Every week we bring you an overview of the current viruses, worms, and other threats and the information you need to combat them. The first week of the month brings us the top ten (or twelve) malware reports from many of the antivirus vendors for the previous month. We've seen few new additions, but the ones listed are still infecting heavily. A buffer overflow problem in the widely popular WinZip archive program was reported on Sept 2nd. The vulnerability could be exploited by a specially crafted command line for Winzip. The past week has been relatively quiet, with a new version of MyDoom (Mydoom.T), and Bugbear (Bugbear.M), but neither has been spreading. On Monday, a mass mailing worm called Blackmal.C, also known as NyxemD, Mywife.C, Blackworm.C or Blueworm.C was detected. While not a major threat yet, Blackmal.C-mm does remove a victim's antivirus defenses. See the Security Watch Letter for more on these threats and solutions http://eletters.pcmag.com/zd1/cts?d=81-1079-14-15-53809-99947-1 IN THIS ISSUE: * Top Threat: W32/Blackmal.C-mm * Top 10 viruses and malware for August * Top 5 Vulnerabilities as reported by Threat Focus for Tuesday, September 8th * Security Tip: Clean up that Boot * Windows vulnerabilities and updates. * Jargon Watch * Security Watch News Feed. ============================================================ Top Threat: W32/Blackmal.C-mm W32/Blackmal.C-mm, also known as MyWife.C, is a mass mailing worm that sends itself to contacts in Yahoo Pager (IM), MSN Messenger, as well as harvesting addresses from the victim's hard drive. It launches the Windows Media player when it infects. The virus disables and deletes executables from popular antivirus programs. Due to high CPU usage, it effectively blocks the use of the PC. See our Top Threat to learn how to recognize and combat this new virus. http://eletters.pcmag.com/zd1/cts?d=81-1079-14-15-53809-99950-1 ============================================================ Top 10 viruses and malware for August The following are the top ten viruses and malware as reported by MessageLabs, McAfee, Symantec, Central Command, Panda and Kasperski for the month of August.

The more things that are loaded at startup, the slower the boot process, and the less room later for other programs. Spyware, adware, and browser hijacks all add stuff to the startup, as do many well-meaning programs, such as Media players, and OEM help systems. To learn how to clear your startup process with a little known utility, see our Security Tips section http://eletters.pcmag.com/zd1/cts?d=81-1079-14-15-53809-99959-1 ============================================================ Windows vulnerabilities and updates. As if using Kazaa and Grockster P2P file sharing services weren't hazardous enough with the threat of viruses, now you may be open to a buffer overflow vulnerability. Secunia is reporting a highly critical flaw in both Grokster and Kazaa. Windows XP SP2 has been out for several weeks and there have been reports of failed installations due to one thing or another. Learn more about these vulnerabilities, and how to cope with failed installs in the Windows Update and Vulnerabilities section. http://eletters.pcmag.com/zd1/cts?d=81-1079-14-15-53809-99962-1 ============================================================ Jargon Watch Each week, we define a few pertinent terms to break down the jargon barrier and help you better understand potential PC issues.
