trojan horse!

Symantec has a good description of how to remove this. Follow the steps they recommend! Boot in Safemode as Administrator, remove regentries, remove w\services.exe, w\s32\fservice.exe, w\s32\sservice.exe. Reboot again in Safemode, scan with antivirus, reboot with your normal user, SCAN AGAIN!, the files are 'owned' by your normal user account, this is not written somewhere, but I experienced it...

prorat really works as a hacking device.. but it create so many trojans.... this sucks! if you simply delete the file... it will create a boost up error on start up... really sucks!
is a prorat trojan,can't remove it with antivirus,you can remove with a trojan remover...or with prorat (i think...) be carefull while you have it...if you can't remove it just format your c: drive and reinstall windows or you might lose all data ,the prorat user can FORMAT your local drives so be carefull! the user of prorat can also play with yor pc (like eject ypur cd-rom, making yor windows start butto to dissapear and stuff...)good luck!
Right it can be taken off by Prorat.exe if the person who hackt you Removes the server from your p.c it will be deleted :) dont ask why i know this because i ant gonna tell ya

Best practices for resolving fservice issues

A clean and tidy computer is the key requirement for avoiding problems with fservice. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the fservice.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
