How to remove a virus is a very hard question. Now and then a virus will be very easy to remove but sometimes you are going to need expert help or even formatting your hard drive and reinstalling the operating system. It’s very hard to remove some and rather than worrying about how to remove the virus I’d suggest you pay a lot more attention to stopping them in the first place.
A virus is a program, a piece of executable code that has the possibility of cloning itself. Computer viruses can spread fast and they are hard to remove. They can be attached to any type of file and they are spread as files are copied and sent from person to person. They can be contacted from a floppy disk or Cd, they can be launched when opening a program or accessing a file, any file, or they can be brought from the internet by downloading a file or accessing a web page and as attachments to e-mails.
Besides replication, viruses also have something else in common and that’s their infecting routine. The behaviors of a virus may vary from showing messages or images to destroying files, formatting the hard disk drive and other severe damage. If the virus does not inflict damage it can still cause problems by taking up space and memory, lowering the performances of the computer.
Nine rules for avoiding a virus:
1. Use an anti virus program at all times.
2. Install and keep active a firewall.
3. Make sure your system is up-to-date with all the virus security updates.
4. Keep your browsers security settings at maximum.
5. Never click yes when your browser asks you if you want to install some program or file coming from a place or person you don’t know trust.
6. Install an anti-spy ware program for greater protection.
7. Never install a browser help or search bar unless it comes from a reliable source.
8. Use a different credit card for online shopping.
9. Don’t click on email attachments that are executable files even if they look as if sent from known persons.
The anti virus programs have a big role in providing your computers security and protecting it from viruses, worms, Trojan horses that can attack a computer. The role of an antivirus program is to detect the presence of viruses in a computer, to disinfect the files or delete the ones that can’t be disinfected and prevent the contamination of the computer. It’s much easier to prevent a virus than it is to remove it.
Most of the companies that produce anti virus software have online free tools for scanning computers for viruses and some will tell you how to remove a virus. If you don’t have an antivirus program yet and can’t decide which one to buy you can enter their online sites and try the services for free, then decide what to use. Just remember, it’s easier to prevent a virus that to remove it.
