Which Litecoin mining software is best?

Hello,

I'm a bit new to Litecoin mining but I'd like to begin. My GPU is a Radeon R9 290 which I'm sure is good enough to mine but I would like to know what type of software I should be using. My primary concern is trojans or viruses that are possibly hidden in mining software such as CG Miner or Reaper, which I have checked. My question is what software to use, and whether it will be safe to use. Keep in mind, I am using anti-virus software and most miners include some sort of hidden virus/danger.
Please assist me for best answer. Thanks in advance.
