pc. These files must be removed for safe operation of your pc, because they may lead to data loss, software damages etc. Such viruses and files can be removed by using cmd. In this article we will discuss how to remove a virus using command prompt. Following steps can be used to remove a virus using command prompt from your computer.

  •    Go to start menu and type “cmd” in the search box or Start>all programs>accessories>command prompt.
  • Open the infected drive such as write , g: to go to G drive.
  • Now type dir/w/a . It will show all the files of the drive including hidden files.
  • Locate AUTORUN.INF or any Virus and other suspicious files in the directory.
there was no virus in my drive so only autorun.inf is been highlighted.
  • Type command attrib  -r –a –s –h to remove attributes of corresponding file.
Type del autorun.inf to delete autorun.inf file.

  • Now type del virus name.exe t delete it, eg : del newfolder.exe .
(You can also delete viruses by using following steps:
  • When you find an Autorun.inf file or any other unusual .exe file just rename it.



Syntax for rename is (rename filename.extension new name ,  for example: (rename autorun.inf virus) to rename autorun.inf file. Here I have renamed it by “virus”.
  • Now you can access the defected drive without affecting the virus.
  • To delete the renamed file go to the defected drive and select the file you renamed.




Now delete the harmful renamed files.)
You have deleted that virus successfully but sometimes virus resides in the Recycler folder.To locate this folder:
  • Type cd recycler command.
  • Again type dir/w/a  to locate all file of the folder.
  • Identify malicious files and delete them using above commands.
Follow the above steps carefully and i think this information is enough to remove a virus using command prompt easily.
Important: Make sure that no other processes being running while performing these actions. Best of luck.

Understanding Bandwidth Part-1

BandWidth:Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.

Network Connectivity:The internet, in the most simplest of terms, is a group of millions of computers connected by networks. These connections within the internet can be large or small depending upon the cabling and equipment that is used at a particular internet location. It is the size of each network connection that determines how much bandwidth is available. For example, if you use a DSL connection to connect to the internet, you have 1.54 Mega bits (Mb) of bandwidth. Bandwidth therefore is measured in bits (a single 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between your computer and the internet.

If you have a DSL connection to the internet, you have dedicated bandwidth between your computer and your internet provider. But your internet provider may have thousands of DSL connections to their location. All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accommodate your needs and up to 166 other users (255/1.54).


Traffic:A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway and traffic is the number of cars on the highway. If you are the only car on a highway, you can travel very quickly. If you are stuck in the middle of rush hour, you may travel very slowly since all of the lanes are being used up.

Traffic is simply the number of bits that are transferred on network connections. It is easiest to understand traffic using examples. One Gigabyte is 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes. To put this in perspective, it takes one byte to store one character. Imagine 100 file cabinets in a building, each of these cabinets holds 1000 folders. Each folder has 100 papers. Each paper contains 100 characters - A GB is all the characters in the building. An MP3 song is about 4MB, the same song in wav format is about 40MB, a full length movie can be 800MB to 1000MB (1000MB = 1GB).

If you were to transfer this MP3 song from a web site to your computer, you would create 4MB of traffic between the web site you are downloading from and your computer. Depending upon the network connection between the web site and the internet, the transfer may occur very quickly, or it could take time if other people are also downloading files at the same time. If, for example, the web site you download from has a 10MB connection to the internet, and you are the only person accessing that web site to download your MP3, your 4MB file will be the only traffic on that web site. However, if three people are all downloading that same MP at the same time, 12MB (3 x 4MB) of traffic has been created. Because in this example, the host only has 10MB of bandwidth, someone will have to wait. The network equipment at the hosting company will cycle through each person downloading the file and transfer a small portion at a time so each person's file transfer can take place, but the transfer for everyone downloading the file will be slower. If 100 people all came to the site and downloaded the MP3 at the same time, the transfers would be extremely slow. If the host wanted to decrease the time it took to download files simultaneously, it could increase the bandwidth of their internet connection (at a cost due to upgrading equipment).


Hosting Bandwidth:In the example above, we discussed traffic in terms of downloading an MP3 file. However, each time you visit a web site, you are creating traffic, because in order to view that web page on your computer, the web page is first downloaded to your computer (between the web site and you) which is then displayed using your browser software (Internet Explorer, Netscape, etc.) . The page itself is simply a file that creates traffic just like the MP3 file in the example above (however, a web page is usually much smaller than a music file).

