AVG Antivirus Mistakenly Marks iTunes As Malware
Monday, July 27, 2009
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.

Emergency Microsoft Patches Issued Tomorrow
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.

Most Dangerous Web Search Terms
Tuesday, July 14, 2009
A recent McAfee study (pdf) reveals that searching for certain keywords carries a greater risk of being infected with malware.
McAfee found maximum risks associated with the word, not surprisingly, "free". Studying the U.S. in particular, words associated with celebrities or song lyrics demonstrate how malware gloms onto recent headlines and trends. "Screensavers", "free music downloads" and "free ringtones" remain popular ways to lure you into clicking malicious links. And the keywords "search engine marketing" or "search engine optimization" have become increasingly linked to sites that deliver malware or scareware antivirus scams. In short, just because a link comes up when you search for a particular keyword doesn't mean that link is where you want to go.
I recommend free programs like McAfee SiteAdvisor or the even better LinkExtend for Firefox as plug-ins for your Web browser. These programs rank search results to give you a better idea of whether or not the links are malicious. But your safest bet is to type Web addresses manually, for example going directly to www.snopes.com instead of searching for it by keyword.

Protect Yourself From Zombie Computers
Thursday, July 9, 2009
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).
Antivirus software for PCs:
- Trend Micro
- AVG (free)
- Avast (free)
- McAfee
- (But not Norton; here's why.)
- Malwarebytes (free)
- AdAware (free)
- Spybot (free)

FTC Slaps Fake "Win Antivirus" Scammers On Wrist
Tuesday, June 30, 2009
The FTC has agreed to settle with some of the scammers responsible for the repulsive "Win Antivirus" scam, in a decision that's effectively a slap on the wrist.
I doubt this will result in any kind of serious setback for the fake antivirus software industry. $116,000 is chump change for criminals who charge consumers $50 and up for these bogus products, which are known by various names including Win Antivirus, XP Antivirus, WinFixer, DriveCleaner, and ErrorSafe. Check out my previous entries here, here and here for more details on how insidious these programs can be.
There is more money still being made out there at your expense, so be sure the programs you're using are the real deal. I hope the FTC will continue to pursue and prosecute the miscreants responsible for such scams.

Is Microsoft Security Essentials Worthwhile?
Tuesday, June 23, 2009
Microsoft has released a beta (test) version of its upcoming Security Essentials program, which is scheduled to be rolled out to consumers in September. Microsoft Security Essentials is, essentially, a stripped-down version of the ill-fated OneCare. The question is, will it do a better job of helping consumers protect their computers from viruses and spyware?
My guess is, not really. Sure it's free, but so are other programs with better reputations for removing the gunk from your computer. Even so, most free programs do not offer the complete protection of a full-fledged security suite. My fear is that the presence of Microsoft Security Essentials may lure some consumers into complacency, with the impression that their computers are adequately protected when they're not. I already see this with programs like Windows Defender and the monthly Microsoft Malicious Software Removal Tool, neither of which are suitable replacements for real security software.
Of additional concern, and the reason I'm mentioning this now even though the software's still beta, is that scammers will undoubtedly glom onto this just as they grab any popular headline in their attempts to con you into fake antivirus software. Just because something claims to be "that new software from Microsoft," don't believe it unless you're downloading from a bona fide site.

Does Conficker Infect Macs?
Tuesday, March 31, 2009
Another question about Conficker I've been asked a lot lately. Short answer: no.
More specifically, not unless you are running Windows on your Mac (through Apple Boot Camp or a virtual environment like Parallels). However, I do recommend antivirus software for Macs.

Conficker Virus April 1 Deadline
Monday, March 30, 2009
Lots of people have asked me about the Conficker virus and its April 1, 2009 deadline. The short version is, make sure you have your latest antivirus updates and Microsoft patches.
Conficker aka Downadup has been around for months (you can find my other entries about it here, here and here). Like other viruses it works by installing a core piece of itself, then downloading so-called "payloads" that enable other abilities. Hackers test variants of the virus by unleashing them on an unwitting world, in this case Conficker A, Conficker B, and Conficker C, the latest and most aggressive. On April 1st, researchers predict Conficker C will download its payload, this one possibly with far-reaching consequences. But it's hard to tell if this is media hype or real danger.
Your best protection is prevention. Even if you think you're okay, a scan with a Conficker detection tool wouldn't be amiss. And be sure to subscribe to the email version of Tech Tips for the latest computer news.
ADDENDUM: Scammers are poisoning search results, so if you try to do a web search for instructions to remove Conficker you may wind up at malicious web sites. Be sure to obtain removal tools only from legitimate sites like Microsoft's. When in doubt, type the address manually into your address bar instead of clicking on a link.

Antivirus 2010: A New Low In Fake Antivirus
Tuesday, February 24, 2009
From the malcontents who bring us fake antivirus software comes "Antivirus 2010," a Windows scam so sneaky it puts its predecessors to shame. It looks horrifyingly realistic (see screenshots) and it goes all-out in pretending to be legit:
- Mimics Windows' own Security Center with warnings to register the fake software
- Mimics Internet Explorer errors to imply you need the fake software before you can visit web sites
- Mimics Windows startup screens to imply you can't start your computer without registering the fake software
- Creates phony errors in Windows to imply your computer is unusable without the fake software
- Pretends to find and fix problems that aren't present on your computer
- Offers a realistic-looking web site for download and registration
- Redirects your machine to fake web sites with fake reviews extolling the fake software!

Valentine Viruses And Phony Parking Tickets
Friday, February 13, 2009
Every holiday we get a spate of viruses, and every holiday I feel compelled to warn you about fake electronic greeting cards. Trust me, virus writers will do just about anything to get you to click on their infectious links, so ignore those pretty Valentines.
In other news, a recent ruse demonstrates how computer security bleeds into everyday life. In Grand Forks, North Dakota, miscreants went so far as to put phony parking tickets on cars. The link that purportedly takes the victim to a police web site is actually infused with malware. This is an example of social engineering, when hackers use real-world tricks to achieve digital domination. Another is the ever-popular leaving of USB flash drives in public places. Most people don't hesitate to try them on their computers, at which point hidden viruses go to work bypassing firewalls and introducing back doors into networks.
