One of some useful free tools obtained by Kaspersky Lab is Kaspersky Virus Removal Tool 2010 or AVPTool 2010. This freeware tool can be used for curing computers infected with viruses and other malware. I’ve experienced using this tool for curing my collogue computer who’s accidentally clicking link into malware sites, and yet his antivirus is not good enough in protecting from malwares.  Since it is free, Kaspersky Virus Removal Tool 2010 has some difference with others Kaspersky commercial software (like Kaspersky Anti Virus or Kaspersky Internet Security) which is:

3. It only works by on demand scan mode. It does not have feature to work in real-time mode.
