Thanks for the misinformation, Disney

In one of its throwaway kid’s sitcoms, Disney insinuates that open source software contains spyware and using it is a ‘rookie mistake’.

Open source software rarely contains viruses or spyware. Since it’s open for examination, changes to the code that have any funny business in them tend to be rejected. For that matter, code with unintended bad consequences tends to either be rejected, or quickly changed.

Is the Windows firewall safe enough?

Is the Windows Firewall safe enough? I wish more people would ask that question rather than make assumptions.

I wish I had a nickel for every time I’ve heard an unsubstantiated statement like “Windows firewall is junk.” I went looking, and the best I could find was this, an editorial that said it doesn’t do enough to address outbound connections, particularly on a program-by-program basis.

OK, point taken. But “enough” is a moving target.

Things I wish everyone knew about home computer security

I’m a security professional by trade, with two certifications. I’m not responsible for defending your computer networks, but I want your networks to be secure. There’s a really simple reason for that. If your computer and your network is secure, then it isn’t attacking mine. Or anyone else’s.

Several fellow subscribers to a train-related interest group that I like got hacked recently, and have been sending out spam messages. They’ve received a lot of advice in the hours since. Some of it has been good, and some not as good. So I tried to think of some things that people could do in about 30 minutes to keep the crooks at bay.

Incidentally, the computer crooks won’t be going away. Computer crime happens because the criminals can make more money doing that than doing something legal. The only way to make it stop is to make it too hard, so that getting a real job becomes more profitable. You won’t solve that problem in 30 minutes, but if we all take that single step down that road, we’ll make the world that much safer. So, with that, let’s roll up our sleeves. Read more

End of the innocence for Mac security

Antivirus vendor Kapersky has identified a new trojan horse targetting Macintoshes.  It spreads a botnet based somewhere in China via an infected Microsoft Word document, typically sent as an e-mail attachment.

The spin is that if you don’t use Word on your Mac, you’re safe. That’s true–this week. But going forward, it’s going to take more than that. Read more

What I would do to fix Dr. A’s computer

I left my conversation with Dr. A nearly convinced he doesn’t really need a new computer. The local store is pitching him a new $700 Dell Inspiron with a 1 TB hard drive and 6 GB of RAM and a 17-inch screen. But he could upgrade to a 1 TB hard drive for less than $125. If he doesn’t want to switch to Windows 7, his current Windows XP Professional will only use 4 GB of RAM anyway. Upgrading to 4 GB of RAM will cost less than $40. And looking at the new system, I don’t know that its CPU is all that much more powerful than what he already has.

To me, the clincher was this. I asked myself the question whether, if I were offered a machine exactly like his for $200 or $300, would I buy it. And it was an easy answer. I would.

I haven’t done a thorough analysis of the machine, but I’ve seen enough to have an idea what it needs. Much of it will seem familiar, if you’ve been reading me a long time.

Disadvantages of Windows 98 and 98SE

Many years ago, I wrote about the disadvantages of Windows 3.1 because I started noticing people searching for that. Now, I see people asking the same question about Windows 98. I spent 9 months of my life ripping Windows 98 apart and putting it back together again and writing about it, so I know it well.

As much of an improvement as Windows 98 was over Windows 3.1 and even Windows 95, it, too, is feeling the effects of time. Windows 98SE was the best of the Windows 9x series (better than its successor, Windows ME), but there are better things to run today.

How to clean viruses off other people’s systems safely

What should you do when someone hands you a computer, tells you they think it has a virus, and asks you to clean it?

Proceed carefully, that’s what. You don’t want to infect your other computers with whatever it has.

To get it gone safely and effectively, you really need two things: an antivirus live CD, and a spare router.

Speeding up a sluggish HP Mini 110

My mom’s HP Mini 110 Atom-based netbook (with the factory 16GB SSD) was hesitating, a lot. Frankly it was really frustrating to use–it would freeze up for minutes on end, for no good reason. It was so slow, calling it “sluggish” was being kind. But it’s fixed now. I did six five things to it. Here’s how to speed up an HP Mini 110.

Fix host hijacks or host file hijacks for free

Sometimes your antivirus will tell you that you have host hijacks or host file hijacks, but not elaborate on how to fix them. Some people charge way too much to fix them. Here’s how to fix host hijacks or host file hijacks for free.

A former classmate’s computer suddenly stopped letting him get to search engines. Aside from that, his computer appeared to be normal.

Fortunately he had some antivirus and antispyware software installed, so he was able to run it and get a relatively clean bill of health, but he still couldn’t use Google or Bing or Yahoo.

One of the pieces of software he ran mentioned a host hijack or hosts file hijack, but didn’t offer to clean it up without ponying up some serious bucks.

That was enough to tell me how to clean it up though. You don’t have to buy anything. Read more
