When I first tried it, it looked great and then I started havig problems. I had checked the initial ZIP file and it showed clean, likewise with the extracted .exe file. However, after running into some weird problems after using it, I check the "installed" .exe file and it showed "Spyware.password.xGen".
Looks like it might have a password sniffer or xGen virus. Initial virus, malware and spyware checks show it clean. But once installed a scan indicates it has spyware/virus (xGen) and an initial invocation, it goes to the internet to download a "hidden program". Malbytes and Avast detected the xGen code and Zone Alarm caught the "hidden module" download. It issued a message stating "Hidden start (32-bit) is trying to launch 'C\WIndows\SysWOW64\cmd.exe' or use another program to gain access to privileged resources". It also replaces Adobe Reader amd makes itself the default without asking. I used "Advanced Uninstaller (or Revo Uninstaller) to get rid of it and also the registry entries it made. Use at your own risk. Too bad, because it did a nice job of flipping pages of a PDF.
