I had that about a month ago. First you need to use Windows Restore.
Then turn on your windows security esentials (make sure it’s updated) that comes free with Windows and do a FULL scan (takes awhile) then set it to rescan each night while you are sleeping.
I also completely deleted the Adobe directory with flash ect where the virus is usually located and downloaded a fresh updated version of what I use regularly (flash, reader, ect) directly from Adobe.
That did the trick for me.
restoring would work for a day or two ... but then I’d just get it again. Restore + full scan + deleting the entire Adobe directory, finally fixed it for good.
Thanks, TexasFreeper. Just prior to this I was getting unusually (to me) frequent Adobe updates. I will check that - and hope it doesn’t come back.
