Viruses and malware have become the biggest concern for all major businesses, governments, and cybersecurity organizations around the world. In fact, according to the Cyber Threat Alliance, a powerful malware (ransomware) that goes by the name CryptoWall alone had caused more than $325 million worth of damage since January 2015.
The reason why modern viruses and ransomware programs are so powerful is that it is quite difficult for basic antivirus and security programs to detect them. These programs can stay dormant indefinitely, and made active by the attackers when a system is the most vulnerable. Attackers also use a variety of techniques to mask these programs making it difficult to detect them when they invade systems. Once they have infected a system then the only solution is to pay the demanded ransom.
There is no foolproof method for protection against virus attacks, except for using the best antivirus for Windows that you can find, and customizable firewalls. You can also create an online backup in advance to protect your data. This way, if a malware locks your files, then you can wipe clean your entire system and transfer the files again through disaster recovery.
The following are a few ways to protect your PC and keep it free from viruses:
Top-Quality Antivirus Programs
As mentioned above, you need nothing but the best antivirus programs if you want maximum security for your PC. Going cheap here can cost you your private data. So, it’s highly recommended that you use an advanced program like Bitdefender that offers multi-layered protection, updates its database on a regular basis, and includes a VPN feature that can secure your confidential banking data.
Backups are the best way to protect your files and data. It may seem cumbersome to create backups every day or week but in an event of a cyberattack, they can save you a lot of money and time.
It is important you create frequent backups for maximum protection. In fact, it is better if the backups are scheduled on a daily basis. Here are a few questions to ask yourself regarding this:
- Given the size and nature of your data, should you go for full backups or for incremental backups?
- Are you going to create backups of certain files locally?
- Which kind of data is the most important to you?
Keeping the Network Clean by Whitelisting (For Business PCs’ Protection)
Newer malware programs are hitting the Internet faster than ever, so much so that the companies have to constantly update their firewalls and antivirus programs. The only sure-shot way of keeping most types of ransomware at bay is to start implementing whitelisting.
Most typical antivirus programs use virus signatures and key identification patterns to detect malware and other similar programs, which is why they may ignore newer malware programs. However, by whitelisting you can ensure that the system runs only a limited set of applications and websites that have been chosen by you.
If possible, you can also use a browser like DuckDuckGo, which is one of the top privacy tools to use every day to add another layer of protection on top of whitelisting.
Modern viruses are incredibly powerful, and the recovery costs in an event of disaster are also quite high. Thus, you must take a multi-pronged approach to leave no room for vulnerabilities. Using top of the line antivirus software, whitelisting your programs, and creating regular backups can keep the malware at bay to a large extent. You can also consult with security professionals to deploy some enterprise-level measures too.
