McAfee Stinger Portable is an antivirus application that you can take anywhere and run without installation thanks to McAfee and the PortableApps.com team.
Unlike other more complete tools, this program will not keep your computer under constant supervision since it is intended to be used mainly in case you suspect that a specific computer may be infected.
You will only have to run the application and do an analysis of the computer, after which the viruses that have been found will be eliminated. It is an ideal application for netbooks or low-income computers that cannot afford to have an antivirus, permanently consuming the system’s power. By taking some care and using this scanner from time to time, good protection can be maintained.
