Computer Viruses

I’m getting up to 100 emails a day. Most of these are viruses and spam, and are filtered straight into the trash because they are sent to an email address which the spammers have invented or a virus has randomly generated (all mail sent to straughan.com comes to me). Others I see, but they have become obvious and predictable and I delete them with hardly a glance at their contents.

One had a dangerous twist though. At the bottom of the (brief) email it included these lines:

++++ Attachment: No Virus found

++++ Norman AntiVirus – www.norman.com

This is very similar to the standard lines that many anti-virus programs automatically put into incoming email to let you know whether it’s clean or not. I had never heard of Norman anti-virus, and even thought it was a joke, since one of the popular anti-virus packages is from Norton. In any case, my anti-virus is AVG, so I knew this message was spurious. In fact, AVG had added these lines at the true end of the message:

Viruses found in the attached files.

The attached file ou.doc .exe is infected by I-Worm/Netsky.Q. The attachment was moved to the virus vault.”

So… even if a mysterious email with an attachment claims to be clean, don’t trust it. Make sure that it has truly been inspected and passed by your own anti-virus software. And again: NEVER OPEN AN ATTACHMENT THAT YOU’RE NOT EXPECTING TO RECEIVE, NO MATTER WHO IT COMES FROM OR WHAT IT CLAIMS TO BE.

I visited the Norman site, and find that they do indeed make anti-virus software. Since I had never heard of them before, I am tempted to wonder if they are spreading this virus themselves as a publicity stunt. Especially since I’ve just received a very similar email, but with the name of a different virus protection software company, again one I’d never heard of. Hmm.

Another thing to watch out for: spyware.


Then there are viruses whose random text hits below the belt:
“you are a bad writer”
“Let’us be short: you have no experience in writing letters!!!”

In light of Microsoft’s ongoing problems with hackers targeting its products, it seems wise to get as far away from Microsoft as possible, within the limits of the fact that many of us need to use Windows for our daily work. Last week’s reports of of a new hack which allows attackers to take control of your computer via Microsoft Internet Explorer finally jolted me into something I’ve been meaning to do for a while: change browsers. I took the advice of the Washington Posts’s tech columnist, and have switched to Mozilla Firefox. So far I find it very similar to IE in look, feel, and behavior, minus the dangers of hackers (for now).

 

More Virus Sneakiness

I received the following email last night:

“Dear user of e-mail server “Yahoogroups.com”,
Some of our clients complained about the spam (negative e-mail content) outgoing from your e-mail account. Probably, you have been infected by a proxy-relay trojan server. In order to keep your computer safe, follow the instructions.
Please, read the attach for further details.
For security purposes the attached file is password protected. Password is “87240”.
The Management,
The Yahoogroups.com team http://www.yahoogroups.com”

There was a password-protected zip (compressed archived) file attached.

The alarm bells started ringing in my head, even though my virus scanner had passed this attachment as clean. If Yahoo really had something to tell me, why would they put it in a password-protected file? I did NOT open the file, and I warned my fellow moderators of this Yahoo group not to open it. I turned to my group of expert friends for their opinions, and one told me he had recently received this warning from his ISP: “There’s a new virus on the loose that’s able to trick our antivirus program on our email server. It’s in a password protected zip file. Unfortunately, there is no method to scan password protected zip files, so our server sends it through.”

The moral of the story is the same as it’s always been: if you are not expecting a file from somebody, and/or anything seems strange about the situation, do NOT OPEN THE ATTACHMENT. You’ll save yourself and everyone in your address book a world of trouble.

Computer Viruses 4

Virus mutation is happening alarmingly quickly. I have gotten into the habit of updating my virus software almost daily. Nonetheless, something arrived in my mailbox the other day which my virus software passed as clean. But it was from someone I didn’t know, with an executable (.EXE) attachment, so I didn’t touch it. I updated my virus software and ran a check and, sure enough, it was a virus.

Even had this piece of mail claimed to be from someone I know, I would have been suspicious unless I had been expecting to receive such a file from that person right then. Many viruses disguise themselves with fake email addresses pulled from your own address book, and/or someone you know may be infected and not know it himself.

Another Reason to Secure Your Computer

Some viruses are now looking to turn your unprotected computer into a spam-generator, especially if you have a high-speed, always-on connection such as cable or DSL. Such abuse of your system could result in your service being cut off by your Internet Service Provider. Read all about it.

Computer Viruses 3

Since the MyDoom attack, I’ve gotten into the habit of updating my anti-virus software almost daily. What’s scary is that new updates have been available that often, meaning that new viruses are appearing that frequently (many of them variants on MyDoom). I can’t say it enough: UPDATE YOUR ANTI-VIRUS SOFTWARE. If it’s too old to catch the current bugs, it’s no use to you.

