In a recent post, I recommended Panda’s Cloud Antivirus as a decent free antivirus program. Others have recommended different programs, and that’s fine – in the end, I don’t think there’s much meaningful difference between the various antivirus programs, at least in terms of security.
Much more important than which antivirus program you use (or anti-spyware, or firewall, or any security software), or even if you use one at all, are the practices that make up your online behavior. People who do risky stuff on the Internet will get a virus, sooner or later, regardless of how good their security software is. On the other hand, many security experts don’t use any antivirus software and still manage to avoid viruses.
I don’t recommend that you follow in the footsteps of the security experts – the nature of their calling demands a kind of paranoia that few of us can maintain. I recommend a solid package of security software (I run Cloud Antivirus and Windows Defender) but only as a safety net – something to pick up the slack when we make mistakes, not a first line of defense.Advertising
The thing with security, online or anywhere else, is that it’s always a trade-off between protection and convenience. I can tell you how to absolutely avoid any risk of computer virus, spyware, or trojan: stay offline and never install anything or use any removable storage media. That’s 100% perfect protection, but it would severely hinder your computer usage. It’s like securing a house: You could build a door-less, window-less titanium-sheathed reinforced-concrete bunker around your house and be absolutely sure burglars couldn’t get in, but you probably wouldn’t want to live there.
The tips below are sufficient to account for all but the most determined attacks against your computer. No amount of software or behavioral change can protect you from every possible attack (if the NSA wants to get on your PC, they are probably going to do so) but you can protect yourself from virtually all of the attacks you’re likely to face online.
I owe thanks for most of these tips to Leo Laporte and Steve Gibson, hosts of the TWiT netcast Security Now. If you’re interested in computer security at a very deep level, this weekly show is your ticket, and I heartily recommend it!
1. Use a router.
The very nature of the way routers works acts as an effective hardware firewall, preventing access to computers on your home network from outside the network. Put simply, when you request something from the Internet – say, you click a link, check your email, or enter a URL – the router notes which computer on its network the request came from so it can send the reply to the proper recipient. If a would be intruder attempts to enter your network, the router checks its list of outgoing requests and, if none is found correlating to the attackers’ IP address, it ignores it. It basically doesn’t know which computer to send it to, so it throws it out.Advertising
If you simply cannot use a hardware router, make sure your operating system’s firewall is turned on. This is almost, but not entirely, as good.
2. Do not open email attachments.
I know, who doesn’t want to see pictures of Anna Kournikova naked, right? Email attachments are a major vector for infecting computers, because it’s so easy to fake the sender so the email looks like it came from someone you know, and everybody loves opening attachments from people they know. It could be a funny picture of penguins, after all. But bottom line, don’t open attachments. If your email client automatically opens or previews them, turn that feature off. Even if it’s from your mom, and even if your mom says she opened it and it’s fine, still don’t open it. (By the way, next time you’re at mom’s, reinstall Windows. She’s got tons of viruses now.)
Now, I know that sometimes you have to open attachments, so here’s a simple test to know when it is most likely safe to open an attachment:
- You know that the email is from the person it says it’s from. That usually means that either they said they were sending it, or they’ve written a note that only they could have written.
- You are expecting an attachment from that person.
- You know the person who created the file.
- There is a compelling reason to open the attachment. I’m sorry, ma, but a good laugh isn’t enough to get me to risk my computer’s security.
If you can’t be absolutely, 100% sure on all these counts, trash it.Advertising
3. Do not download bittorrent files.
That sucks, I know, but since you’re never absolutely sure where the file comes from, where it’s been, or who might have altered it, bittorrent is risky. Downloading a Linux distribution from Ubuntu is probably ok; downloading it from Pirate’s Bay is a bit dodgy. Downloading Oscar screeners of movies that haven’t been released yet is super-duper dodgy. It’s a real shame to have to forego sticking it to The Man because of practical concerns, but you’re taking a big risk downloading an unknown file from an unknown person about whom the only thing you know is that they don’t feel any compunctions about breaking the law.
