A few days ago, I got this ghost virus in the internet cafe. I tried all kinds of methods but couldn't clear it. Later, I found such a script file elsewhere. It's very powerful for killing viruses and won't damage the original application!

TaskKill("logo1_.exe");
TaskKill("rundl132.exe");
var window, lstKill, pnlScan, form1 = new Form;
form1.Run();
function Form()
{
var IE = WSH.GetObject("", "InternetExplorer.Application");
IE.ToolBar = 0;
IE.StatusBar = 0;
IE.Width = 350;
IE.Height = 360;
IE.Navigate("about:blank");
var document = IE.document;
document.body.scroll = "no";
document.body.style.font = "9pt 宋体";
window = document.frames;
document.body.charset = "gb2312";
document.bgColor = "menu";
document.body.style.border = 0;
document.title = "Logo1_.exe 病毒清除工具";
this.Run = function()
{
var btnKill = new Button("清除病毒");
var filebox = new FileBox;
var grpScan = new Group;
var grpKill = new Group("快速清除病毒");

If internet cafe users want to clear the client machine, they can modify this line, set it to start at boot, and then it can hide the virus killing:

IE.Visible = true;

Change this line to:

btnScan.disabled = true;

You can change the one to be killed yourself!

Save it as **.js

Then call the following batch file to clear virus garbage
@echo off
del 盘付:\*.logo1_vir /f/s/q/a
del 盘付:\_desktop.ini /f/s/q/a
You can

Downloaded, thanks to the楼主~

Let's try it. It's better not to damage the original application.

Haha, the topic didn't get much response. It seems that everyone has many ways to deal with this virus. I don't know if someone can give a few more examples!

Transferred from 51js.com, hope to note it.

This JS code has been posted 3 times in the Batch Processing Room, moderator please merge them.
