There are lots of Antivirus software are available in market, you can get it by purchased or free trials from internet. I am using Ashampoo Antivirus software for protecting my laptop from viruses, malwarms, and threats.
The disadvantage of this software is it requres update daily, and the update is not few files, it will downloads more than 500 files daily and after that it will restarts its engine but it cant, and the process hangs, so you have to force close it via task manager. bad experience.
