I suffered from system unstability due to some growing Outlook Express message.. some trashes like these with *.eml and *.nws keep occuping my HD space and causing mt puters to warn me that space is very milited to run any further action. I tried to scan the HD with Norton with no avail... some are in Poser ( but I don't think they are virus from the program ) . all the eml and nws use the filenames I used, and I have no way to delete them all as everytime I delete the eml and nws, they keep growing again. I have to give up. also a file call riched20.dll in win98 and win200 systems are strange as it claims to have eml extension. Are my puters infected by virus unknown to Norton ? I can't delete my Poser 4 ( 4GB ) as it contains some valued files from r'osity. Please enlighten me how to del with such dilemma. Merci.
