special software for data recovery. There is a risk that people of bad faith might read and misuse the critical
data on hard disk drives for unexpected purposes.
To prevent leakage of data, it becomes very important that you take responsibility for deleting all the data
from the hard disk drive when you dispose of, sell, or hand over your computer. You can destroy the data
physically by smashing the hard disk drive with a hammer, or magnetically by means of strong magnetic
power, thus making the data unreadable. But we recommend that you make use of the software (payware) or
service (pay service) specifically developed for the purpose.
For disposing of data on the hard disk drive, Lenovo provides the Secure Data Disposal tool. To download
the program, go to:

unauthorized access, intrusions, and Internet attacks. It also protects your privacy.

Protecting data against viruses

Lenovo provides a full version of antivirus software on your computer with a free 30-day subscription. After
30 days, you must renew the license to continue receiving the antivirus software updates.
