4. MALWARE AND ANTIVIRUS

4.4. How to Detect, Remove and Prevent a Malware Infection

As it was mentioned before, just by perception and observation, sometimes it is possible for users to detect the presence of malware infections and attacks. However, not always it is possible to detect and even so the systems are compromised. In this case, just like in human health, also in systems and network, there are several tests that may be applied to make sure everything is free from infections and the information is secure.

Many security software are developed to detect and prevent malware infections and attacks, being also able to remove them. Working similar to a antivirus scan, antimalware apps run a scan on the computer, detecting and identifying infections, providing users with the choice of removing them or keep the files under quarantine.

An example of an antimalware is the known Malwarebytes, which handles both detection and removal of infected files and registries. It works under Microsoft Windows, MacOS, Android and iOS platforms.

Another good example is the free tool installed on Microsoft Windows machines above version 10, called Windows Defender. This tool is able to protect the local computer against threats like spyware, adware and viruses.

Regarding the prevention of malware attacks and infections, there are several different ways for systems and network protections. In the specific case of a personal computer, its is done by the installation of a simple antimalware software, like the ones mentioned above. Though, the application by itself is not enough to keep a proper protection, where users need to also practice a safe behaviour on their devices. This include not opening attachments from untrusted senders and accesses to untrusted websites.

Moreover, such antimalware applications should have periodic updates and scans, as hackers continuously adapt and develop new techniques to breach security software. In addition, security software developers also periodically release updates to patch those vulnerabilities. If users neglect to update their security tools, those patches are not applied, leaving them vulnerable to preventable exploits.

In enterprise environments, where networks and systems are larger than simple home networks, the severity of an attack has much higher damages. Here, some proactive steps are a must to enforce malware protection:

·      Implementing dual approval for business-to-business (B2B) transactions;

·      Implementing second-channel verification for business-to-consumer (B2C) transactions;

·      Implementing offline malware and threat detection to catch malicious software before is spreads;

·      Implementing allow list security policies whenever possible;

·      Implementing strong web browser-level security.
