I purchased this because of many computer reviews online and the deal was just too good to pass up. The digital download was easy and thankfully I'm not being bombarded with advertising for any add-on programs like some of the other digital systems out there. I haven't had any security issues. It seems to integrate with Windows Defender and monitors viruses, spyware and malware. This has kept my computer in top shape since I bought in and has lots features you can use to tweak your computer, I had a question and their support was right on it. I've used iolo products before and glad I was able to find an affordable way to get back with them. Highly recommended.
