The Truth About Computer Viruses

Forward this to everyone you ever met (even your dead relatives).

By Dan Kidder Consummate Debunker

There are approximately 46,000 known strains of computer viruses. Each year the number of false computer virus warnings and other virus hoaxes exceed the total number of true viruses by a ratio of about 6 to 1.

Why are there so many false viruses? My theory is that they are propagated by the very people creating viruses as a form of computer terrorism. It only follows that if enough false alarms are raised, people will grow lax in their security measures and will more readily fall victim to actual viruses when they strike. How many of you reading this report have anti-virus software? If you do have anti-virus software, when was the last time you downloaded the updates? Was it within the last week?

Whatever the reason, the chaos created by computer virus hoaxes outweighs any possible benefit. If a powerful computer virus strikes, you are more likely to hear about it from CNN, your radio disk jockey, and the local newspaper before your friends can warn you via e-mail.

"Almost every case of an e-mail message titled 'Forward this to everyone you know' is a fraud, a hoax or worse," claims one article from the Federal Trade Commission. That also includes e-mails that claim to give money, trips, or prizes to people who forward an e-mail to the most people and that e-mails are monitored using special tracking software. As of this writing there is no special tracking software capable of monitoring an e-mail through the many stages of forwards. There is however the possibility that the original sender will receive several threads of those forwards and can then create a mailing datalist from the e-mails listed on the forwards. That is why it is always a good idea to blind copy (bcc) large groups of recipients to an e-mail. I am sending this to all of you because I have your e-mails in the top of this letter and all of your address are listed at the bottom.

Usually a few seconds of time taken to verify an e-mail can prevent that crazy silly feeling when it turns out to be a hoax. But, how do you verify if an e-mail is true or a hoax?

The only authoritative source for virus warnings is the F-Secure Virus Warning Website. Started in 1994 as Datafellows, it was the first website devoted to the subject of viruses and is considered to be the industry standard for factual information about computer bugs.

Symantec, makers of Norton Anti-Virus also provides an authoritative site for virus warnings and patches to detect and cure them.

Microsoft has this official virus warning site.

The following is a response from the Federal Trade Commission which monitors Internet Fraud, but does not monitor viruses.

In my experience, messages that contain "Please forward this email to all your friends on the internet" are almost without exception either scams, hoaxes, or total nonsense (or some combination of the above). It is never wise to propagate them without verifying them first - it is usually a very bad idea. jump forward to Specific Hoaxes Introduction Because e-mail is so easy to send to so many people, it has become the new medium of choice for propagating rumors and hoaxes - as well as an occasional real warning or solicitation for a worthwhile cause. In the past year I've gotten many warnings and requests by e-mail - about supposed e-mail and other viruses, about "Make Money Fast" and other chain letters, about a campaign against cancellation of funding for radio shows, requests to send e-mail to increase a publisher's committment to donate books for children, and a metric boatload of unsolicted bulk or commercial e-mail. Some were worth reading and forwarding, and some were either hoaxes or unverified rumors that had been forwarded by well-intentioned people. When you get e-mail that says "please forward" or "pass this along," consider trying to verify the content before passing it on. Certainly verify first if the message asks you to send e-mail or paper mail to some address, or to call some telephone number - perhaps a perpetrator is trying to overflow someone's mailbox, or to run up toll-free number costs, or to induce you to make a toll call to a high-cost number - can you name 12 countries in North America area code 809? Be wary of e-mail messages that quote or invoke authorities without providing specific references - if the messages say "the FCC announced" or "researchers at IBM found" then you should expect to also see a URL like or or, for a real example: - FBI Fraud Alert

Spending 10 minutes with a WWWeb search engine looking for keywords from a warning could save you some embarrassment, and save each of your e-mail correspondents the same amount of time and trouble. If you find that a warning is a hoax, consider passing that information back to whoever sent you the warning, and perhaps along to your e-mail correspondents - and you may reduce the number of well-intended but spurious warnings that get mailed to you this year. If you find that a warning that you have already passed on is a hoax, well, welcome to the club - many people have been taken in by carefully written hoaxes, and have passed them on with good intentions. Specific Hoaxes Before August, 1998, it was generally thought that you couldn't get a computer virus just from reading e-mail. Messages about Good Times, Penpal Greetings, Deeyenda, Join the Crew, and other so-called "e-mail viruses" are well-known hoaxes. For confirmation, see: CIAC Internet Hoaxes

In August, 1998, a name tag security hole in several MIME-aware mail user agents was discovered. For details, see: FAQ about Mime Name Vulnerability

You CAN get a computer virus or other damage from running an infected program, or from running a word-processing macro virus in an infected document, and an infected program or document could be an attachment to an e-mail message. Widespread examples of infected attachments are "Happy99" and "Melissa". Happy99 is a trojan horse program that, if run, alters your Win95 or Win98 wsock32.dll file, and attaches copies of itself to your outgoing mail or newsgroup postings. happy99, ska trojan virus

The Melissa document-macro virus was widely reported in the media on and after March 26, 1999 - see the CERT report

If a message suggests sending cash by paper mail, you'll probably want to ignore it, or, if you care about the sender, return it to them. Pyramid schemes are fraud and chain letters are illegal in the US, see: USPS - Inspection Service Consumer Fraud

Neither Craig Shergold nor the Make-A-Wish foundation want your business cards, get-well cards, post cards, pull tabs, bottle caps, etc. Make-a-Wish never asked for cards. Craig did and got 16 million of them! Craig is not 13 and is not (any longer) dying of cancer - in fact, he turned 17 on June 24, 1996, and is doing fine.

The FCC does not issue virus warnings, but in late 1996/early 1997 it did hear and deny a request to allow local phone companies to make per-minute charges on local calls for dialup Internet connectivity. Rumors of a similar hearing/public comment period in early 1998 for this so-called "modem tax" are false - get clarification and details at: Fact Sheet on The FCC, Internet Service Providers, and Access Charges

In closing, let me suggest that you learn to evaluate everything you read in e-mail or on the Internet, just as you would evaluate what you read, hear, or see in other media, whether that medium is the local TV news, or a story you hear at a party, or a caller to a radio talk show, or a newspaper clipping in a letter from a friend.
