1/30/2007 TomTom is BadBad

A couple of viruses hitched a ride with TomTom Go 910 satellite navigation devices. TomTom says it was a "small number" of devices manufactured during September-November 2006. The devices have hard drives, and the win32.Perlovga.A Trojan and TR/Drop.Small.qp malware managed to sneak on. These are Windows malware, and while the Go 910 are Linux devices, you can connect them to your computer for backup and updates. TomTom says that antivirus software will work on the infected units.

0XC004D401 or 0x80080250

1/28/2007 Intuit QuickBooks Problems with Windows Vista

It appears that Intuit QuickBooks 2006 is not compatible with Windows Vista. In this case, the blame appears to lie with Intuit, for QuickBooks uses some techniques in communicating via the Registry that violate Windows XP standards, much less the newer Vista. David Berlind covers this in a number of posts at and earlier.

1/26/2007 Yet Another Word Zero-Day Bug

The Symantec Security blog is reporting yet another Microsoft Word zero-day vulnerability. (This would be the fourth that's currently unpatched, if you are keeping score at home.)

1/25/2007 Windows Vista Versus Your Startup List

The Windows Defender program may not like some of the items on the startup list on a Windows Vista computer. While your computer booting up, you may see a message over on the far right of your taskbar that says:
Windows has blocked some startup programs. Windows blocks programs that require permission to run when Windows starts. Click to view blocked programs.
Clicking will show you what's been blocked. (Chances are, they are older pre-Vista applications, especially if this is a computer you upgraded to Vista.) See for various things you can do as a workaround.

1/22/2007 Microsoft Re-Releases Security Bulletin

1/17/2007 The Zombies are After Symantec

It's not quite Night of the Living Dead, but an army of remotely controlled zombie computers are targeting computers running old versions of Symantec Client Security and Symantec AntiVirus Corporate Edition. You can read about the details at Note that Symantec's consumer software, Norton Antivirus and Norton Internet Security, are not affected. Symantec actually patched the hole being used on 5/25/2006, so victims have had ample time to apply the fix. The original Symantec fix is at

1/16/2007 IE 7 Brings A Non-working Icon

Upgrade to Internet Explorer 7 on a Windows XP Service Pack 2 computer, and you may get a new icon on your desktop that says "Restore My Active Desktop". Click on it, and nothing will happen.

1/15/2007 Upgrading an Embedded Excel Chart is Buggy

If you upgrade a Microsoft Excel 2003 chart to Excel 2007, and the chart is embedded in a Microsoft PowerPoint 2003 presentation, data labels in the chart may get moved. According to Microsoft, this may make the chart difficult to read in PowerPoint. There is no workaround or fix yet.

1/13/2006 Bugs in Apple UFS Filesystem via DMG Files

The Month of Apple Bugs (MOAB) project has come up with a series of bugs in the UFS filesystem that can be triggered via DMG files (disk image files). At least one of the bugs can be remotely exploitable via Safari if the "opening safe files after downloading" option is turned on.

1/11/2007 Word 2007 Doesn't Like Org Chart Editing

Try to edit an organization chart from within Microsoft Word 2007 by double-clicking the chart, and you may get this error message:
The program used to create this object is OrgPlusWOPX. That program is not installed on your computer. To edit this object, you must install a program that can open the object.
Microsoft has three suggested workarounds. First, try editing it again; they seem to think it may work the second time; if that doesn't work, right click the chart and select Edit. If that doesn't work, then you'll need to install the Organization Chart Add-in. See how to do this at

1/10/2007 Adobe Patches Acrobat 7.0.8 Holes

12/31/2006 Redesign on the Fly

We are going to start 2007 with a redesign of the BugBlog website as well as From a design standpoint, it is only a subtle redesign, but in terms of the HTML behind the scenes, there are quite a few changes - dropping the old JavaScript powered rollover navigation buttons for CSS-based navigation controls, and using CSS layout and positioning instead of the old table-based design. Because I'm overlaying the new pages and graphics on top of the old, there's certainly a chance that something will get mangled. If you find a bug in the BugBlog, please let me know. All the old pages won't be converted -- but everything else going forward should be XHTML compliant.

12/30/2006 Reports of Some Gmail Problems

Techcrunch reports on an issue where a number of people, who all appear to be Mozilla Firefox 2.0 users, reported a mass deletion of their Gmail emails, while they were logged in.

Just goes to show that you should back up your Gmail, err... never mind.
