[11] Now you will learn how to scan your whole PC for viruses. It will take a long time. So do not do it during this workshop.
The way of scanning whole computer system is called "Full Scan". There is another called "Quick Scan". It scans limited parts of the computer system because they are likely to be attacked. Therefore, "Quick Scan" runs quickly.
In order to run a full scan, click "Scan options".

Save BitLocker access key, if it is enabled.
[13] Since Windows10, an encryption technology named "BitLocker" is introduced to prevent the access to your data in the case that your PC is stolen. Even if an user can access the PC or the internal stroage physically, the authentication is required to obtain the readable data from the storage. If "BitLocker" protection is disabled currently, future Windows Update may enable it without your agreement. Therefore, you should learn how to manage the "BitLocker" protection, and store its access key periodically.
[14] Some laptop PCs with preinstalled Windows OS might have already enabled the "BitLocker" protection. If you open the system drive on your PC: ① click the "folder" icon on the task bar to execute "Explorer" application, ② select "This PC" folder from the side panel, ③ check the system drive and whether its has a padlock icon. If a padlock icon is found, "BitLocker" protection is already enabled.
[15] If no padlock icon is found, it means "BitLocker" protection is not enabled. If requried, please check the appendix of the chapter how to enable it. If you are in hurry, you can proceed to the next chapter, but be careful that "BitLocker" protection can be enabled accidentally, and if you leave it without storing its access keys, you could be unable to access your data on your PC. You must learn how to check the BitLocker access keys.
[16] ① click "loupe" icon on the task bar to start search feature ② enter "BitLocker" ③ start "BitLocker Manager".
[17] Choose "Back up your recovery key"
[18]
There are several methods to store the recovery key (access key), the easiest is the "Print the recovery key"
[19] ① choose "Microsoft Print to PDF" ② click "Print"
[20] You would be asked to locate the destination of the printed PDF. ①Please choose the "Desktop" folder", and ②give the appropriate name of the output file, ③ click "Save".
[21] After you find the PDF file on the desktop, ① open it and display the identifier ② and the recovery key ③. Please take the identifier and recovery key with your mobile device, or you can save this PDF file to the external storage.
[22] After the storing the access keys, please proceed to the next chapter.
(Appendix) How to enable "BitLocker" encryption.
[23] If "BitLocker" is not enabled, there is only one meny in BitLocker Manager, "Turn on BitLocker".
[24] When you click "Turn on BitLocker", you would be asked how to store the recovery key. Please find the description in above.
[25] After the storing the access keys, you would be asked the data to be encrypted; "individual data" or "whole drive".
[26] You would be asked the algorithm of the encryption. If your PC was originally running an old version of Windows 10 (older than 2016), and there is a possibility that you may restore the original condition in future, "compatible" mode would be safer.
[27] "Run BitLocker system check" would be safer.
[28] You may be asked to reboot your computer.
