IMO, An Anti-Malware really isn't necessary if you have an Antivirus Installed on your PC... In fact, the Anti-Malware is an complement for your antivirus, act as his, and will detect an large percentage of False-Positives... The Antivirus Companies, have large money to pay many workers 24h per day, it's because have an pay version, it's different of Anti-Malware Companies, pay version without an large money and workers...
An firewall is always an good choice, because some bigger percentage of free antivirus not contains an embedded firewall, we have some good options for free in the internet... I recommend the COMODO Firewall FREE, as your FREE Internet Security [Has embedded the firewall].
