I forgot to add ( in my presentation)
K9 Web Protection Free.
K9 Web Protection It looks like bogus app, but it isn't. It belongs to the
old, good Symantec. Light on system, it doesn't change home page neither search engine. It has a lot of options. I opted for protection against malware/suspicious/ spyware/ websites.
Definitely - I recommend it to all. A user has to register with an email. A user get an install file. No adds, no slowdowns, no spam in email by that corporation. I strongly recommend to try or even to test it. I did some tests. Super duper protection. K9 takes 3,5 MB of RAM