A web page may be very small or large depending upon the amount of text and the number and quality of images integrated within the web page. For example, the home page for CNN.com is about 200KB (200 Kilobytes = 200,000 bytes = 1,600,000 bits). This is typically large for a web page. In comparison, Yahoo's home page is about 70KB.

How Much Bandwidth Is Enough:It depends (don't you hate that answer). But in truth, it does. Since bandwidth is a significant determinant of hosting plan prices, you should take time to determine just how much is right for you. Almost all hosting plans have bandwidth requirements measured in months, so you need to estimate the amount of bandwidth that will be required by your site on a monthly basis.If you do not intend to provide file download capability from your site, the formula for calculating bandwidth is fairly straightforward:

Average Daily Visitors x Average Page Views x Average Page Size x 31 x Fudge Factor

If you intend to allow people to download files from your site, your bandwidth calculation should be:

[(Average Daily Visitors x Average Page Views x Average Page Size) +
(Average Daily File Downloads x Average File Size)] x 31 x Fudge Factor

Let us examine each item in the formula:

Average Daily Visitors:- The number of people you expect to visit your site, on average, each day. Depending upon how you market your site, this number could be from 1 to 1,000,000.

Average Page Views:- On average, the number of web pages you expect a person to view. If you have 50 web pages in your web site, an average person may only view 5 of those pages each time they visit.

Average Page Size:- The average size of your web pages, in Kilobytes (KB). If you have already designed your site, you can calculate this directly.

Average Daily File Downloads:- The number of downloads you expect to occur on your site. This is a function of the numbers of visitors and how many times a visitor downloads a file, on average, each day.

Average File Size:- Average file size of files that are downloadable from your site. Similar to your web pages, if you already know which files can be downloaded, you can calculate this directly.

Fudge Factor:- A number greater than 1. Using 1.5 would be safe, which assumes that your estimate is off by 50%. However, if you were very unsure, you could use 2 or 3 to ensure that your bandwidth requirements are more than met.

Usually, hosting plans offer bandwidth in terms of Gigabytes (GB) per month. This is why our formula takes daily averages and multiplies them by 31.

Summary:Most personal or small business sites will not need more than 1GB of bandwidth per month. If you have a web site that is composed of static web pages and you expect little traffic to your site on a daily basis, go with a low bandwidth plan. If you go over the amount of bandwidth allocated in your plan, your hosting company could charge you over usage fees, so if you think the traffic to your site will be significant, you may want to go through the calculations above to estimate the amount of bandwidth required in a hosting plan.
 
 
                      

Important Mobile Tips for you

Important Mobile Tips for you
1.)Emergency number:The Emergency Number worldwide for Mobile is 112.If you find yourself out of coverage area of your mobile network andthere is an emergency, dial 112 and the mobile will search any existing network to establish the emergency number for you, and interestingly ,this number 112 can be dialed even while the keypad is locked.

Try it out.

2) Locked the keys in the car? Your car has remote keys?:This may come in handy someday. Good reason to own a cell phone: If you happen to lock your keys in the car and the spare keys are home, call someone on your cell phone. Hold your cell phone about a foot from your car door and have the other person at your home press the unlock button, holding it near the phone on their end. Your car will unlock. Saves someone from having to drive your keys to you. Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other "remote" for your car, you can unlock the doors (or the trunk).

3) Hidden Battery power:Imagine your cell battery is very low, u r expecting an important call and u don't have a charger. Nokia instrument comes with a reserve battery. To activate, press the keys *3370# Your cell will restart with this reserve and the instrument will show a 50% increase in battery. This reserve will get charged when u charge your cell next time.


4.)Your MOBILE is original or not:Type on main screen

*#06#

as we know it will show us; IMEI number (International Mobile Equipment Identity), but through this number we can find out from where it was made.

Look at closely to number Seven and Eight if these are;

02 or 20 that mean it was Assembled in Emirates.
08 or 80 that mean it was Assembled in Germany.
01 or 10 that mean it was Assembled in Finland.
00 that mean it was Assembled in France.

Increase your RAM speed

Increase your RAM speed
1). Start any application, say Word. Open some large documents.

2). Press CTRL+SHIFT+ESC to open Windows Task Manager and click Processes tab and sort the list in descending order on Mem Usage. You will notice that WINWORD.EXE will be somewhere at the top, using multiple MBs of memory.

3). Now switch to Word and simply minimize it. (Don't use the Minimize All Windows option of the task bar).

