Site bloqueado pelo Avast - False Positive
« on: May 28, 2023, 02:18:41 PM »
O Avast está a bloquear o nosso website wxw.vagamundos.pt, alegando que está infetado com HTML:Script-inf[Susp]. Acreditamos que seja um falso positivo porque o nosso website é monitorizado 24/7 pela Sucuri (conta premium) e todos os relatórios indicam que está livre de malware.

Também verificámos em vários websites se existe algum vírus e todos eles mostram que o site não está infetado/blacklisted:

https://www.siteadvisor.com/sitereport.html?url=vagamundos.pt
https://yandex.com/safety/?url=vagamundos.pt&l10n=en
https://transparencyreport.google.com/safe-browsing/search?url=https:%2F%2Fwww.vagamundos.pt%2F

Já reportamos o false positive ao Avast faz dois dias em https://www.avast.com/false-positive-file-form.php, mas não recebemos qualquer feedback. Muitos leitores do nosso site estão a reportar que não conseguem aceder ao nosso website, o que está a prejudicar a imagem da nossa marca e os lucros da empresa.

Será que alguém aqui pode ajudar-nos a verificar este problema de falso positivo e ajudar-nos a desbloquear o site? Agradecemos imenso o vosso tempo.

This Securi scan does report some issues - https://sitecheck.sucuri.net/results/vagamundos.pt

Also some issues reported here - https://en.internet.nl/site/vagamundos.pt/2114908/

These may or may not contribute to the Avast detection, as an Avast user I can't say.

Thanks a lot for you help. Yes, the public Sucuri site shows the scan error but I have the premium account monitoring the site 24/7 and it shows no issues at all even at server side as you can see in the printscreen in attach. I´m also using Wordfence as firewall and all the scans show no warnings.

Honestly I believe it´s a false positive since, beside Avast, no more sites/software blacklisted our domain, including McAfee or Norton. Hope I can get some feedback from Avast soon because the blocking/virus warning is really damaging my business and brand reputation.

Yes, I see your screenshot, as it was in the link that you gave to labs.sucuri.net.  But I usually look at other sites, for clarification.

Whilst it is a weekend there would be a reduced number in the virus labs team, I would have hoped that they could still respond in a day or so.

EDIT: I see you also have a reply in the English section of the forum - https://forum.avast.com/index.php?topic=323872.msg1705040#msg1705040

Just to give some feedback: Avast team already confirmed that it was a false positive and cleared the reputation on their database and therefore the site is not blacklisted anymore. Thank you for the help.
