So im running Windows 7 64bit Home Premium and mostly playing games and such things on Steam and Rockstar Social Club (GTA)

I was doing a pingplotter test for my ISP along with TCPoptimizer which i usually do on all my computers without problem. 
After tcpoptimizer ran i needed to restart the pc and in the same moment Firefox were automatically closed by windows

After that these issues appeared. First mozilla firefox icon were gone so i ran a Icon cache rebuild script and that fixed the issue on that part.. 

ie4uinit.exe -ClearIconCache
taskkill /IM explorer.exe /F 
del "%iconcache%" /A

1.  Firefox were not fast....   could take 2 minutes before google appeared when Google Chrome loads google.se in 1second  (100/10) connection 
2. Firefox.exe   does not close when the browser is exited. The process remains in taskmgr 
3. Whenever i close firefox and need to start it again i first haft to delete the firefox.exe instance in taskmgr....  wtf 

I tried: 
Clearing CCleaner temp/prefetch and uninstallting Firefox and all related files 
Deleted all firefox related files in both folders, %appdata%  and Regedit  without any effect 

because of this i strongly think ive been infected somehow but i ran Malwarebytes, Hitman Pro and they came up empty so what can cause this strange behavior suddenly
