PHP2Shell (CVE-2026-109618): Is My Website Affected?
PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35, released on 21 October 2026, fix PHP2Shell, two critical flaws (CVE-2026-109618 and CVE-2026-109619) that can allow unauthenticated remote code execution on any PHP serving websites below those versions. On shared or managed hosting the host installs the fix; on your own server you update PHP and restart every worker. Check your PHP version in WordPress Site Health. Security vendors report exploitation attempts since 17 October; check your logs and files from that date. PHP 8.1 and older get no release from the PHP project, so ask your host. Updating PHP does not clean a hacked site or lift a blocklist flag.

Is unflagdomain Legit? What to Check Before You Pay
unflagdomain is a service of HUBtech s. r. o., a company in the Slovak Business Register since April 2025. Payment runs through Stripe Checkout, so card details go to Stripe, not to us. The price is €49 once per domain, refunded automatically if the re-scan after payment finds no flags. We guarantee that the removal requests go out within 48 hours; no one can guarantee a vendor's decision. Each point can be checked before you pay.

How Many VirusTotal Detections Is Bad? 1/70, 2/70, 3/70
VirusTotal produces no verdict of its own, so no number of detections is bad by itself. A ratio like 2/70 means two engines reported something: read their names. On a website, an engine that feeds browsers, antivirus web protection or firewalls blocks real visitors at any count. On a file, a low count can be a false positive or a very new sample. In our October 2026 report only 18% of flagged domains were flagged by a single vendor; the median was 6.

What Happens When Your Website Is Blacklisted? The Real Cost
About nine in ten browser security warnings end with the person turning back: 87% of malware warnings and 96% of phishing warnings in Google's Chrome data, and 77% to 96% across the published measurements we found. The flag does not lower your Google ranking by itself, but the hack behind it can. Google Ads disapproves ads to a hacked site, links in email get filtered, and firewalls and antivirus products block the site where you cannot see it. Listings are usually lifted only after the site is clean and someone asks.

WordPress Malware Keeps Coming Back? Where It Hides
WordPress malware keeps coming back because a hidden copy rebuilt the files you deleted, or because the entry point is still open. Look where file scanners do not: must-use plugins, drop-ins, an auto_prepend_file line, the database, cron, hidden admins and shared memory. Remove what is not a file first, then the files in one pass, and ask vendors to re-check only once it stays clean.

CVE-2026-87902: Was Your WordPress Site Already Hit?
WordPress 7.1.2 fixed a critical core flaw (CVE-2026-87902) that let an unauthenticated visitor include a local PHP file; attackers were probing for it within five hours, writing webshells through it the next day, and still at it a week later, with CISA listing it as actively exploited. Updating closes the door but does not tell you whether anyone walked through it first. Here is how to check your logs and files, what to remove, and why a blocklist flag can arrive weeks later.

Third-Party Script Got Your Site Blacklisted? Here's What to Do
When a third-party script is compromised, security vendors flag the domain that served it — not the company that shipped it. Remove what the attacker left behind, confirm the site is clean, then ask every flagging vendor to re-check it. In that order.
- Oct 13, 2026
Customers Say My Site Is Dangerous — Is It Hacked?
When customers say your website is dangerous, it usually means a security vendor blocklisted your domain — often after a hack or a false positive — though it can also be a quirk on the visitor's own device. Both are confirmable and fixable.
- Oct 13, 2026
Why Shared Hosting Gets Your Site Blacklisted
Shared hosting can get your clean site blacklisted when another site on the same IP gets hacked and security vendors flag the whole address. Check whether it's your IP or your domain, isolate from the bad neighbour, then request removal from each vendor.
- Oct 2, 2026
How to Stop Your Site Getting Blacklisted Again
To prevent a website blacklist from recurring, close the gap that caused the first flag: patch software fast, enforce strong logins and least-privilege, add monitoring, and keep clean off-site backups. Most reinfections trace back to the same unclosed hole.

Kaspersky False Positive Report (Website Flagged)
To report a Kaspersky false positive for a website, email the flagged URL and proof of cleanup to newvirus@kaspersky.com or submit it through the Kaspersky Threat Intelligence Portal. Reviews usually take a few business days.

Website Blacklist Removal Cost — What's Fair to Pay
Website blacklist removal costs nothing to nothing-but-your-time with DIY, €50+/month with agencies, or a one-time €49 with a pay-once tool. The vendor delisting itself is always free — you're paying for cleanup labor or the work of contacting each vendor.
- Sep 1, 2026
DIY vs. Done-For-You Blacklist Removal (Honest Comparison)
Doing it yourself is free but takes 3-10 hours of tedious work across dozens of vendors. A blacklist removal service saves that time by dispatching personalized requests for you, though no honest service can guarantee delisting since each vendor decides.
- Oct 13, 2026
How Long Does Blacklist Removal Take?
Every vendor runs its own review queue. Google says a review can take from a few days to a few weeks, McAfee averages 3–5 business days, and most antivirus vendors publish no time. In our re-checks, most listings were gone three days after the requests went out.
- Oct 13, 2026
Why Is My Domain Blacklisted? Common Causes
Your domain is blacklisted because a security vendor flagged it — most often after a hidden hack or injection, sometimes a false positive, a bad shared-hosting neighbour, spam activity, or a compromised email account. Each cause has its own fix path.
- Oct 13, 2026
Flagged Website vs. Flagged Download — Know the Difference
A flagged website blocks your domain or URL at the browser and reputation layer, while a flagged download blocks a specific file at the antivirus layer. They're separate problems with separate fixes — and unflagdomain handles only the website/URL kind.
- Oct 13, 2026
Google Red Warning on My Website: Why, and How to Remove It
A full-page red warning means Google Safe Browsing has flagged your domain as dangerous, so browsers block visitors before your site loads. Your site isn't deleted — it's labeled — and the label comes off once you clean the issue and request a review in Search Console.
- Oct 13, 2026
My Online Store Is Blocked — Emergency Guide for Shop Owners
If your online store is blocked, your site isn't deleted — a security vendor has flagged your domain and browsers are warning shoppers away. Clean the site, confirm what flagged you, then request review with each vendor to lift the block.

