SuperAntiSpyware

Free/Paid, California, USA
http://www.superantispyware.com/
SuperAntiSpyware is a program similar to MalwareBytes. Paid version has real-time protection. Recently, it doesn’t seem to detect as much malware (though it finds plenty of cookies, which are not harmful). This program also automatically loads with the system, and frequently prompts you for product updates. Not Recommended.

Not Recommended AntiVirus

Advanced SystemCare – Very poor software
Ahnlab – Company’s focus is developing software in a foreign language, most programs not available in English
CA Antivirus – Very resource intensive, poor performance
CYSEC – The individual file scanner uses a service like VirusTotal. The full scanner uses a Trend Micro program. No real time protection.
Immunet
PC Tools – Discontinued
PSafe – Not available in English
Qihoo – Discontinued English version
System Mechanic Pro – Junkware, in our opinion
System Shield – Also Junkware, in our opinion
