Avast detected but failed to stop HKEY_LOCAL_MACHINE\SOFTWARE\Micro Data:c\window
" " " " " " " system32\

My Anti Melware has detected in scan and prompted me to remove and reboot, but when i reboot, it’s still there. What can i do without totaly removing windows and re loading?

Avast will not let it conect to server,but it keeps trying to which crashes any program i’m working in at the time.

Have you tried a boot time scan with Avast ? What anti malware program did you use ?
You could try MBAM, SAS,and post a HijackThis log
