See virustotal results for PHP Desktop Chrome with PHP 5.5.8:

Scanning PHP Desktop Chrome with PHP 5.4.24 is OK, no trojan detected by 
Antiy-AVL:

The OpenSSL shared library libeay32.dll (version 1.0.1.5) that is shipped with 
PHP 5.5.8 is detected as trojan by Antiy-AVL:

Also when scanning files individually, Bkav antivirus is detecting 
VEX2819.Webshell false positive virus in "php.ini-development" and 
"php.ini-production" files:

We may try to use UPX compressor on the libeay32.dll to get rid of this false 
positive, a solution found here:

Or maybe upgrading to a newer version of PHP 5.5 will get rid of the problem.

We may also want to delete the php.ini-development and php.ini-production files 
to get rid of the Bkav false positive. It's probably a false positive because 
of the unusual extension.

In PHP 5.6.1 libeay32.dll is no more detected as Trojan. However 
php_opcache.dll extension is detected as AdWare.MSIL.DomaIQ by AegisLab - this 
extension will be removed from phpdesktop binary release.
