I don’t actually have this virus myself, but a friend of mine does and I promised to help him. I’m not a computer expert by any means, but I’ve been able to help him with different pc-related problems in the past. This is beyond me, though, so I hope someone here can help.
He’s running avast 4.8 home edition, and from what he’s told me, it keeps finding this virus, but whether he deletes it or moves it to the vault, it keeps coming back. We tried some online scanners, but they didn’t help at all. From what research I’ve done on these forums and others, it seems like this virus is very difficult to get rid of, but hopefully someone here will be able to help.
[]Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
[]Under the Custom Scan box paste this in
Alright, thanks to you both. I don’t have access to the pc right now, but I’ll post the info as soon as possible. I really appreciate that you’re taking your time to help.
I hope this is correct. One thing I noticed during the scan, though, is that at some point it looked for newly created files. My friend tells me that his problem started a couple of weeks ago, so the infected files may not be brand new. I don’t know if this is important, but there it is.
Anyway, I’ve managed to appropriate my friends pc, so I should be able to respond faster from now on.
OK here we go this will be a fairly long fix so take note of the steps as they must be done in order

I tried running combofix, but it tells me that I should shut down avast before continuing. I tried disabling the on-access protection, but combofix still complained that avast was running. Should I just ignore this, or is there some way to completely shut down avast?
I also have tdlcmd.dll and cannot get rid of it. My avast lets me delete it, but it keeps coming back. I have also tried PrevX, malwarebytes, spybot search and destroy. My computer seems to work ok, but I can no longer even go into safe mode.
I saw you post to a guy with a similar problem, but you said your solution was specific to him. Is there anyway I can get your help?
