Seriously, should we believe in cloud antivirus as the only layer of protection? Most of these like Panda Cloud, Webroot Secure Anywhere, Kingsoft AV etc can work with other traditional antivirus. So, should we use them together? I think so or you may use AV that uses combined technologies. This conclusion is a result of my experiences with Webroot Secure Anywhere & Kingsoft AV (I use both together) when I had a internet connection outage in my place for a week. I almost got an infection which got blocked with Zemana. Later I found that none of these two detect any of the Virus samples I have with me. Today, after getting the connection back, I saw that both are detecting most of the samples. So I am going to uninstall both or any one of the two and use a traditional AV. What's your take?
