Prompt ntsystm.exe error when booting

Q: The ntsystm.exe error message appears when my computer boots into the Windows XP boot screen: "ntsystm.exe - Corrupted image: C:\\Docume1\\STEPHE1.STE\\LOCALS1\\Temp\\ula2.tmp For invalid images, please check your installation disk again." And each time the TMP file name is different, I can't find any files in this folder, and the ntsystm.exe file can't be deleted. How can I solve this problem?
A: This is the performance of the "high wave" virus in the computer. The cleaning method is as follows: first disconnect the network, press the "Ctrl+Alt+Delete" key combination, click the "Process" option in the task manager, find the process named "ntsystm.exe" and click "End Process"; Then find the "ntsystm.exe" file on the hard disk, delete all the found files; open the registry, search for the key value of "ntsystm.exe", all deleted, restart. To prevent re-poisoning, install critical security patches as soon as possible, and install a virus firewall, and pay attention to timely update the virus database.
