I have seen some threads on this in the past, but this is a new issue.
Since about last Sunday my Mcafee Enterprise 8.0i has been deleting lsclient.exe as a generic downloader.x (Trojan).
This has happened to lsclient.exe I had from the 3.2 install, and the new 3.5 beta.
I presume from the threads that this is a false positive, but is there a version of lsclient that is not detected in this way ?
