OS developers always release security patches that fix the security leaks so as to prevent malware from taking advantage of those leaks to attack users’ computers. If you do not install the patches timely, your computer may be compromised by malware. Typically, you operating system may have been set to look for updates automatically, but it is still suggested that you regularly check whether this function is running properly. This tutorial will show you how to update your operating system.

2. Install quality antivirus software and keep it up-to-date.

Generally, antivirus software is used to secure a computer from being attacked by malware like viruses, worms, and Trojan horses. It also helps detect and remove malware from the infected computers.

Here we need to emphasize the “up-to-date”. Antivirus software can only effectively work, if it is updated to cope with the latest malware circulating on the Internet. Even though you have installed the best antivirus software, your computer may still be attacked by malware, if you do not update it regularly. Most antivirus software has a feature of downloading updates automatically when you are online. If not, it may pop up  message, reminding you to install the updates. Just allow it to update, if you are prompted to do so.

If you cannot afford a paid antivirus product, consider using a free one which is from a reputable and reliable source. Free anti-virus software is better than nothing. But keep in mind that it’s not the best solution. Free antivirus software generally only searches your computer using signature-based detection which involves looking for patterns of data that are known to be related to already-identified malware; while paid antivirus software will include heuristics to catch new, or zero-day threats, by either using genetic signatures to identify new variants of existing virus code or by running the file in a virtual environment (also called a sandbox), and watching what it does to see if it has malicious intent.

3. Enable a firewall when you are online.

Without a firewall, your computer is operating with an “open door” policy and hackers could easily intrude your system and access the data and information stored on your computer. So, it is always a good idea to use a firewall and also ensure that it is running while you are online.

Bonus: Apart from using the built-in firewall, you can also consider downloading and installing other advanced firewalls such as ZoneAlarm.