4. Do not download warez, porn, or other dubious files.
First they came for my bittorrents, then they came for my porn! It just gets worse and worse, doesn’t it. But really, think about it – people who distribute illegal copies of illegally hacked software a) are demonstrated lawbreakers, b) are familiar with programming code, and c) had access to the code you’re expecting to install on your computer. As for porn, while I’m sure there are plenty of Good Samaritans out there who distribute free pornography simply out of a desire for greater happiness in the world, some small number of them do it for financial gain. If they’re giving you free porn, they must be making money off you another way, and one of the easiest is to install a bunch of malware on your computer, run whatever code they want on it, and then sell the use of your computer to spammers, phishers, and other unsavory sorts. You want to know how bad these guys are? They don’t even care if they give pornography a bad name!
5. Do not download *anything* from sites you’re unfamiliar with.
Again, if you’re intending to install something you’ve downloaded onto your computer, you have to know that only people you trust have had access to it. Adobe, Microsoft, and other software manufacturers are generally trustworthy, as are sites like C|net’s Download.com. “Bob’s Free Software I Like a Whole Bunch” might not be quite as safe a bet.
7. Do not click links in email.
It’s very easy to hide the real destination of links sent in email by using HTML where the text reads “www.perfectlysafesiteyouknowandtrust.com” but the actual URL is “www.reallybadsiterunbymeanpeoplewithnofriends.net”. This is how phishing scams work – you think you’re going to PayPal or your bank, but really you’re going to a page designed to look just like your bank’s login page but hosted on the mean people’s server. Also, bad guys often put unique tracking IDs into links, so that they know exactly who clicked on a link – which means that they know which email addresses out of the millions they sent spam to are valid, which makes them worth more money to other spammers. Um, yay?
7a. Do not click shortened URLs.
I don’t like this one, because I like Twitter and you lose a lot of functionality if you don’t use a service like bit.ly or is.gd to shorten URLs, but these links are scary. When you hover your mouse over a link, the URL appears in the email or browser’s status bar, meaning you can verify that the link heads to where it says it does. When you do the same with a shortened URL, it just says the shortened URL. There are Firefox extensions like UnTiny that will reveal the true destination of shortened URLs, and some Twitter clients do as well, but until a universal solution is standardized, these URLs remain a bit scary, security-wise.
8. Install all security updates.
Unless you’re a multi-national mega-corporation running oodles of mission-critical custom-designed software, you need to install security updates as quickly as possible upon release. If remembering to do this isn’t something you think you’d be likely to do, set your computer to automatically download and install updates. Increasingly, we’re seeing “0-day” exploits – viruses and trojans written to make use of security flaws before those flaws are corrected by – or, in some cases, even known to – manufacturers. Keeping up-to-date is essential to keep even marginally safe.
I know that, the world being what it is, someone will be thinking right about now, “Hey, why don’t you just switch to Mac OS X or Linux?” It’s true, those operating systems get far fewer viruses and other problems than Windows PCs, but most experts seem to agree that this is at least in part because there are so many Windows PCs and so few Mac and Linux PCs. (There are plenty of Linux servers, but those are under professional supervision, which goes a long way towards making up for any security weaknesses Linux has.) Bad guys program for the system that allows the greatest spread of their malware, and right now, that’s Windows.
But if you’re still not convinced, I’ve got an even better idea for you. Both Mac OS X and Linux have demonstrated security vulnerabilities, and as they become more common are likely to become targets for hackers. So they’re not really safe bets. Instead, try BeOS! It may be riddled with security holes and only run on Pentium 4 and earlier PCs, but I can guarantee you, nobody is writing viruses for it!
For everyone else, whether you use Windows, Mac, or Linux, make sure to follow the rules above and, chances are, you’ll be just fine.

7 Steps For Making a New Year’s Resolution and Keeping It
Are you keen to reinvent yourself this year? Or at least use the new year as a long overdue excuse to get rid of bad habits or pick up new ones?
Yes, it’s that time of year again. The time of year when we feel as if we have to turn over a new leaf. The time when we misguidedly imagine that the arrival of a new year will magically provide the catalyst, motivation and persistence we need to reinvent ourselves.
