I'm looking to buy Emsisoft Anti Malware. I came across this site yesterday that is offering a 50% off coupon, see link below. http://www.curatedsoftwaredeals.com/coupons/emsisoft-internet-security-pack-discount/ When I clicked on instant button it take me to the Emsisoft site where the coupon is applied. How do I know for sure this is the real emsisoft site? Here's the Emsisost site it opens ups. https://shop.emsisoft.com/34/?affiliate=20056&scope=checkout&cart=40106&coupon=E20056 Do I need to do an IP look up? Thanks.
