Posting this as a heads up to others who might get the same message.
While on the internet I suddenly got a flashing message on my task bar about AdobeFlashPlayer.exe requesting permission to continue.
I opened my User Account Control and saw the following message:
A program needs your permission to continue.
If you started this program, continue.
Adobe Flash Player
Adobe Systems Incorporated
Two options: Continue or Cancel
I looked in the specifed temp folder and the file wasn't there.
With my suspicions arouse I clicked Cancel.
In a moment the flashing notice on the task bar returned and continued to return each time I clicked Cancel.
A quick googling confirmed that this could be malware.
Malwarebytes found four items in that same temp folder:
Rootkit.0Access - File - xsnaomwrce.exe
Rootkit.0Access - Memory Process - xsnaomwrce.exe - 4456
Rootkit.0Access - File - msimg32.dll
Trojan.FakeAlert - File - o8GFGT8rE4gWoT.exe.tmp
During the Malwarebytes scan, MS Security Essentials detected a Trojan: Win32/FakeSysdef
All items were removed from my computer and when I rebooted the flashing notice did not come back.
So, if you find flashing notices on your task bar that come up suddenly, make sure you check them carefully before OKing them.
