I get this file on each/every PC I install a logitech product on.. I have been using there equipment for yrs now & have NEVER had a problem with this file being present and targeted as the culprit
File from Backweb called "IadHide.dll" from company called Backweb found in my "Temp Internet Files" and could not be deleted. No uninstall feature. I found it embedded in the Hewlett Packard Updater File Folder. Had to delete entire folder to remove the "IadHide.dll" scum. Blocked HP access to my computer to prevent reinstall. They claim it is necessary for updates. Call it what you will, Backweb had developed a VERY NASTY PROGRAM. Prevents audio cd burning and shuts down MS Firewall!

It's suspicious! Mine is in a Temp folder(subdirectory) of a hidden folder and is 'access denied' to me even when running as administrator in a command prompt window under Windows XP (SP2). If all they are doing is checking for updates at Logitech, then they shouldn't mind if I disable them from doing that. I can do that at my convenience. I tired of all these TSR's trying to determine update status from home base. It slows down my startup and makes me feel like I have no control nor authority over my own system. It's even worse if I have the net unavailable to them.

Cannot delete from my local settings. Has blocked me from deleting all the temp internet files. Have had to resort to downgrading to IE6 to solve the problem.
It flashes up on my screen and asks to send a report or not send a report. Have to click a number of times before it will disappear. So annoying.
