[nabs-l] Accessible Antivirus programs

[Miso Kwak]

Hi,
I recently had to do a factory reset on my laptop. I used to use 
Microsoft Security Essentials but lost the program and not sure how I 
can obtain it. Also, I am trying to explore some other options.
The person who did the factory reset and backed up my data recommended 
AVG 2015 but I do not like this as it does not seem to be quite 
accessible.
Any suggestions for an antivirus program that is competible with 
Windows7 and accessible?
Thank you in advance.
