I recently started getting popups about allowing Dashlane to make changes. I never knowingly installed Dashlane and don't know where it came from. I did some looking on line and it appears that the program can be helpful. Should I leave it or remove it?
you didn't install it and don't know where it came from it may not be genuine. If you think the program would be useful, I'd erase/delete what you have and then download a fresh copy from their verified website.
If you did not explicitly install Dashlane then my take is that you should do everything in your power to purge every trace of it from your system. Consider that the program/add-on/plug-in is there to collect passwords and login information and store them somewhere (where?). Can you see any downside to giving something you don't know anything about this information? Like f'rinstance if it collected your banking and credit card information for later use?
I did a bit of searching for information about this program. This bit might be of interest:
"Should I remove dashlane?
The internet security community strongly recommends that you remove Dashlane if you find it installed on your machine or attached to your internet browser as a browser add-on or extension and use reputable Antivirus or Anti-Malware software to eradicate any existing malicious files.Aug 22, 2015"
The net effect will be you won't get to see content on some websites because they will ask you to disable it in order to enter their site. Ads, after all, are what pay for the website's expenses.
I use an ad blocker and it does subvert the advertising here on WoodCentral and elsewhere. Because of that, I feel it's only right to contribute $$ to this and other forums that are valuable to me. (Just like public radio but without the fundraiser drives!)
Even a little bit every month probably helps keep the websites up and running. Paypal makes it painless.
You can usually "unblock" specific sites to 1)allow the ads and 2) see the content
I'm aware of that. However both static and popups ads annoy me. And I think they are wasted on me - as far as I can remember I've never once bought something I've seen in an ad on a web site or even purposefully clicked on an ad out of curiosity.
Ad blockers stop you from having to watch absurd long ads in videos, etc, and they cut down the clutter on your screen on many websites where the content is a small spot in the middle and ads clutter everywhere and flash all over the place.
