Have I acquired the klez virus?

[MTOW]

I run Win 2000 and OE6. Yesterday I got two emails, both from the same address in Japan, advising me that Lotus Notes had detected that I had sent two individuals emails containing the KLEZ virus. Neither of the two individuals are in my address book, and both are also in Japan.

I run the free version of AVG6 antivirus, and the latest update available for that is 21 Aug. It doesn't find any viruses on my system. I've logged onto Symantec and downloaded both their fixklez tool and done a complete on-line scan - neither found any visuses.

However, if I go Start/Search/Files and Folders and write "klez" in the "containing text" field, every one of my directories in Outlook Express comes up as containing the offending word.

Question: do I have a new version of klez, or it it normal to find this word in every directory of OE?

Thanks in advance.
