Virus froze my computer, can't download any antivirus

computer is totally frozen up in regular mode. Been tring to download all sorts of maleware, antivirus ect.(in safe mode). Every attempt is blocked. Either it stops, or just won't left me even go to certain sites...such as malwarebytes .net. Some i can download, but then not be able to open and run, "spybot search and detroy".

Is there any way to fix without needing to download a CD from another computer? Will have to go to office if so,

Please download the current version of HijackThis from HERE

• Double click and run the installer.
  
• It will install to C:\Program Files\Trend Micro\HijackThis\hijackthis.exe
  
• After installing, you should get the user agreement, press accept and Hijack This will run.
  
• Select Do a system scan and save a log file. This will open a notepad file of everything Hijack This found, copy and paste it back here.
