Sophos Antivirus for linux not disinfect the file

Dear Sirs,
I have installed on my home computer under Linux Mint 18.3 64bit Sophos antivirus for linux. I check it is work fine with www.eicar.org. Every time after starting pc I do the check:
sudo su
/opt/sophos-av/bin/savdstatus             
/opt/sophos-av/bin/savconfig query LiveProtection
cd /opt/sophos-av/bin/
./savupdate

A few days ago in my web e-mail I received "Test.rar". It was a virus file. First I unrar it, then check with terminal for virus:
./savscan -all -f -dn -b -archive /home/svetliof/Internet/ and I get:

Full Scanning

>>> Virus 'Troj/DocDl-DVM' found in file /home/svetliof/Internet/Test/ККК.doc
                
2 files scanned in 6 seconds.
1 virus was discovered.
1 file out of 2 was infected.

End of Scan.

Ok, it is a virus. I try to disinfect the file: ./savscan -di /home/svetliof/Internet/Test/ККК.doc , but nothing happened:

Quick Scanning

>>> Virus 'Troj/DocDl-DVM' found in file /home/svetliof/Internet/Test/ККК.doc

1 file scanned in 6 seconds.
1 virus was discovered.
1 file out of 1 was infected.

End of Scan.

Am I using the command -di in correct way? Or Sophos antivirus for linux can only detect, but not disinfect the file? This file in not important for me to be a disinfect, but to practice how to deal with some mine if is infected. 
Thank you very much,
