mostly i dont use them , but if needed i choose avira for home users , kaspersky for people use to spend on internet & portable devices ( especially friends or other unknown peoples for copying movies etc...)
for pros and cony just Google it .. its better to get more ideas on your own instead of depending on others for all details..
The best antivirus is your brain. Second best is the removal of your mouse and keyboard.
Lots of options, google should reveal them to you.
