Marie,
It might be
this. "The application spidentifier.exe, “Search Protect Identifier Stub by conduit” by Conduit has been detected as a potentially unwanted program by 7 anti-malware scanners. The program is a setup application that uses the NSIS (Nullsoft Scriptable Install System) installer. This file is typically bundled and installed by the program Open Downloader Manager by opendownloadmanager.com which is a potentially unwanted software program. The file belongs to the Conduit API platform, a uility that bundles and monitizes search toolbars and web browser extensions."
If so, it's not a virus, which is something anyway, but it is malware.
Do you have Open Download Manager on your computer?
If you do, start by getting rid of that.
Then if you have Malwarebytes, run it; if you don't, you can download a free version at
http://www.malwarebytes.org.It could be that when download manager or the game was installed, a default option which you have to UNcheck was that you wanted this 'spidentifier' to install.
Explain to your daughter that when she downloads something, she should be very careful not to agree to take things you may not want on your computer.
Good luck!
Gil.
