[QUOTE="rain2reign, post: 960471, member: 88069"] Regarding this point, it might be interesting to point out that It's a default behaviour for years, but it can be toggled off by enabling/ticking the setting “memory usage optimization” if you would like it to use less RAM. The definitions (by default setting) are loaded into the RAM itself and then used for scans and protection. Which makes scanning faster, than doing from a drive, like a SSD, which you can test the difference with Emsisoft Emergency Kit (EEK) or by simply turning on the memory optimization setting. Both have their pro's and cons. In general, you'd want it to use RAM, rather than pagefile and disk activity for better perfomance. I think Bitdefender and one or two others started using the same idea in their security solutions. If the RAM is around 300-400 MB, then it's operating within expected RAM usage.
