Avast vs Windows Defender
« on: September 29, 2018, 06:50:15 PM »
1- Did you wonder if Avast has the largest database of Windows Defender than Microsoft?
2- Since Microsoft is installed around the world, I understand that the largest database is hers, because of collecting threats with great volume.
3- Microsoft it uses several servers to do analysis, according to the link that I will put below.

4 - The work this man who is speaking in the video and great, he has Microsoft's MVP, with what he says has a lot of basis in what it says about security.
5. Did Windows Defender become the safest for reasons he explained?

Hi Pol, personally IDC about such videos (esp. outdated ones from 2016 ;)).

Size is an imponderable and not something that you can use as a definitive answer to who has the most or best database.

Avast is constantly optimising its database, tweaking signatures to detect more than a single virus signature. 

If there was a single detection signature for every piece of malware, the database file size would be massive.  This would make it pretty unwieldy and slow.

I would also add, that regardless of size of data base for known virus' (whoever has the larger) malware detection is very much now more about Heuristics, AI and Behavior analysis/detection components.

Probably you are talking about 'database of virus definitions or signatures'. Since Avast is a dedicated Security Suit, I think Avast has more virus signatures than Windows Defender.

Avast is at least 1000 times better than vs Windows Defender, enough to say.

One should also take in consideration PUP detection and blocking suspicious destinations like PHISHING sites,
just there where cybercriminal activities lure.

Windows Defender does not equal normal AV in these respects nor even has Google Safebrowsing grade protection.
See Pondus's response on this matter. So Windows Defender is even catching up here. ;)

Of course one adds a good ad- and script blocker to the browser like uBlock Origin and uMatrix,
or MBAM alerts for certain content alerts.

Moreover I write this post inside the Avast Secure Browser and there is a reason for that too.

Windows Defender is not bad for the moments that your AV for one reason or another does not work,
for instance because of critical Window file's FPs, but not under normal conditions.

Hi Pondus,

Thanks for given the latest information on this. Apart from this, what is the actual difference between Windows Defender and free AV?
Is it heuristics or can they be compared on an equal basis?

If you check AV compare they are doing very good
