I have downloaded the latest version, and every time I attempt to install it, I get to the first screen that prompts me to click "Next", and then the installation dialog disappears. It seems like something is intentionally shutting down the installation. I have Symantec Antivirus installed and it appears to be working properly. I have Windows Defender installed, and it also appears to be working properly. In fact, I did a Full Scan, and Defender found two nasties and it also found the remanants of a keylogger that I was testing several months ago buried in a System Restore volume. But even after removing the two spywares that Defender found (Win Zapper and Dead Pool), I still cannot install ewido. I also tried downloading and installing Spybot Search & Destroy, and it does the same thing as the Ewido install. I get to the screen where I agree to the terms and conditions, and wham! the install closes.
