Small Business Malware Protection

Cyber-attacks can make your business vulnerable to data breaches and impact your reputation, operations, employees and finances. Cox MalBlock safeguards your network against a variety of common online threats, including:


Botnets are software robots remotely controlled by a hacker trying to gain control of your network system. These bots have been infected with malware designed to steal critical information stored on your network-enabled devices.


Ransomware is a type of malware typically deployed through spam e-mails. Using ransomware, hackers can hold your organization’s files, databases or applications hostage.


Viruses come disguised in many forms, such as email attachments or Internet downloads. A virus can quickly spread throughout your network spamming your email contacts and stealing critical data.


A computer worm spreads copies of itself throughout your devices. Worms can modify or delete your files, deplete your bandwidth and allow hackers to gain control of your network.


Spyware is an invisible application designed to track devices on your network. The longer spyware goes undetected the more harmful it can be, giving cybercriminals access to your company’s passwords and sensitive information.

Trojan Horses

A Trojan horse is a delivery method where an attacker hides a malicious code within a valid software program that can be accidentally installed by users on your network. This type of malware can track your employees online and steal sensitive information.
