It’s time to stop believing these lies about antivirus software

The proliferation of social media misinformation, deep fakes, and sophisticated phishing attacks has made online safety challenging. Many individuals hold outdated beliefs about cybersecurity, such as the myth that Macs are immune to viruses and that caution alone can replace antivirus software. Regardless of the operating system, using a robust antivirus program is recommended, as built-in security features are not foolproof. Third-party antivirus software can provide additional functionalities like parental controls and VPN services, but they are not a complete safety net. Users must remain vigilant and practice good cybersecurity hygiene, including regular scans, strong passwords, and recognizing phishing attempts. Modern antivirus programs have become more user-friendly and less resource-intensive. Some malware can operate stealthily, making detection difficult, which emphasizes the need for regular scans and monitoring personal accounts for unusual activity. Antivirus protection should extend to mobile devices as well, as they are also vulnerable to cyber threats. Users should check if their antivirus program covers mobile devices and familiarize themselves with security settings on their smartphones.

Do I need an antivirus and a VPN?

Reliance on antivirus software for device protection is common, but certain threats, especially ransomware, can bypass even the best solutions. Cybercriminals have shifted tactics from encrypting data for ransom to exfiltrating sensitive information and threatening to leak it. The availability of ransomware kits and the use of AI by attackers have made cybercrime more accessible and targeted. Remote work environments increase vulnerabilities, as hackers exploit unsecured networks and personal devices. Antivirus software can help protect against malware and viruses, but built-in solutions often lack comprehensive security. A high-quality antivirus program can enhance protection through advanced features and AI. A Virtual Private Network (VPN) encrypts data and secures internet traffic, making it a valuable tool for cybersecurity. Implementing a VPN is cost-effective compared to potential data breach costs. Using both a VPN and antivirus software is essential for comprehensive coverage, as they address different security aspects. Businesses may need advanced endpoint protection solutions for heightened security, which continuously scans for suspicious behavior and integrates multiple security features. Despite these tools, proper personal practices and cybersecurity awareness are crucial to minimize vulnerabilities and human error, which is a leading cause of cyberattacks.

I learned these 6 antivirus myths for PCs are completely wrong

Antivirus software on Windows was once essential due to security vulnerabilities, but built-in protection in Windows 8 and later versions often suffices for everyday use. Modern third-party antivirus applications are designed to be efficient and have minimal impact on system performance. All operating systems, including macOS, Linux, iOS, and Android, are susceptible to malware, contrary to the belief that only Windows needs antivirus protection. Manual virus scans are no longer necessary as modern solutions provide real-time monitoring. Antivirus software should be part of a broader security strategy that includes regular updates and secure online practices. Relying solely on cautious behavior is insufficient, as threats can emerge from various sources. Using antivirus software is still recommended, and users can complement built-in security features with third-party solutions.

How we test antivirus software

Robust antivirus software is essential for protecting sensitive data in personal and business contexts. Different antivirus solutions vary in malware detection and overall protection. The ideal antivirus balances comprehensive coverage with system performance. Resources like AV-Comparatives and AV-Test provide impartial testing of antivirus capabilities, including real-world protection tests and evaluations of false alarms. Performance and customer support are critical factors in antivirus software evaluation. The impact on device speed and resource consumption is important, as is the quality of customer support for troubleshooting. Reliable support options enhance user satisfaction. Thorough testing of antivirus software is crucial due to the evolving tactics of cybercriminals. Not all antivirus solutions are equally effective, and rigorous evaluation helps identify subpar options and false positives. Free antivirus options may suffice for casual users, but premium versions often offer better features and protections. Meticulous testing ensures that security software meets its promises and helps users make informed decisions.

A Trojan-Downloading Website Is Imitating a Popular Antivirus Website

Hackers are increasingly using sophisticated techniques to entice users into downloading malware, with many individuals still falling victim to basic social engineering tactics. A counterfeit website mimicking the legitimate antivirus program Bitdefender has been created, which could mislead users. This spoofed site hosts a bundled executable named StoreInstaller.exe that contains malware configurations linked to VenomRAT, capable of remote access, credential theft, keylogging, and data exfiltration. The counterfeit site closely resembles the legitimate one, making it difficult for untrained users to distinguish between them. Users are advised to download antivirus software only from reputable sources and to verify the authenticity of the website before proceeding.

How to run an antivirus scan on your computer

When selecting antivirus software, understanding its functionality is crucial to ensure adequate protection. Running a virus scan involves opening the antivirus program, clicking the ‘Scan’ button, and allowing the software to operate. Automated scan schedules are important for consistent protection, especially during system startup to catch hidden malware. Key points for executing scans include avoiding heavy applications during the scan, utilizing the ability to pause scans, and ensuring laptops are charged and plugged in. During scans, the antivirus may identify potentially unwanted programs (PUPs), which should not be dismissed. After a scan, reviewing the results is essential, including threat names, severity ratings, affected files, and recommended actions. If threats are detected, correlating them with known vulnerabilities is advisable. Some malware may require a device restart or boot-time scanning for removal. Maintaining exportable logs can be beneficial for future reference. Post-scan, it is important to patch operating systems, change passwords if necessary, perform system backups, and establish a regular backup plan. Most antivirus programs offer features for automated scans and real-time protection, which should be utilized. Regular checks of reports are necessary to stay informed about device security. To maintain virus-free devices, users should avoid unknown links or email attachments, download software from legitimate sources, use strong passwords, back up important files, keep browsers updated, and enable multi-factor authentication. Regular virus scans are vital for safeguarding online presence and preventing performance issues.

Defendnot Disarms Windows Defender by Pretending to Be a Friend

A newly developed security program called Defendnot can deceive and disable Windows Defender, even without legitimate antivirus software installed. It alters the system to appear as a genuine antivirus program, allowing hackers to neutralize Windows Defender's protective measures. Defendnot operates through an undocumented API that antivirus software uses to register with the Windows Security Center, causing Microsoft Defender to deactivate. Developed by security researcher es3n1n, Defendnot injects a DLL file into the Taskmgr.exe process, misleading Windows into believing an antivirus is present. Although created for research purposes, it can be misused by cybercriminals. Microsoft Defender recognizes Defendnot as a Trojan and quarantines it upon detection.
