Hackers can be avoided by taking necessary measures like having up-to-date antivirus software, strong passwords and a good firewall. There are other ways to avoid hackers as well, like avoiding phishing scams.
There is antivirus software available for purchase that can protect a computer from attacks by hackers. While this software can be costly, they cost much less than the price of having to pay a computer repair bill or having to lose files from a system restore. These software also regularly update themselves once installed, which makes them very effective. There are also applications and browser add-ons designed to encrypt emails, check site authentication and use multi-step password verification.
There are other ways to get rid of hackers, however. It is important to have very strong passwords. A strong password should have more than eight characters, include a random combination of uppercase and lowercase letters, as well as symbols and numbers. This makes it very difficult for hackers to guess passwords. If one has to make up a security question, make sure that it is not a question with an answer that can be found through the Internet, like where one went to high school or one's own middle name. Furthermore, it's important to keep the computer's firewall on at all times. This prevents many hackers from compromising a computer. Suspicious emails should also be avoided, as these could be scams designed to steal one's personal information.
