Thanks so much for Shadow Defender. The fact that a worst-case malware infection, or a glitchy Windows update can be completely reversed with just a single reboot is amazing. I, like so many people, have recently become increasingly aware of just how vulnerable our computer systems are to outside forces. So, I also recently purchased Rollback Rx, and now with the integration of Shadow Defender, I hope these two excellent pieces of software will provide a greater overall safety net for my Windows 7 system. Again, thank you very much for always providing excellent software.
