      While cleaning up my system I noticed that my c:\windows\temp had a 30MB file named wfv1.tmp in it. I tried to delete it, but the file is in use. I did a type wfc1.tmp and the first line is:
      McAfee AV-Engine internal file
      I am running engine 5300 and the file has been there since I updated. Is anyone else seeing this? 5200 didn't have a tmp file that I noticed.

          It's on all of our machines after the 5300 engine update. I'm not quite sure what it does, but it's there, and as you stated, it's a fairly large file..

          Hope this helps.

            I'm seeing it too. The number seems to be random; on one of my systems it is wfv5, one is wfv24, one is wfv717, while on another it is wfv4A6. All are about 32 mb but I've caught one to be reporting 0kb after seeing it as 32 mb earlier. The file normally cannot be deleted because it is in use. It appears to be created upon bootup but it does not get created when you boot into Safe Mode. The number appears to stay constant to the machine (that is, it doesn't change when you reboot). I can't open the file so had our webmaster take a look at it. He confirmed that McAfee is mentioned in the file's header.

                Thanks for the KB #s. I wish they went into a little more detail about how this actually works. Basically, it appears that 5300's better memory performance comes at a hard drive storage price. But considering the price of storage, that sounds like a fair trade-off to me.
