After reading your column about updating Windows 7 (see tinyurl.com/zzhdlyf), I typed your tinyurl address into my browser and got strange results. A repeating audio warning said I had a virus and spyware infection, and that I should call the number on the screen (855-257-9669) before the PC became disabled. I restarted the PC and got the same warning. I then ran Microsoft’s Malicious Software Removal Tool (find it at tinyurl.com/z85al7o), which found nothing amiss. Finally, I called the number on the screen and played along while a man urged me to give him remote access to my PC, then hung up. Was this situation caused by your tinyurl? — Chuck Wilkinson, Eau Claire, Wis.

No. While I’m glad you realized the man on the phone was running a scam, this wasn’t a chain reaction caused by you typing my tinyurl into your browser. It was caused by a malicious program on your PC that is still active and needs to be removed.
