其它操作系统综合讨论区 » Why can a file that has been changed to system attributes using attrib still be deleted?

attrib "C:\Program Files\QQ2007\npkcrypt.sys" +s +r +h Hehe, this is mainly because there are too many recent QQ trojans. The main thing is to delete the following files in the QQ directory: pkcrypt.sys npkcusb.sys npkcrypt.vxd These few files lead to failure in confidentiality encryption! Why did I change it to read-only, hidden, and system attributes, but it is still deleted? How can I change it to ensure that it can only be read but not deleted? Please give your advice, thank you!

If a file is in use, it cannot be deleted.

By hand, you can set it to refuse deletion, but why can't it be done with batch processing!

Permission issues may also prevent file deletion.

The files of the system properties can also be deleted.
