Sophos Clean

Sophos Clean is designed to detect viruses, Trojans, rootkits, spyware and other malware on modern and fully protected computers. It is the next generation technology for fighting malware. Sophos Clean removes persistent threats within the operating system and replaces infected Windows resources with original safe versions. Reinfection attempts are proactively blocked until remediation is complete.

Instead of looking for typical attributes of static malware, Sophos Clean looks for unethical behavior. It is much harder for malware to radically change the manipulative behavior of its malware than it is to change its static attributes. By combining forensics, behavioral and collective intelligence, Sophos Clean is one of the most effective solutions for fighting new and resilient malware.

The tool does not need to be installed. You can run it from a USB flash drive, from a CD/DVD or from network storage, which is good if the malware is tampering with installed antivirus software and its updates.
