Avast vs Windows Defender
DavidR:
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.
schmidthouse:
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.
New_Style_xd:
Thanks for the clarification on the subject of the virus database.
DavidR:
You're welcome.
polonus:
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.
