Hello all,

First let me say that I have used ComboFix successfully many times, and it is a great tool.

Yesterday, I encountered an issue. I ran the utility, and received a popup saying that mscytijvv.dll was attempting to connect to combofix, and it would be disabled. Combofix renamed the file to mscytijvv.dll.vir, and attempted to continue. Then a barrage of popups began to appear, telling me that for each utility combofix tried to run, it could not find mscytijvv.dll! I promptly stopped combofix from running.

I encountered the same issue on a second, different PC today.

Is this a new nasty that is out there?

Any help would be appreciated. Thank you.

Unfortunately the author of the tool does not want information on how Combofix works on public forums.
Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

The only public information that is available can be found at this guide:

In addition, ComboFix is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert." It is NOT for private use. Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

Running ComboFix by yourself is like performing open heart surgery on yourself--the scalpel and other surgical tools that is ComboFix is meant to be wielded by a highly trained surgeon only in emergencies or dire circumstances. When the surgeon is thru s/he leaves the room. So combofix should be removed from a system once it has accomplished its job, unlike an AV that is there to protect you from future infections.

. . . CF does make some alterations to your system if you run it. Even if you had no malware removed and run the uninstall command, some things may be different now on your system. I can tell you that one thing is that all your restore points will be flushed out and a new one created. There is a good reason to do that when you have a severe infection--but if you aren't infected you might need those restore points.

Read and abide by the disclaimer people. It's there for a reason. Stick to running and protecting yourself with a good AV and firewall and an anti-malware scanner or two. If you feel you need a second opinion, try running online scans. If you feel you might need surgery, come here to BC and ask for help--that is what we're here for.
