Special characters in filename leads to starting virus executable

[depler]

I've just downloaded torrent with one file in it - the formal name of file should be "123.avi.exe" (which is typical for viruses and trojans). Now, interesting thing is that name is encoded in UTF16-LE as following bytes:

FFFE3100320033002E002D202E202D202E206900760061002E00650078006500

which gives us strange, partially reversed over ".exe" text (try to move cursor left-to-right and you will be surprised):

123.‭‮‭‮iva.exe

But the bad part of all - is that utorrent showing non-suspicious ".avi" extension while when you double click it in GUI - it goes as as ".exe" and program runs.

You can test it yourself by creating dummy file with the name I wrote above. Screenshots attached.

Please fix this by preventing to run executables if it's name contains special characters (like Total Commander does).

I will get it looked into.
