As if scareware (fake antivirus software) via legitimate news sites wasn’t bad enough, now we’re getting a veritable swarm of malware (virus-like stuff you don’t want) via ad services sold to legitimate web sites by Google and Yahoo, among others.
The ad services, including DoubleClick, FastClick and ValueClick, offer infected ads that use malicious PDF files to inflict viruses via bugs in older versions of Acrobat Reader. You don’t even have to click on anything, merely visit a page with an infected ad. All you see is a window opening and closing as the PDF is launched. Remember, Google, Yahoo and the infected web sites are not going to protect you from this stuff. Your only option is to protect yourself.
Your best protections are using strong security measures and keeping your Adobe Reader (aka Acrobat) up to date. Meaning, if you’re not using the current version, 9.1.3 (and I know many of you are still on version 7 and earlier), you want to RUN not walk to Adobe’s site to download the latest version.
Installing Adobe Reader is similar to installing Flash. You’ll have to install Adobe’s Download Manager if you haven’t already, then download and install the Reader software. I’ve put the links for Acrobat Reader and Flash Player in the right-hand sidebar under Help For PC Users and Help For Mac Users.

More reports are coming in of scareware coming from major news sites including The New York Times and the Philadelphia Inquirer.
As I mentioned in my previous alert about scareware via Newsweek, it’s important to note that these scams can happen anywhere, anytime, even on the most reliable of sites. Please be careful, and bear in mind my recommendations on how to protect yourself from scareware.

Apple has released the first update for Snow Leopard, Mac OS X 10.6.1, due to erroneously including an old and vulnerable version of Flash in the original release. This update also includes a few additional fixes.
Even if you’re not running Snow Leopard yet, you’ll want to use Software Updates under the Apple menu to get your copy of the latest Security Updates for Mac OS X 10.4.11 and 10.5.8.
This article caught my attention recently, concerning a scareware scam that is being distributed via Newsweek’s web site. I mention this one in particular because it’s an example of how bad links sometimes come from good sites.
Scareware is when you receive a popup that insists there’s something wrong with your computer. It’s a scam to try to get you to click on a link, thus infecting your computer with viruses and possibly also ripping off your credit card. Don’t expect your antivirus software to catch this stuff, it often sneaks through. I strongly encourage you to protect yourself through a combination of good computer security, free web site ratings software like McAfee SiteAdvisor or LinkExtend for Firefox, and plain old common sense.
Here are some of my previous articles which may help you out in this situation:

I thought I’d take a moment to explain to my regular readers how I’m using Twitter in relation to Tech Tips.
Most of you already know that I offer Tech Tips in two formats. There is the email version, where I publish my newsletter on the 15th of the month and also provide notification of new blog entries as they become available. My blog is where I add tidbits pertinent to the computer needs of small businesses and consumers.
Some of you may not know that I am a freelance writer as well as a computer consultant. To that end, my Twitter account contains a little of both. In addition to providing computer news and links to relevant articles, I will also be including updates about freelancing, writing, Web 2.0 and my primary genres, science fiction and fantasy.
If you’re interested, come join me on Twitter. If you prefer your Tech Tips straight up, you may wish to stick with my blog and email list. Don’t forget that email subscribers receive bonus product reviews and other information. As always it’s completely FREE, and your email address will never be sold to third parties. You can also find my Twitter updates (tweets) in the upper right-hand corner of the Tech Tips blog.
And if you’re curious about Twitter but not sure how to start, come to my Social Networking: Marketing Your Business Online class on September 24th. You’re always welcome to follow me on Twitter to get your feet wet. I promise to give you a stress-free introduction to the world of social networking.
To update Wednesday’s post, Microsoft has released a new Office 2008 For Mac update which fixes a glitch that prevented users from opening some Office 2007 For Windows (.docx, .xlsx, .pptx) documents. The new update is version 12.2.1 and can be obtained here.
Two major Macintosh updates of note. The first is that Apple has released the latest update for Leopard, Mac OS X 10.5.8, along with a slew of security updates for Leopard and other versions of the Mac OS. As always it’s a good idea to back up your system before applying these updates. You will find them via Software Updates in your Apple Menu.
On a similar note, Microsoft has released an update for Office 2008 for Mac, and with this one I have to urge caution. Service Pack 2 (version 12.2.0) breaks compatibility with Word 2007 for Windows (.docx) files. You’ll find the advisory and workarounds here. If you require the ability to open .docx files I recommend you hold off on this update until the problems are fixed.
A recent update for the Windows-based AVG antivirus program surprised users when it mistakenly identified several components of iTunes as a malware trojan called Small.BOG. This is called a false positive, when security software quarantines legitimate software.
If you run into this problem, the fix is to update AVG, then update iTunes. This technical bulletin from AVG provides more details.

Microsoft is releasing a pair of out-of-sequence security patches tomorrow, to fix vulnerabilities in Internet Explorer and Visual Studio. It’s unusual for Microsoft to stray from their regular Patch Tuesday cycle (the second Tuesday of the month). While the Visual Studio patch will affect a small percentage of computers, the Internet Explorer patch applies to any computer running Windows.
To make sure you get these updates, either turn Automatic Updates on (bearing in mind the pros and cons of doing so) or visit update.microsoft.com to check for these latest patches.
Software patches (also called updates) are fixes for bugs that could allow malicious software to enter your computer. By staying current on these patches, you improve your computer’s defense.

There’s a lot of talk in the news about the recent cyber attacks on U.S. and South Korean servers. Computers in both countries were disrupted through what are called “denial of service” attacks, when hackers use infected computers called zombies to slow or crash target servers. Zombie computers are often owned by small businesses or consumers who are completely unaware they are infected. I’ve mentioned zombie computers before (here and here) but it’s important to reiterate how you can protect yourself and others.
Your best protection is prevention. Be sure to run a reliable antivirus program like those below (beware of the fakes!) as well as anti-spyware software. Security suites offer a way to combine those protections with a firewall to block unwanted network probes. Regular software updates are also key to keeping your computer protected. You can learn more about these techniques in my article on cybercrime. I am teaching a class on How To Protect Yourself From Cybercrime on Monday July 20th from 9:30am-11:30am in Cary, Illinois (click here for more details and registration information).
