The Conficker worm aka Downadup worm continues to infect non-patched Microsoft computers a year after the initial outbreak. This worm scans your network and finds and infects other computers that are also not patched with the Microsoft MS08-067 critical patch. The worm can effect network performance since it floods the network with traffic while it scansĀ for other hosts to infect. It’s not in the news anymore since most companies have updated their systems, but just as many have not and are still vulnerable to attack. So get patched and update your anti-virus software.
