Sunbelt Software Announces Top 10 Malware Threats for November

December 3, 2009

CLEARWATER, Fla., Dec. 3 /PRNewswire/ — Sunbelt Software, a leading provider of Windows security software, today announced the top 10 most prevalent malware threats for the month of November 2009. The report, compiled from monthly scans performed by Sunbelt’s award-winning anti-malware solution, VIPRE® Antivirus + Antispyware, and its antispyware tool, CounterSpy®, is a service of SunbeltLabs(TM).

For November, SunbeltLabs reports that after seven straight months as the number one threat, the password-stealing Trojan-Spy.Win32.Zbot.gen is no longer the top threat. It has been replaced in the top spot by Trojan.Win32.Generic!BT, which accounted for almost 20 percent (19.82 percent) of all global malware threats in November. Trojan-Spy.Win32.Zbot.gen is the second most prevalent piece of malware accounting for 6.00 percent of all threats, which is a drop off of more than 41 percent from its 8.48 percent level in October.

New to this month’s top 10 list are Trojan.Win32.Generic!SB.0, which is premiering in the number three spot with 4.19 percent of detections, and Exploit.PDF-JS.Gen (v) at number six with 2.97 percent. Meanwhile three detections from last month’s top 10 list dropped out of this month’s list, though just barely: Trojan.Win32.FakeXPA (v) with 2.18 percent of detections, Packed.Win32.Tdss.Gen (v) with 1.74 percent and Trojan.1 with 1.53 percent.

“Trojans are the preferred malware tactic cyber-criminals use to commit social engineering-based attacks,” said Michael St. Neitzel, Sunbelt Software vice president of Threat Research. “The fact that six of the top 10 malware threats are Trojans demonstrates the ubiquitous nature of these threats. Everyone should think about security before they open attachments in email, click on links in email messages or posts from social networking sources.”

The top 10 results represent the number of times a particular malware infection was detected during VIPRE and CounterSpy scans that report back to Sunbelt’s community of opt-in users. These threats are classified moderate to severe based on method of installation among other criteria established by SunbeltLabs. The majority of these threats propagate through stealth installations or social engineering.

The top 10 most prevalent malware threats for the month of November are:


1. Trojan.Win32.Generic!BT                      19.82%
2. Trojan-Spy.Win32.Zbot.gen                     6.00%
