Common Linux Antivirus Myths Debunked
Here are some very interesting myths you’ll be hearing a lot from developers or other people, let’s debunk them together!
Myth 1: 100% Protection with an Antivirus
In reality, antivirus software is only a small component of a larger cybersecurity plan. To ensure total security, use two-factor authentication, software upgrades, safe browsing, and password management.
Myth 2: Computers with Linux antivirus software run much slower.
The truth is that contemporary antivirus programs are designed to run in the background without causing appreciable lags in performance.
Tip: Install a single, high-quality antivirus program, plan scans for off-peak times, and select “silent” or “gaming” modes for jobs requiring a lot of processing power.
Myth 3: Malware Cannot Affect Open Source Software
Another myth is the idea that malware cannot infect open-source software by nature. Although Linux’s open-source design makes it possible to find and fix vulnerabilities more quickly, this does not preclude attacks. Despite updates and patches, Linux systems are still susceptible to malware, phishing scams, and vulnerabilities.
To stop such breaches, antivirus systems provide an additional line of defense.
