System Cleaner / Took over my desktop!
Out of nowhere, i get this new desk top in dark blue with big red letters telling me my computer was infected with spyware. They misspelled "YOU'RRE infected". I tried to reset my desktop, but it kept coming back. In the lower right of my screen was a little shield that would pop up a warning to get this software. Then another pop up would appear telling me "Security-monitor warning/Trojan SPM/LX.
I contacted my virus/spyware provider, we couldn't get rid of it. I eventually had to restore my computer to a date previous to the problem, it seems to be OK now.
Hope this helped somebody out...
