Security software maker, Panda Security, recently compiled a list of the most interesting viruses of the past six months. Among these are the creepiest, cleanest and most informative viruses.

The creepiest - MalwareProtector2008 and AdvancedXpFixer fill victim computers with bugs which then "eat" the desktop. The virus is in fact an attempt to get users to buy the security software offered by the maker of the virus.

The cleanest - Tixcet.A cleans hard disks, by deleting the user's files.

The kidnapper - PGPCoder.E is also called "ransomware". The virus encrypts data on the user's hard disk and then demands money for the key to decrypt the information.

The most romantic - The Nuwar.OL, Nuwar.QI and Valentin.E clan use romantic themes to trick users into activating them and then infect their computers.

The most informative - Despite its name, Romeo.C is actually informative. Besides fiddling with the Windows registry, Romeo.C also displays a list of breaking news while carrying out its malicious actions.

The impostors - Manclick.A, Manclick.B and Manclick.C pass themselves off as other programmes to make potential victims think they are installing a legitimate application instead of malware. They also redirect users to spoof bank Web pages, to collect confidential information which is then used for online fraud.

The most deceitful - The FakeDeath worm announces the death of Fidel Castro to trick users and infect their computers.

The prophet of the Apocalypse - When run, RenameLoi.A makes an annoying noise and displays a message about the Antichrist and Judgment Day.

The cool pig - When users run a file containing the MSNWorm.EI code, the worm displays a photo of a pig with makeup, necklaces and sunglasses.

The noisiest - BeepBeep.A emits a series of annoying noises when users access the Windows or System folder.

安全軟件制造商——熊貓衛(wèi)士，進來羅列了一張過去六個月以來最有趣的病毒清單。其中有最令人毛骨悚然，最愛干凈以及最具教育意義的病毒。

最令人毛骨悚然的病毒：惡意軟件Protector2008和升級版XpFixer會使中毒電腦充斥著吞噬電腦桌面的蠕蟲。該病毒實際上是試圖讓用戶去購買由病毒制造者所發(fā)行的安全軟件。

最愛干凈的病毒：Tixcet.A會通過刪除用戶的文件清空整個硬盤。

勒索軟件：PGPCoder.E也被稱作“贖金軟件”。病毒將用戶硬盤上的數(shù)據(jù)轉譯成密碼，然后向用戶勒索金錢來換取鑰匙解碼硬盤上的信息。

最具浪漫氣質的病毒：Nuwar.OL，Nuwar.QL以及Valentin.E族類都運用浪漫的主題來誘使用戶啟動病毒，然后感染電腦。

最具教育意義的病毒：除了它的名字外，Romeo.C確實頗具教育意義。除了篡改注冊表以外，Romeo.C在實施惡意攻擊同時也會想用戶展示一系列重大新聞。

最會偽裝的病毒：Manclick.A，Manclick.B和Manclick.C會把自己偽裝成其他程序使得潛在受感染電腦認為它們正在安裝一個合法程序，而不是惡意程序。它們會將用戶導向一個欺詐性的銀行網(wǎng)站，以此來搜集用戶的私人信息并在接下來用于網(wǎng)絡欺詐。

最騙人的病毒：假死蠕蟲病毒發(fā)布了菲德爾卡斯特羅的死亡消息來欺騙用戶并感染電腦。

世界末日的預言家：當該病毒啟動時，RenameLoi.A會制造出很惱人的噪音，并且顯示出一條關于反基督教和審判日的消息。

酷酷的豬：當用戶運行一個包含MSNWorm.EI的文件時，蠕蟲病毒就顯示出一只著濃妝，戴著項鏈和墨鏡的豬豬。

最吵鬧的病毒：當用戶訪問Windows或系統(tǒng)文件夾時，BeepBeep.A會發(fā)出一組惱人的噪音。
