Rootkit detection and removal
Our free software, Sophos Anti-Rootkit, finds and removes any rootkit that is hidden on your computer using advanced rootkit detection technology.
Rootkits can lie hidden on computers and remain undetected by anti-virus software. Although new rootkits can be prevented from infecting the system, if you had any rootkits before you installed your anti-virus, they may never be revealed.
Removing rootkits without compromising system integrity is particularly challenging and needs to be done with care.
Using Sophos Anti-Rootkit is easy. Whether you use its simple graphical user interface or run it from the command line, you can easily detect and remove any rootkits on your computer.
Easy to use
Sophos Anti-Rootkit provides an extra layer of protection, by safely and reliably detecting and removing any rootkit that might already have hidden itself on your system.
Stay free of rootkits
As part of its complete protection of endpoint computers, Sophos Endpoint Security and Control detects rootkits and prevents them being installed on any of your desktops, laptops and servers.
Spybot - Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications. Spyware silently tracks your surfing behaviour to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies. If you see new toolbars in your Internet Explorer that you haven't intentionally installed, if your browser crashes inexplicably, or if your home page has been "hijacked" (or changed without your knowledge), your computer is most probably infected with spyware. Even if you don't see the symptoms, your computer may be infected, because more and more spyware is emerging. Spybot-S&D is free, so there's no harm giving it a try to see if something has invaded your computer.

ZoneAlarm is designed to protect your DSL- or cable-connected PC from hackers. This program includes four interlocking security services: a firewall, an application control, an Internet lock, and Zones. The firewall controls the door to your computer and allows only traffic you understand and initiate. The Internet lock blocks Internet traffic while your computer is unattended or while you're not using the Internet, and it can be activated automatically with your computer's screensaver or after a set period of inactivity. Zones monitor all activity on your computer and alert you when a new application attempts to access the Internet. Version 7.0.362 may include unspecified updates, enhancements, or bug fixes.
Note:ZoneAlarm is free for individual and not-for-profit charitable entity use (excluding governmental entities and educational institutions). Advanced features are available.