What to Do if Your Website Is Blacklisted (Full Playbook)
If your website is blacklisted, work through four steps in order: confirm which vendors flagged you, clean the root cause, request a review from each vendor separately, then monitor until every listing clears.

How Do I Know if My Website Has Been Hacked? (Signs)
You'll know your website's been hacked when you spot browser warnings, unfamiliar spam pages, sudden redirects, a traffic crash, or a notice from your host. Most hacks hide quietly, so checking proactively matters more than waiting for a crash.

Website Says “Not Secure” on Squarespace, Wix or GoDaddy — Fix It
A "Not Secure" warning on Squarespace, Wix, or GoDaddy almost always means free SSL just needs switching on — not that your site is hacked. Each platform includes a built-in certificate you enable in one setting.
- Aug 18, 2026
Why Does My WordPress Site Say “Not Secure”? (And How to Fix It)
A "Not Secure" label on your WordPress site almost always means a missing or expired SSL certificate, not a hack. Install a free certificate, force HTTPS, and clear mixed content to remove it.

URL Reputation Lookup — How Vendors Score Your Links
A URL reputation lookup checks how security vendors score your link — clean, suspicious, or malicious — using signals like malware history and phishing reports. Run one across multiple engines, since verdicts disagree and a single flag can block most of your visitors.
- Oct 2, 2026
Email Domain Reputation vs. Website Blocklisting
Email domain reputation decides whether your messages reach the inbox, while website blocklisting decides whether browsers warn visitors away. They're separate systems with separate vendors and separate fixes.
- Aug 7, 2026
Why Antivirus Flags Clean Websites (False Positives Explained)
Antivirus and URL scanners flag clean websites because they rely on heuristics and reputation signals, not just confirmed malware. New domains, shared hosting IPs, aggressive scripts, and outdated blocklist data all trigger false positives on safe sites.
- Oct 2, 2026
How to Clean a Hacked Website (Step by Step)
To clean a hacked website, take a backup, scan for malware, remove malicious files and database injections, patch the entry point, reset all credentials, then harden. Only after the site is verified clean should you request removal from security blocklists.

WordPress Hardening: Stop Malware Flags Coming Back
WordPress hardening stops malware flags from returning by closing the entry points attackers reuse: fast updates, two-factor login, no nulled plugins, a firewall, and clean off-site backups. Clean the infection first, then harden, then request delisting.

Avast Flagging Your Site as Phishing? How to Fix It

How to Check if Your Domain Is Blacklisted (5 Ways)
To check if your domain is blacklisted, use five methods: Google Safe Browsing status, a multi-vendor blacklist checker, email and IP blocklist lookups, Google Search Console, and individual vendor lookups. Each catches a different kind of flag.

- Jul 7, 2026
Is My IP Blacklisted, or My Domain? (The Difference)
An IP blacklist is an email problem — your mail server's reputation got listed on an RBL. A domain or website blocklist is a safety problem — Google Safe Browsing or antivirus flagged your site so browsers warn visitors. Different systems, different tools, different fixes.
- Jul 3, 2026
IP Address Blacklist Check, Explained
An IP address blacklist check tells you whether your mail server's IP is on a DNS-based blocklist (DNSBL) that filters spam. It's separate from a website blocklist check, which flags your domain for malware or phishing.

How to Check Your Domain Spam Score
A domain spam score is a 1–100% rating that estimates how spammy your domain looks to filters and search engines. Check it with a reputation tool, read the signals behind the number, then fix the links, content, and security issues driving it up.
- Jun 26, 2026
What Is Domain Reputation (and Why It Matters)
Domain reputation is the trust score browsers, security vendors, and email providers assign your domain based on its history and behavior. It splits into two kinds: site/security reputation (do you trigger blocklist warnings?) and email/sending reputation (do your messages reach the inbox?).

WordPress Malware Removal — Clean & Un-flag Your Site

VirusTotal False Positive: How to Report & Clear It
A VirusTotal false positive is when one or more of the roughly 70 security engines VirusTotal aggregates flags a clean website. VirusTotal itself doesn't delist anything — you dispute the flag with each engine that reported it.
- Oct 13, 2026
Deceptive Site Warning: What Each Red & Grey Warning Means
A deceptive site warning is the full-page red screen a browser shows when a security vendor — usually Google Safe Browsing — has flagged your domain. Chrome, Safari, Firefox, and Edge each word it differently. This guide maps every red and grey warning to its cause and its fix.

How to Remove “This Site May Be Hacked” From Google

Why Does My Website Say “Not Secure”? (And How to Fix It)
