Here I think folk know my answer. The best antivirus is you. Why? Because even the best antivirus can't stop you from installing a trojan today.
Use Avast's uninstall tool then head to Ninite.com and check off Avast and get the protection you liked for free.
Right now, I am using the Avast antivirus in my PC, but its expired now. I want to know about latest & the best antivirus online.
Can someone suggest me?
