Having studied their Linux Antivirus (TrendMicro ServerProtect), it&#x27;s far from a clean, safe and well maintained piece of software:<p>* It comes with its own http server (apache, with a conf file mentioning NCSA (!))<p>* Their realtime kernel module barely compiles (on quite old kernel versions), has a disgusting code and Makefile and makes the computer slow or simply crashes when it kind of works.<p>* They ship their Antivirus with quite old libraries, some compiled more than 10 years ago, and some probably impacted by several CVEs (openssl &lt; 1.0.0, quite old libxml).<p>* Their init scripts are an ugly thing written in perl lauching several services in one script.<p>* Their rpm packages are just mindfucking. You have one rpm package to install the software, and other rpm packages to patch it... WTF.<p>From a piece of software, running as root (or even worst, in kernel space), written in C and analyzing untrusted inputs by definition, it&#x27;s a bit worrying to say the least.