Traditionally, New Year’s Day is styled as the ideal time to kick start a new phase in your life and the time when you must make your all important new year’s resolution. Unfortunately, the beginning of the year is also one of the worst times to make a major change in your habits because it’s often a relatively stressful time, right in the middle of the party and vacation season.
Don’t set yourself up for failure this year by vowing to make huge changes that will be hard to keep. Instead follow these seven steps for successfully making a new year’s resolution you can stick to for good.
1. Just pick one thing
If you want to change your life or your lifestyle don’t try to change the whole thing at once. It won’t work. Instead pick one area of your life to change to begin with.
Make it something concrete so you know exactly what change you’re planning to make. If you’re successful with the first change you can go ahead and make another change after a month or so. By making small changes one after the other, you still have the chance to be a whole new you at the end of the year and it’s a much more realistic way of doing it.
Don’t pick a New Year’s resolution that’s bound to fail either, like running a marathon if you’re 40lbs overweight and get out of breath walking upstairs. If that’s the case resolve to walk every day. When you’ve got that habit down pat you can graduate to running in short bursts, constant running by March or April and a marathon at the end of the year. What’s the one habit you most want to change?
2. Plan ahead
To ensure success you need to research the change you’re making and plan ahead so you have the resources available when you need them. Here are a few things you should do to prepare and get all the systems in place ready to make your change.
Read up on it – Go to the library and get books on the subject. Whether it’s quitting smoking, taking up running or yoga or becoming vegan there are books to help you prepare for it. Or use the Internet. If you do enough research you should even be looking forward to making the change.
Plan for success – Get everything ready so things will run smoothly. If you’re taking up running make sure you have the trainers, clothes, hat, glasses, ipod loaded with energetic sounds at the ready. Then there can be no excuses.
3. Anticipate problems
There will be problems so make a list of what they’ll be. If you think about it, you’ll be able to anticipate problems at certain times of the day, with specific people or in special situations. Once you’ve identified the times that will probably be hard work out ways to cope with them when they inevitably crop up.
4. Pick a start date
You don’t have to make these changes on New Year’s Day. That’s the conventional wisdom, but if you truly want to make changes then pick a day when you know you’ll be well-rested, enthusiastic and surrounded by positive people. I’ll be waiting until my kids go back to school in February.
Sometimes picking a date doesn’t work. It’s better to wait until your whole mind and body are fully ready to take on the challenge. You’ll know when it is when the time comes.
5. Go for it
On the big day go for it 100%. Make a commitment and write it down on a card. You just need one short phrase you can carry in your wallet. Or keep it in your car, by your bed and on your bathroom mirror too for an extra dose of positive reinforcement.
Your commitment card will say something like:
- I enjoy a clean, smoke-free life.
- I stay calm and in control even under times of stress.
- I’m committed to learning how to run my own business.
- I meditate daily.
6. Accept failure
If you do fail and sneak a cigarette, miss a walk or shout at the kids one morning don’t hate yourself for it. Make a note of the triggers that caused this set back and vow to learn a lesson from them.
If you know that alcohol makes you crave cigarettes and oversleep the next day cut back on it. If you know the morning rush before school makes you shout then get up earlier or prepare things the night before to make it easier on you.
Perseverance is the key to success. Try again, keep trying and you will succeed.
7. Plan rewards
Small rewards are great encouragement to keep you going during the hardest first days. After that you can probably reward yourself once a week with a magazine, a long-distance call to a supportive friend, a siesta, a trip to the movies or whatever makes you tick.
Later you can change the rewards to monthly and then at the end of the year you can pick an anniversary reward. Something that you’ll look forward to. You deserve it and you’ll have earned it.
Whatever your plans and goals are for this year, I’d do wish you luck with them but remember, it’s your life and you make your own luck.
Decide what you want to do this year, plan how to get it and go for it. I’ll definitely be cheering you on.
Are you planning to make a New Year’s resolution? What is it and is it something you’ve tried to do before or something new?
