Thank you for your words 
The usual way I notice these things is by checking out some of stuff I post here is checking websites I visit in online scanners out of curiosity/doubt, or when I notice something weird when visiting sites. Part of this could be my general anxiety/slight possible cyberphobia. But nothingless I as much as anyone I like being more secure on the web, though it migh make me paranoid in eyes of some people, since I usually worry about security of my PC even with all antivirus/malware & browser security tools I use. :-[ Byt notheless I most of all try to do my part keeping web browsing safe for everyone else and myself.
