I downloaded Ewido the other day and installed it. It really bogged down my system. It ran noticebly slower. Has anyone else had this problem? Is there something I can do so that it won't do this. I really like Grisoft's products. I have been using AVG for several years. I wanted to try Ewido. I use Spywareblaster, Spybot S&D and Windows Defender. I thought I could get rid of some of these if I used Ewido. Could running all four of these at one time have been the problem?
