I've bought McAfee VirusScan in July 2017 with one year subscription. McAfee VirusScan comes with a real-time scanning, schedule scan, vulnerability scanned, shredder, Defragmenter, etc.
Firstly, I've been using it Windows 10 and I found so many problems like deleting some some .exe files which are much necessary, Steam files and some DirectX files.
Secondly, when I installed Windows 7 Ultimate and gone for McAfee VirusScan, I found that it's not installed correctly leading to termination when double-clicked to open it. And due to it, my pc gets slow.
I'm still having subscription but I'll not use it because it's a malware for my pc. I'll not recommended that. Thank you.
