You may have been under the impression that the internet is a secure place, but in reality, it is not so unless you choose to make it secure. Your work or your curiosity may require you to browse a lot of websites without realizing that some of them may be phishing websites or that you may have downloaded some malicious files. When you do so, your PC acquires hazardous computer viruses that pose a threat to the safety of both your device and your personal information. Nevertheless, many internet guides still claim they can show users how to run a PC safely without an antivirus. But it is not a feasible idea in the long run.
Primary protection for your PC
Malicious software is capable of completely damaging your PC, compromising basic security, and erasing important documents. While some computer viruses are acquired through popup messages and free programs, they can also be distributed through spam emails. Besides, when you insert removable media devices such as USBs, DVDs, and CDs, your PC runs the chance of getting infected with viruses, causing software vulnerabilities. So, it all boils down to one thing: having good antivirus software is the ultimate solution for detecting and removing computer viruses before they can harm your system.
Before moving on to understanding the importance of protecting your PC with antivirus software, you must become familiar with the different types of malicious software and how they can corrupt your system.
- Spyware: Spyware is a type of malware that steals the user’s personal information like contact details, address, bank details, passwords, and much more.
- Viruses: Computer viruses can be difficult to detect as they hide in existing program files but are distributed to other programs similar to biological viruses.
- Worms: These are stand-alone viruses that automatically spread to other networks by themselves.
- Keyloggers: Similar to spyware, keyloggers collect your personal as well as financial information.
- Trojans: Trojans is nothing but a trick program that can be as destructible as computer viruses but does not replicate itself like a virus.
- Rootkit: Rootkit is installed by humans but is usually difficult to find.
- Backdoors: Backdoors are spam programs installed by hackers for unique destructive purposes.
- Adware: Adware disrupts your PC when you click on the pop-up ads created by companies that eventually need your installation support.
Emphasizing the importance of antivirus use
Nowadays, we give away too much of our personal information on our system to make website log-ins and user identification easier. While there are several reasons to invest in good antivirus software, the most important is to protect user identity because it’s a risk leaving it open to exploitation. The best antivirus software offers 100% protection against advanced risks and cyber threats, such as phishing websites, network hacks, financial theft, and more.
Most internet users often forget the importance of a good antivirus tool because they feel that the in-built security software in their PCs is capable enough to shield them against cyber-attacks and threats. Some people also claim that you can protect yourself without an antivirus, but the reality is that antivirus software fills the gaps in a user’s cyber defense. The software does so by:
- Helping you detect malware attacks before they cause harm to your PC. Antivirus tools are designed to scan infected files that pose a massive security threat. Consequently, they alert you of specific malicious activities, making you aware beforehand.
- Antivirus software helps shield your shared networks against ransomware and Trojan horses.
- Anti-virus tools also speed up your PC’s performance by decluttering cached threats.
- Antivirus apps protect and secure your data, besides protecting your documents and files from being corrupted and lost.
Antivirus software like Bitdefender comes with scanners that use different methods to address malware before it can make destructive changes to your PC. It is the characteristic of malware to hide in seemingly uncorrupted files like images, movies, MP3s, and system files. Generally, it is quite impossible to detect malware simply by looking at a file. This is why high-quality and reliable defenders are very important.
Note: Installing antivirus on your PC protects it from all kinds of threats and risks. But you may refrain from doing so considering the expense of buying it. Instead, you can check out these Bitdefender discounts and find the best deal for securing your PC.
Antivirus scanners used a few recognized methods to detect malware:
- Machine learning: Machine learning and behavior analysis are the latest malware detection tools, capable of addressing zero-day threats. Only certain antivirus programs offer machine learning in their engines.
- Heuristics: Computer viruses can be altered or encrypted to deceive anti-virus tools. Antivirus scanners, based on heuristics scanning, are useful to overcome such situations through logical assumptions by scanning seemingly safe files, unmasking encrypted malware.
- Malware database: Malware database is the most common method used by inbuilt virus scanners like Apple File Quarantine and Windows Defender. Malware databases can identify the newest threats as they are equipped with thousands of known and updated malware.
- Sandboxing: Sandbox provides a virtual artificial environment where files running in a sandbox are unable to corrupt system files that exist outside the sandbox. The sandbox makes any alteration made by malware disappear as soon as it’s closed down.
Conclusion: PC security is personal security
Irrespective of the internet device you are using, there are quite a few significant threats when you go online without proper antivirus security. Even if you feel that you can run your PC without an antivirus, you are at risk of losing your online identity and financial information to hackers and cyber threats. So, protect your data, your PC, and your identity today.
