Short bio
Type of infection
After arriving and executing on a target system, worms can perform a number of malicious tasks, such as dropping other malware, copying themselves onto devices physically attached to the affected system, deleting files, and consuming bandwidth. Worms can infect systems coming from connected systems or devices.
Protection
Malwarebytes protects users from worm infections by using real-time protection.
Home remediation
Malwarebytes can detect and remove worms without further user interaction.
It is important to identify the source of the infection as it may be able to re-infect the cleaned system. And check all the systems and devices that were connected during the time of the infection.
