September 6 marks detonation day for one of the most widespread Internet worms Kaspersky Lab, an international data-security software developer, warns computer users of the Septemeber 6th activation of the destructive functions wielded by the Internet worm KLEZ.E - one of the most widespread malicious programs of the year. Users run the risk of losing important data and the fruits of much hard work. "KLEZ" has truly become a big-time network curse on a global scale. The worm was first exposed in the spring of 2001. By February 2002 the worm handily held on to its top position in the list of the most widespread virus threats. This August's Virus Top Twenty tellingly confirms that at this time, one of the worm's modifications, "KLEZ.E", represents a significant threat to the Internet users. This is why we still have not observed the tendency for the situation to gradually improve. Presently, eight modifications of the worm are known. On the 6th of each month, one of them, "KLEZ.E", activates its destructive payload and wipes out all the data on infected computers. The only way victims can restore their data is from back-up copies saved on independent disks or tapes. "Users may not even suspect that their computers are reluctant hosts to the worm. "KLEZ" is practically unnoticeable until the day it unleashes its wrath - in this case, September 6th. On this day many risk forever loosing the result of much hard work", comments Denis Zenkin, Head of corporate communications for Kaspersky Lab. Kaspersky Lab reminds users of this dangerous threat and recommends, once again, the importance of taking preventative measures in order to avoid the possible penetration of "KLEZ.E". You may utilize Kaspersky® Anti-Virus to perform a computer diagnostic or you may take advantage of the free-of-charge "worm cure" utility. Additionally, Kaspersky Lab advises the immediate installation of the patch fixing the Microsoft Internet Explorer security system vulnerability exploited by "KLEZ" to gain penetration and infect computers. This will help avoid repeated infections and also prevent attacks from other "KLEZesque" worms appearing in the future. Useful Links:
