There are many Firewall software and anti-virus that you can choose from. But I can suggest Panda or AVG. You can search other types in the internet for the free trial version. Just sure that you follow the process of installing of those software. Happy mylotting....

The best firewall base on my experience is ZoneAlarm, zonealarm can protect your PC from hackers. Good thing about this firewall is that ZoneAlarm is free for individual use. It's an easy to use firewall protection program that blocks hackers and other unknown threats. Also, it makes your system completely invisible to anyone on the Internet. I have personally used ZoneAlarm for years with no issues. It gives you the chance to accept inbound communications or turn them away and you can setup a list of programs that need to access the Internet that are listed as "ok". Zonealarm is very to use. It's not complicated to run, but still keeps out dangerous threats.
