1, this is not necessarily true, the school computer does not necessarily have a virus, nor can it be said that 100% is non-toxic.

2. I suggest that you can download a computer housekeeper from official website, Tencent's computer housekeeper, before boarding the computer.

3, use computer housekeeper-antivirus-lightning killing, scan it first, 1 minute can be done.

4. If the scanning result is safe, it means that the computer is non-toxic and you can upload or copy files with a USB flash drive.

If you have any other questions, please come to the computer housekeeper enterprise platform again and we will try our best to answer them for you.
