To remove Antispyware Soft, first you have to reenable internet connection first. To do so:
1. Reboot into safe mode with networking.
2. Launch your internet explorer and make sure your internet connection does not uses proxy server. Do so in other browsers as well
3. Download Spyware Doctor using this link (it should not be blocked by Antispyware Soft). Run and perform full scan.
If it fails, try blocking Antispyware Soft manually.
The best way to do so is start task manager (or, for example, process explorer) and stop all Antispyware Soft processes. The processes typically end in tssd.exe.
Afterwards, I would recommend doing full scan with Spyware Doctor or Malwarebytes anti-malware. It is critical to have a security suite that provides real time protection against such infections like this.
