Unlike many antivirus solutions, Kaspersky Free Cleaner is not a complete antivirus protector, but has a very specific remit of viruses that it can disinfect. The virus list that it eliminates is very limited, and numbers just ten at the moment. These bugs are pretty nasty though, and the fact that it is free means you don't have to pay to steer clear of them. The application looks in the memory, the registry, the hard disk (also in network units), the services and IRC spcripts for these viruses. The analysis does not take a long time, appearing within an MSDOS window and, if you have the misfortune of having any of the viruses in the list on your system, it will end them completely and without hassle.
