Is this a virus?

[didocus]

The CPU usage of the PDC is 100% (very high Kernel Times).I found about 2000 files with name "mep***.tmp.exe" in "c:\\winnt". (*** replaces different numbers). The number of files with such name increases very fast. I suppose that is causing the high CPU utilization.
I run a check disk and I am running currently NAV check with the latest definitions.
Any ideas wiill be appreciated!!!

Yes, this is the W32.Nimda virus. NAV will need the latest defs which will be released tonight 8/18.
