Inactive Japanese Porn Malware

I was visiting some Japanese websites to view manga images. I notiiced later a file in my
download folder. Foolishly, I clicked on it, and watched in horror as it installed sometthing.

Now, every 5 minutes a window pops up with japanese porno on it.

I saved the original file, and have it zipped up. It seems to be a self-executing zip file in exe
format.

When I log on to the computer, I can see a windows command box (black box) open and doing something. There is a file listed in 'applications' with no name that I am unable to terminate.

I can see nothing unusual in hijack this logs or malwarebytes scans.

The file infected a non-privleged account, and the administrator account is not infected.

Attached are two screen shots, one of the pop-up window, and one of the task manager,

I was unable to upload the 7-zip file that includes the original executable that I ran to get infected, it was rejected, however I can email it.

Here is an update:

Apparently the extracted files create a registry entry that runs an HTML-application

The registry entry: HKU\S-1-5-21-6372259613-1446327078-3904827135-1003\Software\Microsoft\CurrentVersion\Run\webkirin

will execute C:\ProgramData\kirin\MPM4P73S.bat

which will start "MSHTA MP4P73S.d" which is a local web page with obfuscated javascript that lazy-loads content from Japan or China.

Deleting the registry entries and the folder (C:\ProgramData\kirin) should fix this.
