Can proxies prevent viruses? Yes. One of the ways proxies can protect against viruses is when you are using public Wi-Fi services that have Internet security features such as encryption and masking enabled. While proxies are not full-fledged antivirus software suites, private proxies can assist computer firewalls and more. However, you must realize that you are still prone to malware, hacking, etc., if you use proxies carelessly.

Understanding Virus Threats

Malicious software comprises computer instructions that can attack computers in various ways. Your computer could get a malware infection when you visit a dangerous website, install a new application, or open suspicious attachments in an email. If infected files are unknowingly send to other people, the malware may spread to their systems too. With that in mind, computers on a network are at risk because malicious code can be moved from one computer to another within the same network server.

How Proxy Servers provide Protection

Today, many people secure their computers with programs such as Avast or Norton Antivirus. Modern computers also offer users the option to enhance security with firewall features. Firewalls are designed to protect users and their computers by monitoring both incoming and outgoing network traffic. Dedicated and private proxies have features that help firewalls monitor incoming information, log ongoing activity, and filtering that information before it reaches the computer.

That’s why proxies have the ability to handle outgoing information that comes from web browsers. It is able to scan information for potential malware and prevent it from being further distributed over a network and infect other computers.

Large companies are known to utilize private proxy servers that can block incoming traffic from connecting to machines that contain sensitive company information. Some of that traffic may include cookies, which can be used by hackers to send malware onto other computers. Proxies do not pass such data to the end user.
