Avoid this company, they are selling your browsing data to third parties. https://www.vice.com/en_us/article/qjdkq7/avast-antivirus-sells-user-browsing-data-investigation They claim they are now winding down that business, however, they do it only because of the pressure after being caught, I cannot trust them anymore. Not recommended, trust is hard to earn, but easy to lose, they do not appreciate it enough.

Another negative experience, it keeps installing without permission. Avast seems to be very eager to get their hands on your browsing data.

N.c.

Recent reports of Avast selling user data.

I thought this was a great extension, until it was revealed that Avast is selling sensitive information about your browsing habits!! I have disabled it until Avast comes clean. It's completely disappointing that a company that is supposed to protect you is actually ACTING LIKE MALWARE!!!

Recent reports of Avast (through subsidiary) selling user data.

Avast was recently exposed in a Vice/PCMag report which revealed that it sold web browsing data, including the sites you visit and the links you click, to third parties.

AVAST programs have been charged for data theft and unlawfully collecting and selling that data to third parties. Get rid of it!

BAD

Дважды на одни грабли? Нет, спасибо.

Avast is using this extension and their products to spy on you, and then sell your browsing information to data brokers around the world.

Blockiert sinnlos Webseiten als angebliche Phishing-Seite obwohl die Identität des Betreibers zweifelsfrei erkennbar ist und nichts auf Phishing oder andere malware hindeutet. Es gibt auch keine Möglichkeit die Blockierung zu umgehen außer das Add-On wieder zu deinstallieren. Was ich auch sofort machen werde.

Causes flashes of unstyled content in loads and loads and loads of sites (and has done for ages), to the point that it is hard to fathom how this passed QA and how the bug hasn't been fixed yet.

Installed without my consent after using Avast Software Updater to update my Firefox (along with 1 additional extension).

Didn't even know this was running on my FF, and it comes with the "Data sharing" checkbox checked by default! Awesome! Thanks for tracking me...
