Deleting this file is essential if you see it running after you open Internet Explorer.

I have SBC/Yahoo DSL which includes a large collection of files and programs

All I know is that my computer starts running at 100%CPU from this thing. I end the process and everything is fine and I am still on yahoo with no interruptions which makes me wonder if it really is yahoo. If it was, wouldn't it close the window?

You will find that yahoo VERY often hides its applications, such as this one so that users cannot uninstall them, that alone tells me that Yahoo products are spyware.

just installed Yahoo DSL and ZoneAlarm didn't know what ycommon was

I know little about this file. But, when I start my BT! Yahoo browser and nothing happens, stopping this process will make the browser open immediately. (Before I would have to restart the computer.)

my computer also runs at 100% when it runs I have not had any problems after I erased it with counterspy

i think it is a worm that yahoo put in

It appeared on my PC just one week before a serious infection with Sypware Protect 2009 manifested itself. Its associated prefetch file on the WINDOWS Prefetch folder cannot be moved, copied, and resistes deletion or even examination of its contents withe the Windows Notepad even with the computer running in Safe Mode and even with full Administrator privileges and even by using the DOS window, which should not be for prefetch files since these files are supposed to be erasable from the Prefetch folder
