Ahhhh 'puters and the internet. Ya gotta love 'em to hate 'em.
Tracking - no matter what you do, your computer and whatever search engine is tracking you, be it via search history (Google, Bing, etc), cache and cookies - and on your computer - you should delete at a minimum, every few days. I do mine at least once a day, more often if I'm on a lot. Firefox has a History drop down that you can empty plus a Tools drop down that will clear you cookies and cache. Next - Trojan Horses - here's a good (bad??) explanation : Trojan horse (computing) - Wikipedia, the free encyclopedia
Then you need a viruscide that you can use to do additional cleaning. I've been using AVAST, the free version, but also used their very inexpensive Pro version - and it works much better for an individual then Norton, McAfee or Kaspersky which are way too intrusive and really slow things down. Then there are applications that start when you push the 'ON' button, many of which aren't needed for start up and not only slow the start, but also keep grabbing some of the RAM (memory). Then your hard drive. Even if you delete something, there are traces left until such time as it get written over - or maybe not. This is how law enforcement nails undesirables. I have a terabyte of hard drives - chance of over write happening soon, slim to zip
Am I a 'puter expert - absolutely not. But have built several, gotten them to work well, but have not a clue as to what goes on with the innards. Heck, on the home built desk top, I'm still using XP, but only for another 9-10 months.
La. collecting sales tax - in New York, if the company has a presence, sales tax gets charged - AMAZON being one - if not a NY company, you are supposed to 'fess up and pay. Uh huh! Sure we will
Google - I will NOT use Chrome. Google already knows too much about me and shares with the gov't.
Posting comments on or about political sites - not any more. Call me paranoid, but my politics and the current administration aren't the same, therefore I try to keep a reasonably low profile. There are other reasons, but not for discussion here. I also try not to go to sites that have specific aggressive words or are probably being watched for big brother to get alarmed over.
Nolan - it is what it is. Tracking will tell a web browser company who and what to charge based on hits. They just carry it beyond reason so target you for 'crap'. With Firefox, you can download the ADBLOCK add on which will defeat 99% of the targeted garbage as the ads don't make it to your computer.
'Nuff said, lunch time
