1.   How can you tell if your computer is safe?

There are a couple of different ways a person can use to tell if their computer is safe. The first way would be to run anti-virus software. There is plenty of anti-virus software that ranges from free to pretty expensive. Another way to notice if something is going on with a computer is if it is acting very slow, unexpected pop-up ads, there are missing files, constant crashes, and other things along these lines. The biggest part of computer safety is the prevention of any bad things happening. The first step to prevent a virus or a hack on your computer is to have an anti-virus program downloaded. After that, all the information needs to be backed up onto a separate space just in case something does happen to the computer. A firewall could also be of big use in security. There are two different firewalls hard and soft to choose from or even both. Another method that can be used to prevent any malware to a computer is constantly changing the password and keeping the password complex and not easy to guess. Encryption is also a very good tool to keep a computer safe. Encryption is a coded message to another person that has the key to decrypt it. Encryption is used in case the email gets intercepted by a hacker but even if it does they can not read it unless they have the key to it. All of these prevention methods put together make it pretty hard for someone to attack your computer. There are many ways to tell if your computer is safe when it is being attacked but the majority of the safety measures need to be taken before a person thinks that their computer has a virus or has been hacked. Prevention of any malware is the best way to keep a computer and information safe.
