Sunbelt’s Top 10 Malware Threats for July
Sunbelt Software has released its Top Ten Malware Threats for July, compiled from scans by its Vipre AV and CounterSpy anti-spyware tools. Top of the list (again!) is Trojan.Win32.Generic!BT; but this is perhaps not surprising since it has a large number of variations and is a favourite for rogue software downloads. SpywareRemove defines it thus:
Trojan.Win32.Generic!BT is a vicious Trojan infection which has over 850 malicious variations. Statistics show that Trojan.Win32.Generic!BT tops the list for malware infections in 2009. Trojan.Win32.Generic!BT is very difficult to detect and remove and it is recommended that a proven anti-malware program be used to terminate this parasite. Symptoms include fake system scans and results and a reduction in system speed. Trojan.Win32.Generic!BT poses a huge threat to the security of your PC and should be removed immediately.
Trojan.Win32.Generic!BT is a generic risk that covers a lot of malicious applications. About 120,000 traces are identified under that detection by VIPRE’s signature-based, heuristic or behavioural mechanisms. Very often it identifies the downloaders that are used with rogue security programs, also called ‘scareware.’ Once they get downloaded, the rogues pretend to scan your computer for malware then display false warnings that the machine is infected. They try to convince victims to purchase useless security software, that often contains more threats.

Worryingly, Zbot, the nasty financial detail stealing trojan is at number two; and surprisingly, Conficker is still around and active at number six. Newcomers include Trojan:Win32/Meredrop (described by the MS Malware Protection Center thus “Trojan:Win32/Meredrop is a generic detection for Trojans that drop and execute multiple malwares on a local computer. These Trojans are usually packed, and may contain multiple Trojans, backdoors, or worms. Dropped malware may connect to remote Web sites and download additional malicious programs;” and Trojan.Win32.Generic!SB.0 (described by Sunbelt as “the generic detection for password-stealing Trojan horse programs that install keyloggers which record keystrokes and send the data to the malicious operators who distributed the malware”).
All in all it looks pretty rough out there. So keep your AV up to date and your OS fully patched!
