The mouse is sometimes tampering, don’t listen to the command, don’t panic, teach you to solve it

Phenomenon: The mouse is sometimes tampering and does not listen to the command. I suspect that there is a virus or a Trojan, so I have not found any problems with Kingsoft Internet Security, iparmor 5.33, and the cleaner. But I found several tasks without paths, versions, and any information under "System Information & Rarr; Running Tasks". I don't know if there is any relationship with this. What are these three tasks, can I delete them, and how can I delete them? This is a NIMDA virus. The solution is as follows: (1) Check the temporary folder for the presence of MEPXXXX.tmp and MEPXXXX.tmp.exe files. XXXX is a string consisting of random subtitles and numbers. (2) Check if C:\\, D:\\, E:\\ has the httpodbc.dll file. (3) Whether the bandwidth is seriously occupied. (4) In the Windows 9x/ME system, whether the LOAD.exe file exists in the \\Windows\\ system directory. (5) In the Windows NT/2K system, there is a CSRSS.exe hidden file in the \\Windows\\System directory. It is recommended that you download the Symantec and Trendmicro killing Nimda_E virus tools for detection and removal. Killing steps: (1) Download FxNimdaE.com and store it in the system. (2) Stop all running programs of the system. If your system is Windows Me, you must stop the system recovery feature of Windows Me, because the virus may be automatically saved in the backup directory. Double-click to run FxNimdaE.com. To run this program, you need to log in as the system administrator account, stop the IIS service before the operation or unplug the network cable to avoid re-infection during the cleaning process. Then click the Start button to run the program until the report says the system has cleared the virus.
