Hey guys, I've used Microsoft security essentials for years, but after I came across an article on PcMag about how obsolete MSE has become, I decided to install a "real" AV on my machine. My laptop runs Windows 7 on a second-generation core i3 and RAM 4 GB. I've read many reviews on acclaimed websites, and I narrowed my search to Bitdefender and Avast w/out an antimalware and a firewall. I found a poll on this forum about the best security suite and I'm quite surprised by the votes! Most reviews I went through put Bitdefender IS at the top of IS suites, and Avast free antivirus at the top of free (and lightest) AV.
