Now the virus is really very powerful, so that anti-virus software can not start the normal has been very flattering. Recently I ghost.pif is this kind of virus, it in the antivirus software installation directory to forge a malicious ws2_32.dll file, resulting in anti-virus software at startup can not load the correct ws2_32.dll file, the "0XC00000BA" error.
I created a new batch with file name A, which prevents virus from disabling antivirus software, as follows (in bold):
Turn off echo @echo off
cd\ Conversion to root directory
CD/D%systemdrive% conversion to System packing directory
CD program Files\ rising\ Rav into antivirus installation directory
Rd ws2_32.dll/s/q Delete ws2_32.dll files
Copy%windir%\system32\ws2_32.dll will system32 below Ws2_32.dll Copy to antivirus software installation directory
attrib +s +h +r ws2_32.dll set Ws2_32.dll to read-only files, system files, hidden file properties.
Put the batch on the desktop, if you encounter a fake Ws2_32.dll file to disable anti-virus software such viruses, double-click it can normally use antivirus software.
