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..
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
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
