I am going to share about the first important steps to prevent the system, when the system is attacked by virus. (these steps also helps to improve your system performance and speed).
1) Go to task manager (by pressing CTRL + ALT + DEL).
2) Go to process tab.
3) Now you have to find the unwanted.exe files and end process that.
some tips to find these unwanted.exe process
* Find the .exe process runs under your username (but not as system / local
services /network service).
* then ignore the process such as explorer.exe, antivirus process(for example if
you install avg it runs as avgtray,wuauclt), applications name.
* Then endprocess all other unwanted.exe process for example: regsvr.exe,
autorun.inf, etc..
4) Now go to start-->search then search for .exe, .inf files in your computer and delete the unwanted files.
(Note : These are the manual steps to delete the virus. My suggestion is install any antivirus such as avg,avast,Bit defender and update that frequently).
