If Avira, Sophos, or Dr.Web is flagging your clean website, you fix it the same way for all three: clean the site if needed, then send each vendor a proper false-positive dispute through its own review channel. Once you've cleaned up, we email every flagging vendor for you for €39.

TL;DR: Avira, Sophos, and Dr.Web each run separate website blocklists with separate dispute channels. A cleaned-up or wrongly-flagged site stays blocked until you request a re-check from each one. Most vendors re-review within days. We dispatch a tailored request to every vendor flagging you for a one-time €39 — vendors decide the rest.

Why is my clean website flagged by Avira, Sophos, or Dr.Web?

Security vendors flag URLs they suspect of hosting malware, phishing, or hacked content — and they're cautious by design. Web attacks are common, and the vast majority of infected CMS sites Sucuri cleans run on WordPress (Sucuri Hacked Website Report, 2023). A false positive happens when their automated systems misread a clean site.

A false positive means your site is safe but a vendor's scanner decided otherwise. It happens after a recent cleanup that the vendor hasn't re-checked, after a shared-hosting neighbor got infected, or because a script, redirect, or download on your page tripped a heuristic. The block is real even though the threat isn't.

One thing to be clear about: this page is about website and URL flags, not flagged files. If Avira, Sophos, or Dr.Web is quarantining a downloaded program or .exe, that's a desktop antivirus detection — a different dispute process we don't handle. We work on domain and URL blocklists only.

Different vendors keep different lists, so you can be clean in one scanner and blocked in another. In our experience running unflag, the vendor you actually noticed — say, Sophos in a corporate firewall — is usually just one of several flagging the same domain. We scan across 124 active security vendors, so owners regularly see flags from engines they never knew existed. You can check where you're flagged with our free blacklist checker before doing anything else.

How do I dispute an Avira false positive on a website?

Avira reviews suspected false positives through its dedicated submission channel, where you report the URL and explain why it's safe. Avira's protection is bundled into Gen's consumer security products, which the company says protect hundreds of millions of users (Gen Digital, 2024) — so an Avira flag can reach a wide audience fast.

What you submit to Avira

You give Avira the exact URL being flagged and a short, honest description of the site and any cleanup you did. If the site was hacked, fix it first — submitting a dispute while malicious content is still live just gets you re-flagged on the next scan. Avira then re-checks and clears the entry if it agrees the detection was wrong.

There's no instant button. Like every vendor here, Avira runs the review on its own schedule, and the decision is theirs. What you control is sending a clear, correct request to the right place — which is exactly the part owners get stuck on when several vendors are involved.

How do I get Sophos to unblock my website?

Sophos handles website reclassification through its SophosLabs reputation lookup and dispute process, where you request a category review for a URL its web filtering has blocked. Sophos protects organizations in 150-plus countries (Sophos, 2024), so a Sophos block often shows up first inside a company network or firewall.

Why "Sophos website blocked" usually surfaces at work

Because Sophos sits in corporate web gateways and firewalls, the people who first hit your block are often a visitor's IT department, not the visitor. That makes Sophos flags quietly expensive — you lose B2B traffic without a warning page your own customers would mention. In our experience running unflag, owners often learn about a Sophos block only when a client casually mentions their office network won't open the site — by which point it has been live for a while. It's one reason we scan the web-blocklist vendors, not just the consumer antivirus engines, before you pay.

To clear it, you submit the URL for reclassification with a note that the site is clean or has been cleaned. Sophos re-evaluates the reputation and updates the category if it agrees. Again, the timeline and outcome are Sophos's to decide — we can't and won't promise a date.

How do I report a Dr.Web false positive for a website?

Dr.Web accepts false-positive reports through its dedicated submission form, where you send the flagged URL and request a re-analysis. Dr.Web, made by Russian vendor Doctor Web, has shipped antivirus software since 1992 (Doctor Web, 2024) and is widely used across Eastern Europe and CIS markets.

What Dr.Web needs from you

Submit the precise URL, confirm the site is clean, and briefly describe what it does. Dr.Web's analysts re-scan the address and remove it from their blocklist if they agree it's safe. As with Avira and Sophos, this is a website/URL review — not the separate flow for a quarantined file or installer.

Here's the pattern across all three vendors: same logic, three different forms, three different formats, three different inboxes. In our experience running unflag, a flagged domain is rarely flagged by just one vendor — it's usually listed by several at once, which is why doing this by hand turns into a multi-channel chase. Vendors like AVG and ESET only accept web forms, so we hand those back as guided dashboard cards rather than emails. You can see the full list of vendors we contact on our vendors page.

What's the fastest way to handle all three at once?

The fastest path is to clean the site first, then send every flagging vendor a correct request in parallel instead of one at a time. We do the dispatch part: for €39, one-time, we generate a tailored removal request for each vendor flagging your domain and send it, with your email as the reply-to address so vendor responses go straight to you.

What we do — and what we don't

We don't scan or clean malware. You handle cleanup (your host or a security plugin does that well), and we handle the tedious, multi-vendor request work afterward. Each email is written specifically for that vendor, sent over a one-hour window so it reads as genuine outreach, not a blast.

We guarantee dispatch, not delisting. We promise every flagging vendor gets a proper request, and we re-send if one bounces. Whether and when to lift the block is each vendor's own call — anyone promising "guaranteed removal" is overpromising. For Google specifically, Safe Browsing review is a manual step you complete in Search Console; we prepare the text, but Google's review can't be automated by anyone.
