There are several things that must be taken to ensure that the use of computers at home (home computing) can be run safely and comfortably. 
Three Easy Steps
As a computer user at home, in accessing the Internet through a broadband connection or traditional dial-up use, you should do at least the three following basic security measures to protect the comfort of your home computing process:
1. Antivirus Software installation and maintenance

2. Update Antivirus
Nearly every day found a new virus. At least once a week you should check the web site vendor that makes anti-virus software to determine whether there is an update available.
3. Do not Open File Unknown or Email
Many viruses and worms are called "social engineering". The point is that these viruses or worms to manipulate you in the process of spreading. Latest virus can appear disguised as an email terkirimdari address, so that it looks like delivered by a person, not by a computer that menginfeksinya. If there was an email from someone you do not know, the easiest way is to immediately delete it without looking. If the email appears to be from someone you know, you should read it carefully before opening any attached files. Viruses and worms often have bad English and grammar. Consider whether the person who you know would write a message or send the attached file. If in doubt, contact the person who you know to confirm they actually sent it before opening the attachment.
Make sure your computer is protected from harmful things. As new viruses are discovered, new vulnerabilities are found. Many of them are in the operating system, like Windows.

Staying up to date can be difficult. Some software vendors, like Microsoft, have automated utilities that detects whether there is any updates and notify you of other vendors who have a mailing list where you can join and they will notify you of any new updates. If your vendor does not offer one of these solutions, we encourage you to frequently visit the support web site regularly to see if any new patches or updates.
