Hi all, as the title says I have a few questions about the anti-virus in 2013. I opened a new thread, since the nature of the topic changes very fast and I don't want old knowledge. First off, I installed Windows 8 Pro x64bit recently and it came with Microsoft Security Essentials- the "new" , not v2.1 that has been around for a while. It updates regularly and I have used MSE before. I am ok with the program, but is it reliable enough for an average user (e.g student)? It's good in removing malware, but not so much in stopping it on the first place. Second, this bug that my PC is not protected enough has caught me and I am asking myself: Is there a significant difference between paid and free anti-virus in 2013 packages? The first one that comes to my mind is AVG free 2013- which even has an Identity Protection. Free: no firewall (except Commodo), no parental controls, no support. I just saw in the Free-programs topic here: Roboscan - and it seems pretty solid, I might actually give it a try. What about PC Tools TreatFire? Ad-aware? Malwarebytes? - never used these.
