yes this is a virus. I had it I run win XP pro. to remove it in xp any way. do a search for the files one at a time. x.EML and so on. once the scan stops select all in edit do not use the mouse click and drag or you activate them. after selecting got to edit again and deleat. the rich20.dll is the sorce of the viri. you have to deleat them all. make sure all downloads to your puter is set to question as all the files dl more to your system. after you have deleated all of them and emptied the trash. reboot with your net connection disabled first then disconected. if you missed some of them you will get a networking error. bypass this and search again deleating all you find. next go to system volume info deleat all but the most recent one. search when nothing found reboot then to vol info again dleat all but the latest one. last but not least. save your config after your reboot with out net conected are error free. nother file to look for is desktop.ini there should only be one in the windows dir. this virus creat thousands of them and every dir you enter with them in it it redls the virus and you start all over again :/ I wish you luck getting rid of this, it took my tec 13 hrs to totaly clean the system of it. but far beter than a week or two to reinstall exverything after a reformat. hope this helps laters Vel
