Viruses Find New Ways to Worm into Computers
Just when you thought you knew a computer virus or worm when you saw one, several new infections that may fool you are gaining momentum on the Internet.
Most e-mail viruses require the victim to double-click open an infected attachment before they can wreak their havoc. But Badtrans-B and Atiz, two worms that were spreading quickly over the weekend and Monday, can launch themselves automatically when the recipient views or even just clicks on the subject line of an infected e-mail message using Microsoft’s Outlook and Outlook Express programs. October’s Nimda virus used a similar technique, which helped it spread further and faster than it otherwise might have. Computer users were safe from viruses as long as they didn’t download programs from the Internet or open e-mail attachments. But these days, viruses are as capable of getting into computers as Santa Claus is at getting down chimneys.
Antivirus software maker McAfee, a division of Santa Clara, Calif.’s Network Associates, upgraded Badtrans-B to a high-risk virus for consumers. Vincent Gullotto, director of McAfee’s virus lab, said the worm is infecting more home users than corporate networks.
To prevent these and other viruses from automatically launching themselves, Gullotto advised down loading a software patch from Microsoft at www. microsoft, com.
Badtrans-B and Aliz have shown up with many different subject lines, ranging from the low key "info" to "Fw: Funky pictures -- check it."
Meanwhile, a worm called SirCam is still popping up regularly in e-mail boxes, months after it was first discovered. SirCam takes a Microsoft Word document from an infected computer and e-mails it out with a message reading "I send you this file in order to have your advice."
Gullotto attributed SirCam’s staying power to social engineering. SirCam takes the title of the Word file as its subject line, which means the virus might arrive labeled anything from "blJsiness plan" to "diary." It is those sometimes-intriguing subject lines that entice people to open SirCam-laden attachments and spread the virus, Gullotto said.
To protect against all of these viruses, experts advise that computer users install antivirus software and regularly update it from the company’s Web site. [br] What makes it more difficult to deal with the virus named SirCam?
选项
A、It will regularly pop up even when discovered.
B、It has a staying power in social engineering.
C、It takes the form of a Microsoft Word document.
D、It is labeled various intriguing subject lines.
答案
B
解析
根据提问,应在相关的段落找到有关的叙述。其中有一句概括地讲到Gullotto attributed sirCam’s staying power to social engineering。而选项C不正确是因为许多电邮都具文本形式或者带有文本附件,但不一定是病毒。选项D是指出了这种病毒带有许多诱人的标题,而带有许多诱人的标题也不一定是病毒。但这就像文本形式一样,也只是社会工程的一种具体的表现形式。遇到类似的考题时,如果有几个都提到过,看起来似乎都是正确的,就应注意选择具有概括性的完整意义的选项。
