Free and Portable Spyware and Malware Scanner

SpyBot Search & Destroy Portable is a free, portable application, which can be used to detect and remove spyware, malware and other malicious threats. Unlike the main version of SpyBot, the portable version does not need to be fully installed, allowing it to be put on a memory stick and used on multiple machines. The software is easy to use and comes with excellent ‘Help’ files, meaning no in-depth knowledge is required. Scanning is thorough and can be optimized to meet specific needs, although the advanced options mean it is technically possible to accidentally remove essential files.
