Actually Jorge this was patched the day before you posted this.
By no means am I saying what MS did is correct it still was found quickly and fixed. Really as far as updates no different then any other anti-virus program.
These post have popped up for years. At least for the 11 years I have been here. It is really nothing more then a person opinion and what works for them. By the time these threads have been active for a period of time they don't really help anyone as so many programs are listed and many with good things said from the person the uses it.
True, just pointing out that Microsoft, just because it is Microsoft, doesn't do it better than other AV vendors. In fact, sometimes the opposite is true.
And you're also right about your conclusion: people generally tend to think whatever they are running is the best.
What I do cross off my list, however, are those AV vendors who have resorted to useless and counter-productive 'gimmicks' to make their products stand out from the competition: Symantec's WS.Reputation.1 being an example - someone should have sued them - as is other AV software (BitDefender, for example) that treats *any* application writing to, say, Public Documents (a perfectly legit folder to write to for several reasons), as evil ransomware and *silently* (this is the part that gets me the most!) blocking those writes making it look like the application is to blame, and this despite the application itself not being flagged as malware of any kind.
That is just laziness on their part, if not downright deception, and ends up doing more harm than good by hurting users and developers alike.
This is something I personally have never seen ESET doing.
