I am suddenly receiving the following error message whenever I try to open things like Firefox, Google, Yahoo, and probably more that I haven’t tried yet. I am running Windows XP Home Edition and it is up to date, so far as I know. Computer is a Dell Dimension 3000 and has performed faithfully for at least the last three years. Any, the error message follows: [Exception… “Component returned failure code: 0x80570015 (NS\_ERROR\_XPC\_CI\_RETURNED\_FAILURE) [nsIJSCID.createInstance]” nsresult: “0x80570015 (NS\_ERROR\_XPC\_CI\_RETURNED\_FAILURE)” location: “JS frame :: chrome://searchshield/content/overlay.js :: InitSDK :: line 352” data: no] Please remember that I am far from being computer educated—I can use one so long as it works----if it doesn’t work, I’m dead in the water. Thanks for any inputs, advice, recommendations, criticisms, or what have you. Please don’t tell me to change operating systems. That only makes my head hurt. ---

The AVG extension causes this according to [this thread](http://support.mozilla.com/tiki-view_forum_thread.php?locale=tr&comments_parentId=215403&forumId=1). You can disabled it from Tools \> Addons and right-click on AVG and select disable. If that doesnt work then uninstall AVG. Once its working again you can reinstall it. ---

It could be _any_ addon or extension, not just AVG. Disable your extensions one by one until you find the culprit. To do this in Firefox, go to Tools \> Add-ons, click the one you want to disable and click the Disable button which appears. ---

My understanding is that “searchshield” an AVG technology. SO “chrome://searchshield” means AVG. ---

Thanks for the suggestions; it does appear to be add-on related. I disabled all my add-ons; the good part is that I don’t have that many. The good thing is that enabling them one at a time allowed Firefox to start and run trouble free. The bad thing is that when I enable AVG, I get the following information dialog: “TypeError: Components.classes[cid] is undefined.” Pressing the OKAY button in that dialog box allows the computer to start smoothly. BUT—at the moment, I have no anti-virus program; AVG doesn’t open. What now, please—I can’t stay on-line without an anti-virus program. ---

AVG or one of its core components is possible corrupted, it sounds like. I’d uninstall the current installation of AVG, download the latest build [here](http://free.avg.com/download-avg-anti-virus-free-edition), then re-install it. If you’re paranoid, you can go offline to do the re-install, but IMO it’s not necessary. Just don’t download anything else or click strange links. ---

Thank you so much. I don’t know how I would survive computer failures without you guys. ---

I apologize for crediting only Q.E.D. with the answer; I meant to include your response as well.
