Computer Security Software

Computer security software keeps your computer protected and your personal information safe.

As soon as you connect your computer to the Internet, it starts getting attacked by the cyber criminals. They use automated software that scans and attacks any computer connected to the network.

Computer security software protects your computer in real time by detecting and stopping the malicious software from damaging it.

It updates itself automatically with new software versions, and notifies you when there is a security problem with your computer.

Computer security software tools include:

You should also have a good backup of your data, because even with the best computer security software tools installed, nothing is unbreakable.

Software Protection Layers

To protect your computer and personal data, you need more than one type of computer security software. Each type of software does a good job performing certain functions: catching viruses, catching malware, managing your passwords, securely erasing your data, and backing it up.

Some security software can performs multiple functions. But such programs are not necessarily good at everything. The best computer security software strategy is to use a combination of tools, where each tool does its primary job well.

Anti-virus Software

Antivirus software protects your computer from viruses. Viruses are malicious programs that attack your computer, usually to steal data, hold your data hostage (you have to pay a ransom to get your data back), or damage your computer.

Your computer can get infected when you visit a malicious website or click on an email attachment that contains a virus. Having a high quality anti-virus product - supplied by a reputable security company - that does real-time virus detection is important.

Anti-malware Software

Anti-malware software protect your computer from malware. Like viruses, malware are malicious programs that attack your computer. Spyware, Trojans, ransomware and website tracking cookies are examples of malware.

Like with viruses, you can get infected by visiting a bad website, opening a malicious email attachment, or using a USB flash disk that has been infected.

Password Managers

Passwords are gateways to our personal information. Having excellent, hard-to-guess passwords - and a different password for each online web service or account - is extremely important. But remembering tens or hundreds of good passwords is not possible.

You are now faced with a choice: do I use easy-to-remember and not very secure passwords that I use for multiple online services? Or do I use excellent, hard-to-guess passwords that I write down in my notebook or on a sticky note?

No one should have to face this choice. With a password manager program you can keep great, hard-to-guess passwords - as many of them as you need - in one central secure location.

File Shredding Software

When you delete a file or document from your computer, it does not get completely deleted. File recovery tools - which are readily available, and used when you delete files by mistake and need them back - can recover deleted documents and files.

To completely delete a file, it has to be overwritten many times with meaningless bits of information. File shredding utilities do this. After a file is shredded, it is much more difficult - and likely impossible - to recover.


Backing up your personal files and data is a critical component of the layered approach to computer security. Your mindset should be that you will lose your data at some point. The only way to recover from data loss is to have good backups.

One way to back up your data is to an external USB drive. This way if your computer gets broken into, or has a hardware problem, you have a copy of your data on the USB disk.

You could also make another copy of your data to a second USB disk, and give it to your friend. It may be a good idea to encrypt the USB disk, just in case.

There are also cloud backup solutions that make it easy to back up your data to an off-site (remote) location. Because cloud backups are automated, and you don’t have to copy any data yourself like you do when using an external USB disk, it is a recommended solution.

Computer Security Software Summary

There is no single best computer security software. The best way to protect your computer is to use a combination of security tools, where each tool does a specific job well.

This is similar to running a basketball team. You can’t win with just one player, no matter how good he or she is. And you can’t win with five point guards or five centers.

To compete, you need a combination of players, each with a different set of skills, all working together toward a common goal.

You’re the coach. Sign up a few good players (get a few security software tools), manage them well (configure them correctly), and you will do just fine.
