A Complete Guide to Flame, the Malicious Computer Virus Ravaging
Iran     How far reaching, exactly?   From most infected to
least infected, it has reached Iran, parts of Israel and
Palestinian territories, Sudan, Syria, Lebanon, Saudi Arabia,
Lebanon and Egypt.   That sounds pretty invasive. How,
technically, does it work?  This very thorough explanation from
the Kapersky Lab, albeit a little technical, does a wonderful
job describing how the virus does its thing. As Kapersky
explains it, the virus is a 20 megabyte "sophisticated toolkit,"
even more complex than previous viruses that have attacked
Iranian computer system. This one shows characterstics of being

webopedia. And, Trojan makes it look like harmless software when
