There are different methods through viruses may be transferred from one computer to another.

• Now- a-days, most of the viruses spread due to receiving unknown e-mail messages that contains viruses. When a user opens such an infected message, the virus is also loaded into the computer memory. In this way, many other program files loaded into the memory are infected. This virus is also transferred to other computers when e-mail messages are sent from the infected computer to them. Due to these viruses, some time an auto generated email message from your email ID sends to your friends from your side with different virus messages. Never open unknown and attractive subject line email messages, always scan first even if you know the sender of the message. 


• Another way of spreading virus is by using Internet and other networks. For example, when you download infected executables files or data files from the Internet or from a shared disk on the network, viruses are transferred to your computer. It must be noted that many software are available on the Internet with free of cost. Most of that software contains viruses, for example free PHP or ASP scripts are the main source of virus, always get these scripts from reliable sources. In an LAN, if a computer contains a virus, then all the computers on the network may be infected with that virus.  


• One important means of exchanging data is through the use of removable media like, CDs, MP3 player, ipod and flash devices. So, when you copy the data from one computer to another by using a removable media, the viruses are also transferred. 


• The virus can also infect your computer by using pirated software. The software, which is installed into your computer without license is referred to as pirated software. Some companies may intentionally attach some virus programs into their software. This program will only activate when it does not find some special files like license files on your computer.

Change AutoRecover interval in Office 2007 and 2010

Among the many useful features of the Microsoft Office 2007 applications is AutoRecover.  It involves saving all the data in the Office 2007 application after a specific time interval so that it is recovered in case there is a power outage or a system crash. All your work or data in the Office application is saved automatically after that specific time interval. This feature keeps you from losing work you have done. By default, this AutoRecover interval is set to 10 minutes in all the Office 2007 applications. However, it is possible to change AutoRecover interval in Office 2007.  If you change AutoRecover interval in Office 2007 to less than 10 minutes such as after every 5 minutes, you will be able to save your work or data frequently. It will prove very helpful if you are facing problems in the power supply or your operating system.

The option to change AutoRecover interval in Office 2007is offered for every application. Here we will use the example of Excel 2007. Follow these steps to change AutoRecover interval in Office 2007:

1.     Click on the Office button.

2.     Click on the "Excel Options"  button on  the bottom of the resulting menu

.3.     The Excel Options dialog box will appear. Select Save on the left hand side of the menu

.4.      Check the box for "Save AutoRecover information"     .5.  Select how often you would like Excel to save the data for AutoRecover. 

 

6.     Click OK.

 

You should not set the time to a very short time interval. Remember that when working on larger worksheets or documents don't set the AutoRecover to a very short time interval such as 1 minute because that may begin to slow down the computer, as saving a large amount of data after each minute will strain the computer.

 

Graphic Card Troubleshooting

The graphic card is one of the most important pieces of hardware in your PC. Without it, your super monitor with all the bells and whistles is just a junk box.

Make Directional Input

Most video cards come with simple frame capture programs, but you'll have to do some programming if you plan to integrate video capture with other operations on your computer, such as adding text data as an overlay or changing video-in channels on the fly. In this case you'll need good programming libraries in a language with which you are familiar for the video card. Some companies include libraries with their cards, but most charge extra. Most often libraries, when available, are for C or BASIC, and sometimes Pascal.

Choose Between 24 bit and 32 bit

For True Color mode, some graphic cards offer 24 bit while some offer 32 bit. Which is the best? When True Colour mode was first suggested, it utilizes 32 bit which was very pleasing to the eye, they realize that 24 (with less coolers) won't look much different since the human eye can only take about a certain amount of colors. On the other hand, 24 bit will run faster compared to 32 bit because it uses less colors. So if your card utilizes 24 bit, don't worry, it isn't bad.

Always Use The Latest Drivers

Yes, it is important to make sure you always have the latest drivers. The latest drivers will offer you better performance, more utilities and more compatibility (usually for DirectX or Direct3D). Take the effort to check you card manufacturer's site to look for the latest driver updates.
