False positive Win.Trojan.Bamital-1158 for explorer.exe ?

From time to time I am checking my Windows partitions when using Linux on the same machine.
Yesterday I got:
/windows/C/Windows/SysWOW64/explorer.exe: Win.Trojan.Bamital-1158 FOUND
/windows/C/Windows/winsxs/wow64_microsoft-windows-explorer_[...]_6.1.7601.17567_none_[...]/explorer.exe: Win.Trojan.Bamital-1158 FOUND


The clamscan call:
clamscan --max-recursion=300 --max-dir-recursion=300 --max-files=1000000 --max-filesize=4095M --max-scansize=4095M -r  --detect-pua=yes --log=reportclam


Both files are the same according to Linux diff.
clamscan is the only AV that finds these Trojans, I also tried VirusTotal and Metascan on the Web.
The other AVs that I use for Linux also do not find these 2.


This explorer.exe has a MD5:
md5sum explorer.exe
8b88ebbb05a0e56b7dcc708498c02b3e  explorer.exe


Is this a known false positive for clamscan?

Best regards
Pete
