Is Avast Free Really protect!

hey, I just want to assure that " Is Avast Antivirus free edition really protect my PC from virus and remove them or I have to upgrade to paid version?". I heard some people are saying the free edition just show the virus but don’t really delete it so it won’t protect your PC, so is this true or not.
on another hand I have about 2 or 3 years using Avast free version on my PC and smartphone and didn’t get any problem caused of a virus.
really I am confused about what to believe!

Is Avast Antivirus free edition really protect my PC from virus and remove them
Yes it realy does ;)

Can you Trust Free Anti-Virus? https://blog.avast.com/2009/08/04/can-you-trust-free-anti-virus/

avast! Free Antivirus for Mac gets first place for malware detection https://blog.avast.com/2013/10/08/avast-free-antivirus-for-mac-gets-first-place-for-malware-detection/

So why I need to pay for other editions if the free one will protect me and delete virus from my PC 8) :o

the payed have extra features, firewall, spam filter… https://www.avast.com/en-eu/index

The other versions have other elements not in the free version, firewall, safezone (virtualising), etc.

I have been using the avast free version for over eleven years and no infections.

Greats
I love it so much not only cuz it is protecting me, but also cuz it doesn’t slow down my computer, like some other anti viruses does.
this is why I am keeping use it and i will not try another, this is comforting me.
but i wanted to make sure that people is wrong to say it doesn’t protect. 8)

You can test functions with EICAR test file www.eicar.org/85-0-Download.html

can you explain what is this and how can use, please?

It is explained on the website www.eicar.org/86-0-Intended-use.html

i think that avast free antivirus is very effective more than other software. i say that after using a lot of software to protect me from viruses, and i found that avast free version has a high protection system than other paid software

I wouldn’t rely on the ability of any AV-software to delete all malware parts on my computer.
If something is wrong (installation failures, malware …) I go back to a clean windows version that I store regulary with an image programm.
