I bought Logitech's QuickCam Messenger Webcam to communicate with family in England. After I loaded the product's driver, it corrupted my system: My e-mail and Web browser would randomly stop working. My ISP, EarthLink, said the problem was likely an ad-serving program that was included with Logitech's driver. I eventually fixed my PC and called Logitech about the issue. The company said it uses a technology called BackWeb in its software and can't change how BackWeb does certain things. But Logitech is allowing BackWeb to cause problems on people's PCs.

On Your Side responds: Logitech uses BackWeb's technology in software called Logitech Desktop Messenger to send QuickCam (and other Logitech hardware) users pop-up alerts about software upgrades and new Logitech products, services, and special offers. The company says it does not collect personal information. To target messages, however, it collects data about system configuration and about which Logitech products are connected to the PC.
The anti-spyware utility Spybot Search & Destroy identifies Logitech Desktop Messenger as spyware. But using Spybot to remove LDM may cause problems.
To completely remove LDM, use the Windows Add/Remove program. To prevent LDM from sending you messages, go to Start, Programs, Logitech and select Desktop Messenger. Uncheck the two notifications check boxes and click Done.
