I've never seen the issue you've noted. However I did beef up my browser security with Web Of Trust, Ublock Origin and Privacy Badger.
What are you doing to be safe on the internet?
I have read that Adobe Flash Player has many security problems and that it should be avoided. Every day many websites that I go to used Flash Player including my bank and my mutual fund. I have been doing without it on this computer but I do have it on another computer which is old and slow and is down in the basement, thus requiring that I go down to the basement whenever I must use Adobe Flash for a certain type of banking operation that I don't use more than a couple of times a month. My laptop which is what I use daily does not have it installed and since it runs very well, I would hate to have it get corrupted What are your thoughts on this?
