If you find a virus in your system and can determine exactly what it is, it is time to remove it from your system. Having put in place procedures to detect viruses is important is a plan for how you remove what you find.
You must remember that the majority of virus alarms prove to be false alarms, and are the result of a user, the software, or hardware error, making the detection of your assumption that, even though it may be a virus, it equally likely to be something Moreover, in order to note that all the symptoms carefully and see what the combination of points.
If the problem can be a virus, it is nonetheless important not to panic. You need a cool head to further damage and to remove the virus as cleanly and efficiently as possible, do not leave your copy of FDISK and FORMAT start or formatting the hard drive.
Using an anti-virus product
Most antivirus products offers virus removal capacity. Typically, these functions are incorporated into the scanner, which gives you the ability to remove a virus in a file when it is detected in the file. Removal of certain viruses is relatively simple for the antivirus products can remove certain viruses, but can not remove very many. When choosing a product, whether the product can remove all common virus removable.
Some viruses can not be removed, whatever clever the author of the anti-virus software. That’s because the virus has broken a part of your original program, which will erase. Without knowledge of what was supposed to be the case, the virus “sitting” a virus can do is propose to abolish the entire program.
Strategy Virus Detection
If the virus is detected in memory, but not in any file, and if the virus detected is extremely rare virus ask whether another scanner that lets in memory scan chain, it can be produced using a false alarm when another scanner works.
If the virus is detected in a single program on your hard drive, ask your self how often you use this program, if you have used on several occasions in the past, then viruses, it had the an opportunity to infect other files, if it has not done so yet, it’s probably a hoax, we should not remove the only program in which the virus has been reported and not attempt removal, However, the restart of a non-write-protected floppy disk and launch a new scanner to determine if she finds something too in this case. If it does not assume that this is a false alarm.
If the virus is detected in several programs that you use frequently, you are almost certainly an infection. Do not attempt to remove the virus produces more! You can do irreparable damage to your files.
To protect computers against viruses
Simply, do not give your e-mail address on a large scale, and never go to a diskette given by someone you do not know. In addition, a charge of antivirus software available, which can detect and clean viruses, but remember, virus programmers are hunted
By the will to stay ahead of this kind of software.
Preventive Maintenance Information Systems
There are three things that can be done to prevent the viral infection in a computer system. These are: -
1) limit the sharing of software
2) insufficient transitivity
3) limit the functionality
It may limit the sharing by limiting the flow of information so as to form a post office all areas of the provision of information in a network system, in such a system, a virus spreads only to those who are in the areas of transit traffic from its original source path.
In a system with unlimited sharing of information limited by the roads, limited transitivity can have an effect if users do not have all the roads, but there is always a direct path between two users, it always l possibilities of infection. For example, in a system with transitivity limited to a distance of 1, it is safe to exchange information with anyone you trust, without having to worry about whether the user wrong to trust another user.
