Computer viruses are very common and if you spend a lot of time on the computer, it is important that you know how to protect your computer from them. The first thing you need to do is install an anti-virus package. This will tell you whether or not you actually have a virus. There are free ones you can find online, but they may not be as effective as some of the other ones such as Norton or McAfee.
Set up the software so that you automatically receive updates. It is important that you have the most up to date protection because viruses change all the time. Once your software is installed, you can run a scan on your computer and it will tell you how to get rid of any viruses you may have. Do some research about all the different types of software you can use and choose the best one for your computer.
Be careful of what you download and the sites you go on. There are a lot of things on the Internet that can be harmful to your computer. Also, do not open all of your emails. Only open the ones that are from people you know or other emails you are expecting. If you do not know who the email is from, you will probably not want to open it. Email is probably the most common way people spread viruses. Do research before you download anything and find out if it is safe for your computer.