4). Now go back to the Windows Task Manager and see where WINWORD.EXE is listed. Most probably you will not find it at the top. You will typically have to scroll to the bottom of the list to find Word. Now check out the amount of RAM it is using. Surprised? The memory utilization has reduced by a huge amount.

5). Minimize each application that you are currently not working on by clicking on the Minimize button & you can increase the amount of available RAM by a substantial margin. Depending upon the number and type of applications you use together, the difference can be as much as 50 percent of extra RAM.

In any multitasking system, minimizing an application means that it won't be utilized by the user right now. Therefore, the OS automatically makes the application use virtual memory & keeps bare minimum amounts of the code in physical RAM.

Airtel Broadband Hack : Increase Your Internet Speed


Requirements :
1) An Airtel broadband connection.
2) Any Airtel phone number with high broadband speed : Yes, you need a phone number of Airtel with high broadband speed like 256 kbps. Airtel connection is so common that any of your friend or neighbour might be using it. Just ask for their phone number and save it. As an example, I am assuming a number1234567

Step1) Now comes the tricky part : Just call 197 from your Airtel landline phone and ask for the following details of the number 1234567.

>> Name of the owner of this number.
>> Address of the owner of this number.

Step 2) That's it. Now note down the 2 details mentioned above.

Step 3) Now call customer care ( 4444121) from Airtel landline and tell them that I need the Account Number and give them the phone number you have e.x 1234567

He/she will ask you for the account details and tell them exactly what you noted in Step 2.

Note : Airtel by default sets the username as Phone Number and password as Account Number.
Now you have phone number and account number of a person that has a high broadband Airtel connection.

Now I am going to tell you that what to do with the phone number and account number.

Step 4) Open Internet Explorer or Mozilla Firefox and in the address bar enter the following address and hit enter.

192.168.1.1


When you will press enter a Window will pop up asking for User Name and Password.

Step 5) In the user name and password field enter the details below :

User Name : admin
Password : password


DSL Router will open and we have to make some changes in the Modem settings.

Step 6) In the left sidebar click on WAN and a new page will open and click on EDIT.

Have a look :





Click on Edit and keep on clicking Next until you get this screen :



Now in the PPP Username and PPP Password enter the following :

PPP Username : 01721234567@_dsl@airtelbroadband.in ( Here is 0172 is my State Code and 1234567 is the phone number is assumed but in your case both will be different. )
PPP Password : enter the account number that your noted in Step 2

After entering these keep on clicking Next and at last click on Save and then Save and Reboot.

Now reboot your system and check your Internet speed here.

Congrats now you have high Internet Speed connection.

how-to-hack-into-broadband-adsl-modem-router-and-get-the-broadband-user-id-and-password


First connect to your broadband, and goto http://whatismyip.com to know your public IP Address.


Now you need Port Scanner software, here I used a free one from RadMIN. Open Port Scanner after install and type your IP Range like following figure and set port range from 80 to 81.
Hit Scan button as soon as you finish above steps.
After finish scanning you have to look for the alive IP Addresses those have port 80 opened like following figure.
Here I have found IP Address with port 80 opened. No you have to open that IP Address from internet Explorer like following figure.
If everything went fine, It will ask you for user id and password, and out of 10 ADSL Router, at least 6 having default password, coz no one bother to change that default password L .
So, give it a try with following ID and Pass:
ID : admin / Pass : admin (most common)
ID : admin / Pass : admin123
ID : admin / Pass : admin321
ID : root / Pass : root
ID : root / Pass : admin
ID : admin / Pass : root
ETC…
Wow!! I have got the access… Now I can do whatever I want. But I don't want to do anything:)
You can access any settings on the ADSL Router.
Now you need an Asterisk Key recovery tool to get the broadband user ID and Password:)
Here password recovered successfully in a second. :)
NOW, the question is how you are going to protect your own ADSL Router?
Simple!! You have to check few things, add some extra security to avoid such incident in future.
CHECKLIST!
  • After Installation of your modem, ask the engineer about your modem user id and password.
  • 90% of ADSL Modem using http://192.168.1.1 for their own console, so logon to that console and change your modem console password immediately.
  • If you are using your modem to connect internet for only one system, it's recommended to configure modem as BRIDGE type, coz, here you have to dial from your own desktop, so, it's not required to save your broadband user id and password in your modem.
  • In some router, you can restrict console access, if it is supported by your router, and then enable it for Private Network only.
  • Finally, if you are reading this topic, then after reading, tell your friends about this hole, and secure yourself as well as your friends:)
