Hey there, just new to the forum, however would like to say that i have CM launcher pro on my phone and have found it to be the best around for my needs and ability to customise etc., also have tried them all Nova, Arrow, Action... all are very good,however i still come back to CM., never any virus problem. as a previous comment the security through play store etc takes care of that so i would imagine it wouldnt be available otherwise, and i would also add my phone battery seems to appreciate CM and performs far better than the others,so in summing up yes im a compulsive app searcher and phone fiddler and love to explore whats available and CM does have a lot of companion Battery and Security apps etc, the safe lock screen is a good piece of development as well. so i do recommend to try , but take the time to arrange how you want things to look etc..
