Virus and the way of virus removal process

Virus removal process is not that difficult if you have a good antivirus software. Tis article is to help you to run a virus removal process to scan your computer and e-mail for viruses. This is an essential chore that you’ve got to do on a regular basis in order to ensure that your computer is free of viruses. In many cases, you can configure your antivirus program to automatically perform this scan as often as necessary. Some antivirus programs include this feature; it’s a convenient way to double-check the cleanliness of your inbox

Scan Your Computer File-by-File

Antivirus programs use two main methods to detect viruses on the way of virus removal process :

Automatic protection: Antivirus programs can (and do) carefully watch all of your computer’s hard drive activity while you’re doing whatever you do on your computer and start virus remova process. If your computer is about to copy a file containing a virus to the hard drive (or floppy, or CD-ROM), the antivirus program will detect this and immediately intervene to block the action.

Scanning: A scan is different from real-time protection. A scan is a one-time file-by-file examination of virus removal process of your entire computer — sort of a house-by-house search — looking for viruses that may be hiding inside of a program or document. You can also do a scan of removable media such as floppy disks and CD-ROMs before you use them. The automatic real-time method fo virus removal process isn’t 100-percent reliable. It is not implying that there is something wrong with antivirus programs. But there are some ways that viruses can circumvent your virus removal process.

If you scan your entire computer say, every week, on the other hand, then by the time your next weekly scan occurs, chances are that your antivirus program will have downloaded a new virus definition that includes a signature for the new virus. The weekly scan will then detect the virus that the automatic detector missed. Your antivirus program actually can be circumvented in two ways:

New or unknown viruses: Your antivirus program can only stop viruses that it knows about. If a brand-new virus pops up on the Internet, it’s possible that it will get to your computer before your antivirus company can get a virus definition file with the new virus’s signature into your computer. If your computer gets one of these brand-new viruses, it could also be spreading the virus to other computers without your knowing it.

Computer malfunctions: A computer malfunction can also make it vulnerable to viruses. For instance, perhaps your antivirus program had some kind of a strange problem that caused it to stop watching for viruses in its “real-time” module. The antivirus program might get sick on its own accord, or a malfunction elsewhere in the computer’s hardware or software might cause it to freak out and stop working.A user malfunction can invite troubles, too. One thing I’ve seen a few times is a situation where the installation procedure for a new program asks you to temporarily disable your automatic virus protection to prevent it from interfering with the installation. If you forget to reactivate your antivirus program’s automatic protection, then any virus — new and old — can walk right in if it gets the chance.

Scanning the entire computer

Let your antivirus ptogram to look at the entire hard drive and every file in it to start a virus removal process. It’s actually pretty easy to tell your antivirus software to do this — just scan drive C:, or all hard drives, or however your antivirus program offers the choices to you. There are probably ten thousand or more files on your computer, and probably many times more than that. Your antivirus software is meticulous and actually enjoys examining every blade of grass in the field. Not much else to do, I guess. To scan your entire computer for viruses, follow these steps:
1. Open your antivirus program and run the Scan command. Each program is a bit different, but the Scan command is usually a button or hyperlink toward the top of the main interface screen.
2. Select the drive letter that corresponds to your computer’s hard drive.

Scanning your entire hard drive could take an hour or longer. This depends upon many factors, including:

### The speed of your computer’s processor
### The size of your hard drive
### The speed of your hard drive
### The number of files on your hard drive
### The extent of fragmentation on your hard drive
### Your patience
So it’s hard to say how long it should take, but here’s why it takes so long.

There are over 60,000 known viruses today, and your antivirus program has “signatures” on each one of them in your computer’s virus definition file. When your antivirus program scans for viruses, it opens each of the overten- thousand files on your computer, and examines each one for the presence of all of these viruses.

Most programs give you a choice of which drive letter to scan. If your computer’s hard drive is divided into two or more drive letters, you’ll need to scan each one. And likewise, if your computer has more than one hard drive, then you’ll need to scan each one. It’s possible, though, that your antivirus program has an All Hard Drives option, which makes this easier.

How often to scan

You need to periodically scan your entire computer for viruses if you want to be completely sure that your computer is virus-free. For a number of reasons, your antivirus program’s real-time virus protection is not infallible. But how often is often enough to run a virus removal process? If I were forced to give a general answer to fit most users’ purposes, I would have to say that scanning your entire computer for viruses once in 2 weeks is about right. Some of you, though, should scan more frequently; it depends on what you do with your computer. For instance, if you make your living on your computer by day-trading stocks, business on eBay, or using for office work everyday , then you have a lot more to lose than if you do a little e-mail and surf the Net now and then. So the economic value of your computer may prompt you to scan more often for viruses. If you are engaged in doing a lot of downloads or file sharing or you have a habit of opening the attachments in e-mail messages from people you don’t know, then you are increasing your risk of catching a virus. If you fall into this high-risk group, then you’ve got to scan your computer more often to be sure that your computer is virus-free.
