Hello! Friends
I encounter this problem today. When I boot my PC, I keep on receiving this
security warning from my anti-virus software: Malware Win32 Trojan_gen
exists in the following path:
C:\WINDOWS\system32\Drivers\mchInjDrv.sys
I tried to delete or "move to chest" (as recommended) it. But it keeps
coming back when I reboot the PC. It is very irritating. How can I
permanently remove it? Is it harmful?
A quick Google for "mchinjdrv.sys" tells me that:
"MchInjDrv.sys is a driver for injecting code to other processes.
Publisher is legitimate:

But it is often used by malicious software. Kill the file mchInjDrv.sys
and remove mchInjDrv.sys from Windows startup."
In addition to the doing the above, I suggest that you do:
Go through these general malware removal steps systematically -

Include scanning with David Lipman's Multi_AV and follow instructions to
do all scans in Safe Mode.

When all else fails, run HijackThis and post your log in one of the
specialty forums listed at the first link above (not here, please).
Standard caveat: If the procedures look too complex - and there is no
shame in admitting this isn't your cup of tea - take the machine to a
professional computer repair shop (not your local version of
BigComputerStore/GeekSquad). Please be aware that not all local shops
are skilled at removing malware and even if they are, your computer may
be so infested that Windows will need to be clean-installed. Have all
your data backed up before you take the machine into a shop.
