Annoying Problems & Fixes 
These are a few that I personally struggled with.  They are tough to remove. 

Actulice  
Random messages: "nomodf" "actulice" "funk"
Search and Remove files:
_850c.exe
playd.exe
mgrprxyq.exe

680180.net  
www.680180.net pop up when offline and online
 Delete the following files to resolve the popup issues:
%Windir%\System32\ADStartUP.exe
%Windir%\System32\AdUpdater.exe
%Windir%\System32\adupdmanager.xml
%Windir%\System32\data.xml
%Windir%\System32\IEEnhancer.dll
After deleting these files from your system you will need to 
delete a registry entry:
Click the "Start" button on the taskbar
Click "Run..."
Type "regedit" and click the "OK" button
Click the "Start" button on the taskbar
Open “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Run“
Right-click "Adstartup" and click "Delete"

Flashlightsearch.com  
Re-directs Browser to Flashlightsearch.com
It installs a program called "TV media". Go to Add/Remove programs and uninstall it. However, it is actually still on the drive. 
Reboot your computer to safe mode and delete the "TV media" folder on your hard drive. Run RegEdit and delete the entries to "tv media".
