Do you use Windows? And do you have an antivirus program installed? Is it AVG? Then go ahead and uninstall it.
Generally speaking I am not a fan of those programs. People with way more knowledge than me refer to those programs as snake oil.
Yet, I have used Avira, along with CCleaner and Spybot Search & Destroy, to clean up computers. All those are free programs, but not free and open source. They can help cleaning up. But they do not really prevent the mindlessly browsing internet user from catching malicious software. Point in case, recently I had to clean up a computer, and although AVG was installed and running, I found 66 problems, including at least five malicious programs. One of which was a trojan. So, AVG wasn’t really helpful there.
And now AVG is turning against its users. As someone on Slashdot publishes here (quote, emphasize mine):
We collect non-personal data to make money from our free offerings so we can keep them free, including: Advertising ID associated with your device; Browsing and search history, including meta data; Internet service provider or mobile network you use to connect to our products, and Information regarding other applications you may have on your device and how they are used.
So, AVG turns its protective program into spyware and adware. Advertising IDs, browsing history, metadata, you can be identified by that pretty accurately. All the stuff they collect together makes your data unique. This is personal data, no matter how AVG calls it. And of course, AVG has no way to check, what the buyers of your data do with it.
Unless you are like sheep, walking to the slaughter house voluntarily, uninstall the crap.
