From your description it doesn't really sound like any malware or rogue browser web site.
What does your Device Manager say?
I'm not a technical expert but that Hardware Instalment sounds like a problem with a driver or hardware component. What can you tell us about this system?
Do you have SATA hard drives with a SATA Controller?
Are there any exclamation marks against any devices in the Device Manager?
Also, look at the Event Viewer and see if any errors are logged there under System.
Do you have all your personal files backed up? If not, I would make a start on that now.

I am running both a W7 and an XP PC. The problem is with the XP ONLY. I have AVG Security. My screens assure me that all components are working. I also have a Windows firewall.
However, every 10 or so minutes whatever I am doing (including composing this post) I am interrupted with a small window headed Hardware Installment. Below that is this message: The software you are installing ... non-Plug and Play Drivers ... have not passed Windows Logo Testing. Then there's some other text and lastly two buttons: Continue or Stop.
I AM NOT in the process of installing either hardware or software. Three months ago I switched from ATT to Comcast so I switched routers but it is only recently that these messages started.
I have run both Malwarebytes and AVG's PC Update but they found nothing. That didn't surprise me because it appears there is a rogue computer out in the great beyond which will try this as long as I have this PC plugged in.
Any help will be greatly appreciated. Thanks!