You may also have noted that there’s a new security hole in Windows discovered just about every week. Hackers may have even more opportunities to exploit Windows vulnerabilities, now that several million lines of Windows source code have been leaked, so be prepared for an increase in attacks. It doesn’t hurt to run Windows Update weekly, at least, to see if Uncle Bill has any new patches for his leaky boat.

Let Us Now Praise Amazon

The Best Source for English-Language Books in Italy

Enrico and I read a lot (Rossella, alas, does not). Our house is stuffed with books, many of which we have read several times over – if I don’t expect to want to read a particular book ever again, I give it away.

Obtaining books was a problem when we first moved to Italy. I do read in Italian, but prefer to read books in their original language when I can. The exception is mysteries, which I read in Italian because my mother-in-law has a huge collection, and I consider it a waste to buy them since I will read most of them only once.

There is one mid-sized foreign-language bookstore in Milan, but it’s expensive, as all the books are imported. So I had to depend on trips to the US or England, from which I would return loaded with books. I learned a little-known secret of the US postal service, the M bag: you pack up books in boxes and they stuff the boxes into a big canvas bag, which can be shipped surface mail for a special low rate. It’s so little-known that, in some post offices, I had to explain it to the counter clerk.

I first heard about Amazon around 1995. “An online bookstore? What a fantastic idea!” But sending books all the way from the US was a problem. I tried every option. FedEx was tremendously expensive, and airmail not much cheaper. Surface mail was tremendously slow. But I had to feed my book habit.

I was saved by the opening of Amazon UK. Packages can be sent fairly cheaply by ordinary British Royal Mail, and arrive within days. I was worried at first that non-couriered packages would simply disappear into the maw of the Italian postal service, as so many packages do. But Amazon was prepared to deal with that. The first time it happened, I emailed customer service, and a replacement package was sent immediately, this time by courier, for no extra charge. I became a fanatically loyal customer at that moment. The original package never did turn up; Amazon didn’t mind.

Later, I wrote to them when a large and expensive shipment of books (computer stuff) had not arrived after three weeks. “This could be the usual summer slowdown, so I’m willing to wait longer,” I said. They sent a replacement anyway and, sure enough, the original package arrived a few days after the replacement. “What should I do with these duplicate copies?” I asked. “Donate them to a school,” said Amazon, so I took them to Woodstock on my next visit.

This has happened several more times, but I’ve only been asked to send back DVDs. Books and DVDs that have gone permanently missing have been replaced without a murmur. The most recent example is the Firefly DVD set, which I ordered from Amazon US as soon as it was released, December 9th, along with a book for my Woodstock history research. I chose ordinary airmail – much cheaper than courier. The two items were shipped separately, the DVDs a few days earlier than the book. The book arrived on Dec 22nd, the DVDs still haven’t shown up. On December 30th I wrote to Amazon, again saying that I was willing to wait a bit longer and see if it had simply got lost in the holiday rush. Within two hours, I had a response: they were sending replacement DVDs. Now that’s customer service.

I wish other companies worked as well. Lands’ End opened a UK branch a few years ago, great news for me as I depend on them for turtlenecks and fleece jackets. (I hate shopping. Once I find something I like, I stick to it forever.) The prices were high: they decided that a 10-dollar item would cost 10 pounds, when the pound was actually worth about 30% more (now that the dollar has devalued further against the pound, there has finally been some price adjustment). But they have an overstocks section on the UK site, so I can often pick up items I like very cheaply. Sometimes I save on shipping by having things mailed to my dad’s house in the UK when I’m going there on a visit (which also means I can bring less clothing with me).

So, before my October visit to my dad, I browsed the overstocks section and picked out ten turtlenecks, each of them under 6 pounds. When the package arrived, it contained 11 items – one was a duplicate that I had not been charged for. I could have just kept it, but, scrupulously honest creature that I am, I decided to let them know what had happened. I emailed customer service, fully expecting them to say: “Just keep it, thanks for letting us know.” They didn’t. They wanted it back, which would involve a trip to the post office, although they offered to refund the postage. This for an item from their overstock section that cost about 5 pounds. Sheesh. Get a clue from Amazon, folks.

Feb 2, 2004

The lost Firefly DVDs turned up, almost two months after the original order was placed. I wrote to Amazon to ask what they wanted me to do. “As the cost of return shipping is prohibitively expensive in this case, we ask that you keep the duplicate order with our compliments. Perhaps you can donate it to a school or library in your area.”

As you have probably noticed, I am also an Amazon “associate”, meaning that, if you click from my site to Amazon and end up buying something, I get a percentage. In the third quarter of last year I finally made enough money this way to actually get a gift certificate: $18. Thanks to those who you who clicked through and bought!
