Hard drive too full to download anti virus clean up

You may download and try the CCleaner with default values, which will delete the unnecessary temporary files, downloaded programs and other junk like report files, log files etc.

You may also use the Disk cleanup feature in all the drive's properties (right click and select properties - General tab and select Disk cleanup button). This will additionally clean the system of unnecessary files.

In the same General tab you can keep a check mark on "Compress this disk to save space". This will additionally give you some more space (but at the cost of some performance loss).

You can also delete the old restore points on the drive. If you are not using the Hiberbate feature, you can delete the hiberfil.sys file for further space savings.

Overall all these changes should be able to give you a breathing space. Then install a good Anti-Virus program (like the free Microsoft Security Essentials), update to latest updates and clean the system.

Here is the solution. Of course, you will need to prepare the usb stick on another computer.

PERFORM AN OFFLINE SCAN
Bootup your computer from the USB stick
Windows Defender Offline will automatically perform a quick scan.
After the quick scan finishes, Choose Full Scan
Select all of your drives

The initial, full scan can easily take several hours, but
Remember, your computer is being very thoroughly checked for all types of malware.

See you back after several hours (I said the check is thorough.)
