What is a computer virus and how do I get rid of it?
A virus is a program that has the ability to copy itself and spread to other computers. A virus can also infect other programs and make them do things that they normally wouldn’t do. For example, a virus might make a program delete files or send out personal information over the Internet without the user’s permission.
Most viruses are created by people who want to cause harm to others, but some are created by mistake. No matter how a virus is created, once it gets on your computer, it can be very difficult to get rid of.
There are two main ways that viruses can spread: through email attachments and by websites that are infected with viruses. It’s important to be careful when opening email attachments, even if they’re from someone you know. And, be careful when clicking on links or visiting websites. If you’re not sure if a website is safe, don’t click on any links or enter any information.
If you think your computer has a virus, there are a few things you can do to try and remove it. First, try running a virus scan with your anti-virus software. If that doesn’t work, you might need to use a special virus removal tool. You can usually find these tools on the website of your anti-virus software company.
If you can’t get rid of the virus, you might have to reinstall your operating system. This will delete all of the files on your computer, so be sure to back up your important files first.
Preventing viruses is the best way to protect your computer. Be careful when opening email attachments and visiting websites. Keep your anti-virus software up-to-date, and run regular virus scans.
