About Broad Notion

Broad Notion is a help resource about antivirus software and everyday computer security, written for readers in Australia and published by GRESKO s.r.o.

What this site is

This site answers practical questions about antivirus software and the problems that bring people to search for it: a computer that has slowed down, a link that was clicked and regretted, a text message about a parcel that was never ordered, a subscription that renewed at an unexpected price. Each answer is written to be useful without seeing your device, which is why none of them diagnoses anything.

It is not a news site, a personal blog or a review publication. There are no bylines, because the answers are written and reviewed by the GRESKO s.r.o. editorial team rather than attributed to an individual. There is nothing to download here, and no scan runs on this page. Where a paid product is relevant to a question, it is described as one option among several, and the links to it are paid affiliate links, which are disclosed on every page that carries one.

How questions are chosen

Questions come from the language people actually use when something has gone wrong: the phrases typed into a search box, the way a problem is described to a help desk, the way one person in a household explains it to another. A question earns a place on the site when three things are true of it. It is asked often enough to be worth answering carefully. There is something useful to say about it that does not depend on inspecting the reader's device. And the answer can be given without frightening anyone into a purchase.

Questions are left out when the honest answer would be "take it to a repairer", when answering would require guessing at the state of a particular machine, or when the only available answer is to buy something. A question is not added because a product happens to address it.

How answers are written and checked

Each answer follows the same shape, deliberately: the short answer first, then the causes that are most likely, then what to try that costs nothing, then when to go to an official source, and only then where a paid product may or may not make a difference. That order exists so that the free step always comes before the paid one, and so that a reader who stops reading after two paragraphs has still got the useful part.

Answers are checked against the published guidance of the Australian bodies whose responsibility the subject is — the Australian Cyber Security Centre, Scamwatch and the National Anti-Scam Centre, the eSafety Commissioner, the OAIC, the ACCC and the Australian Classification Board — and against vendor documentation for anything specific to a product or operating system. Where a claim depends on a particular version of Windows, macOS, iOS or Android, the answer points to the vendor's documentation rather than restating a detail that will change.

Pages are reviewed on a rolling basis and in full at least twice a year, and whenever a reader tells us something has changed or is wrong. The date of the most recent review appears in the footer of every page. Corrections are made directly on the page rather than appended as a note, because a reader looking for an answer needs the current one.

We avoid stating figures we cannot source. You will not find test results, scores, percentages of users affected, or claims about how many threats exist, because those numbers are either someone else's to publish or invented. Where a general claim is made, it is either linked to its source or written as general guidance.

The commercial relationship, stated plainly

This site earns money. Some links to Norton AntiVirus Plus are paid affiliate links: if you sign up after following one, GRESKO s.r.o. receives a commission from the affiliate network that operates the link. You pay no more than you would by going to the vendor directly.

So yes — the product mentioned on this site is one the publisher has a commercial relationship with. That is worth knowing when you read what is said about it, and it is why the answers on this site are written to send you to free options first and to the vendor's own site for product details. What the commission does not do is decide which questions appear here or what the answers say; the affiliate disclosure sets out in full what does decide those things, and what would have to change for us to stop recommending a free step before a paid one.

What this site does not do

• It does not collect anything about you. There are no forms, no newsletter, no account, no cookies and no analytics. The privacy policy and cookie policy set out exactly what that means.
• It does not scan, check or diagnose your device, and no page here can tell whether anything is wrong with it.
• It does not publish testimonials, reader stories, star ratings or awards.
• It does not provide professional security advice, and it is not a substitute for a technician or for the ACSC. The terms say so formally.
• It does not claim any affiliation with the vendors whose products it describes, beyond the paid links that are disclosed.

Who publishes it

Getting in touch

If an answer here is wrong, out of date, or missing the question you actually had, the contact page explains how to reach the editorial team. There is no form — just an email address. We read what arrives and we correct what needs correcting, but we cannot look at an individual device or provide support for a specific machine, and the contact page is honest about that.
