Disinfect Failed Two User\cookies Help Please!

I just updated my BD to the 2009 and did the full system scan and came up with two that BD could not or would not disinfect


Threat Name: Cookie.WindowsMedia


Object Name:


Documents and Settings\user\Cookies\user@windowsmedia[2].txt


Documents and Settings\user\Cookies\user@www.windowsmedia[1].txt


Are these something I need concern myself over?
