Yup, I got the same about a week ago.It was picked up by Unthreat but it was of no concern due to it being in the temp files which were sandboxed anyway.
Not a good ploy for malware to pose as a test virus as most AV`s will pick up on it.Maybe EICAR somehow got out in the wild and now is whirling around as a driveby ?
Had to get rid of Unthreat as it kept reverting to an expired trial version.Shady tactics,to be expected.
