(From PC Magazine)  Kaspersky is one of the leading anti-virus companies, and in June they released their ranking for the top 10 best (or worst) malicious software designs of the year.

Lets just say that if you get one of these, you have got a problem!

1. Greediest Trojan targeting banks: Trojan-Spy.Win32.Banker.aqu, a modification that targets 87 banks simultaneously.

2. Greediest Trojan targeting e-payment systems: Trojan-PSW.Win32.VB.kq, which targets four e-payment systems.

3. Stealthiest malicious program: Backdoor.Win32.Hupigon.rc, packed ten times with a whole range of packers. Nevertheless, this didn’t save the backdoor from detection.

4. Smallest malicious program: Trojan.DOS.DiskEraser.b, smart enough to delete data from disk.

5. Biggest malicious program: Trojan.Win32.KillFiles.ki, the most space-hungry malicious program in May. This file-deleting Trojan weighs in at a whopping 247MB. Interestingly enough, May’s smallest and largest programs both have the same malicious payload—but the difference in size is remarkable.

6. Greediest Trojan targeting payment cards: Trojan-PSW.Win32.VB.kq wins the prize in this category; it targets four payment card systems, and interestingly also targets e-payment systems (see the above category).

7. Most malicious program: Backdoor.Win32.Agobot.afy, which deletes antivirus programs using a variety of methods.

8. Most common malicious program in e-mail traffic: Email-Worm.Win32.Netsky.t, Despite being an old-timer, this worm is still causing major damage, accounting for over 15% of all malicious e-mail traffic in May 2007.

9. Most common Trojan family: the winner of this category this month is the Backdoor.Win32.Rbot family, with 454 modifications in the course of just one month.

10. Most common virus/worm family: the Warezov family once again took this title this month. A total of 78 different variants of the Warezov family were detected in May, up from 72 in April.
