Thanks to Andre and Andy for Apropos:

Try Ewido and Ccleaner , There is probably files in temp
folders as a backup incase you delete the main files and
using Ewido & Cceaner will clear these
download, install and update the free version of Ewido
trojan scanner:
http://www.ewido.net/en/download/
When installing, under "Additional Options"
uncheck "Install background guard" and "Install scan via
context menu".
From the main ewido screen, click on update in the left
menu, then click the Start update button.
After the update finishes (the status bar at the bottom
will display "Update successful").
Exit Ewido DO NOT SCAN yet
Please download CCleaner,
http://www.ccleaner.com/ccdownload.asp
Install it but do not run it yet.
Boot into safe mode:
Restart your computer and as soon as it starts booting up
again start tappin the F8 key.
A menu should come up where you will be given the option
to enter Safe Mode.
Run ewido, click on the Scanner button in the left menu,
then click on the Complete scan.
If ewido finds anything, it will pop up a notification.
You can select "Remove" and check the boxes "Perform
action with all infections" and "Create encrypted backup"
before clicking on OK.
When the scan finishes, there will be some options at the
bottom of the screen, click on "Save Report". This will
create a text file, save that to your desktop incase we
need it later
Run MS Antispy on a full scan and remove anything found
Run Ccleaner and press "Run Cleaner"
Reboot back to Normal mode.
Let us know if you need any more help with this
Here's a couple more options
Download symantecs removal tool
http://securityresponse.symantec.com/avcenter/FixAprop.exe
Save to desktop
Reboot into safe mode (Reboot and keep tapping F8)and run
the Symantec removal tool by double clicking FixAprop.exe
then use Ewido and Ccleaner
(Safe mode is important as products with real time
protection can prevent changes being made which may
interfere with the removal of malware)
Also check your add/remove screen(Start Menu>Control
Panel>Add/Remove Programs) for:
Apropos
AproposClient
AproposMedia
POP (People on Page)
And remove if found.
Regards Andy
Good luck
