1. What is an Antivirus?

An Antivirus is a computer security software that protects a computer from all kinds and variants of malware by continuously monitoring the execution of programs and files, and blocking or removing any malicious programs upon detection using its various technologies. It monitors the internet surfing to scan and protect from harmful websites and phishing attempts. Any incoming from the internet or removable storage devices such as compact discs, or USB flash drives is scanned to block any kind of malware attack on the computer.

2. What is a Malware?

A Malware is an umbrella term that covers all kinds of malicious software, in fact, the term Malware is made from two words Malicious and Software. The various types of malware are:

  1. Virus
  2. Worm
  3. Trojan Horse
  4. Ransomware
  5. Spyware
  6. Rootkit
  7. Keylogger
  8. Logic Bomb
  9. RAT
  10. Adware
  11. Scareware
  12. Rogueware

3. Antivirus vs Antimalware

The most popular term for a computer infection is a Virus, and hence the most logical term for a program that protects against these infections is an Antivirus, but technically this is not the most accurate term. All kinds of computer infections are collectively known as Malware, and hence the program that protects against all types of malware is an Antimalware

4. What are the Various Types of Antivirus Products

  1. Real-time or On-Access Antivirus
  2. Second-Opinion or On-Demand Antivirus
  3. Specialized Antivirus Software

4.1 Real-time or On-Access Antivirus

A real-time antivirus is the actual antivirus that is always working in the background to protect you. The file scanning component monitors every program or file execution, and blocks malware upon detection. The web protection component monitors your internet access and blocks malicious website. A real-time antivirus also scans and protects all of the removable devices that are connected to the computer, and blocks various kinds of malware that propagate through these removable devices. A real-time antivirus is always active, and is automatic in nature. It takes place in real time whenever a program is executed, or a new file enters the system through downloading or from external media such as USB.

4.2 Second-Opinion or On-Demand Antivirus

A second opinion malware scanner is an on-demand file scanner that scans Windows for malware, and then deletes the detected threats. It works differently from a real-time antivirus, which includes an on-access file scanner that works along with various technologies such as signatures, heuristics, behavioural analysis, and cloud to detect and remove threats in real-time. The user selects the programs, files, and folders to be scanned.

4.3 Specialized Antivirus Software

The specialized antivirus software are those software that do the job of protecting your computer by working alongside your main antivirus software. An antivirus covers all kinds of malware but whenever a certain kind of malware spreads and causes extreme disaster, the antivirus companies release dedicated products for that specific type of malware. Right now, Anti-Ransomware is the most premium type of malware for the antivirus companies. Some time ago, dedicated products were being made for Spyware, and Adware.

5. How does an Antivirus Protect Your Computer from Viruses?

An antivirus uses various technologies to protect the user from various types of malware.

Following are the technologies used by Antivirus products to detect malware:

  1. Signatures
  2. Heuristic Analysis
  3. Behavioural Analysis
  4. Cloud Analysis
  5. Sandbox Analysis

5.1 Signatures

The Signature scanning is the oldest and the simplest kind of detection technique. The antivirus companies have a database that contains the signatures (or pieces of code) of all the previously detected malware. This database is known by various names such as Signature Database, Signatures, or Virus Definitions. Antivirus programs continuously scan all of the files and programs on the computer, and then match them with their Signatures. If a file or program matches with a malware available on the database then it is blocked, and the user is notified.

5.2 Heuristic Analysis

The Heuristic scanning is a more advanced form of Signature scanning. Signature-based scanning is the oldest and the most commonly used method of malware identification but it’s not the most reliable one. It cannot protect against threats that haven’t been identified and whose signatures haven’t been created yet. Therefore, the system is vulnerable to such threats. Heuristic Analysis uses algorithms to determine if the program is malicious or not. It examines the code of the program, and tries to find out the outcome of this code using various methods. If the code is similar to the code of a malware already present in the signature database then it blocks the program because it could be a new variant of that malware. This way, it is helpful is catching the new variants of malware. Heuristic analysis is the root cause of false positives, because anti-malware considers a program a malware based on limited information. In reality, that specific program may not be harmful at all.

5.3 Behavioural Analysis

This method is also useful for identifying malicious programs that are yet to receive virus definitions from the manufacturer, or those that have managed to remain hidden until now from the antivirus developers. This method, as the name suggests, analysis the behaviour of the programs. If the behaviour of a program matches that of another malicious program, then the antimalware recognises it as a malware. This method also has a downfall. It is responsible for increased number of False Positives. A legitimate program might be accessing important locations of the system, but the antimalware may block it assuming it to be a malicious program.

5.4 Cloud Analysis

New malware are appearing at an astonishing rate. It’s not possible to create signatures for all of the malware that are found every day. So, in order to provide a more efficient protection to their users, the antivirus companies added another weapon to their arsenal to combat the malware more effectively. In Cloud scanning technology, the malware analysis is done on the cloud i.e., on the antivirus vendor’s servers. The antivirus product installed the user’s computers sends the file related information to the cloud for analysis. Antivirus companies, in fact, advertise this feature, and there are some products that come without signatures. The Cloud analysis along with other detection techniques is used to scan and detect malware in those programs. Cloud has benefits such as virus definitions or signatures are not downloaded on the computer, so no internet and disk space usage. Cloud analysis makes a cloud antivirus lighter than a traditional signature-based antivirus. The drawback of using a cloud antivirus is that it always requires an active internet connection.

5.5 Sandbox Analysis

The Sandbox scanning technology involves running the programs in a virtual environment to check their actions. If a program acts like a malware then it is marked as one. The sandboxing feature can also be used to run those run all of the files that the antivirus can neither whitelist nor blacklist. So, running a file in a sandbox container gives you the best of both the worlds. If the file was malicious then it can’t harm your computer because it was run in a virtual environment or sandbox container, and if it was a legitimate program, then you had the pleasure of running it.

6. Independent Reports

Various independent companies perform different types of tests on different antivirus products to test the protection level provided by them. Then, they publish the results in reports for the users. You can visit their websites to read the latest test results. These reports are made available in the downloadable PDF file format as well.

10. Conclusion

Using the information from all these sources, you can get a fair idea of what is a good antivirus for you. But none of the above-mentioned products or methods is foolproof. They cannot provide a 100% protection. You have to think about the worst-case scenario. Your antivirus may have detected 999 out of a 1000 malware missing only one, and that one eventually strikes you. Malware are designed to bypass these antimalware products, it’s a constant battle. Don’t be dependent on a software to protect your data. There can also be a hardware failure, a physical damage. You can lose your data anytime. Everything about your computer is replaceable expect your data. You can be 100% safe only when you keep regular backups of your data on external storage devices.

So, a word of advice, literally: Backup.
