Post by: mauther on October 22, 2019, 10:08:46 PM
Avast is reporting this virus: JS: Downloader-FHO [Trj] (print below) on my blogger. I have tested with  several anti-viruses, including online and everything went negative. Can someone help me, please?

Hi Pondus & mauther,

I see nothing than the default index page: https://aw-snap.info/file-viewer/?protocol=not-secure&ref_sel=GSP2&ua_sel=ff&chk-cache=&fs=1&tgt=aF1zdFtuZ15sXXUjLn18XltuZw%3D%3D~enc
Nada - http://isithacked.com/check/http%3A%2F%2Fhostingcloud.racing%20

It is a general IP detection: https://www.virustotal.com/gui/url/44385784099f6c463f7a02e639ca884ed0c31d6f94e4f24abf63fc368545148e/detection

Reanalyzed results, but that is not a final verdict:

Final verdict should come from an avast team member, as they are the only ones to come and unblock under te present
situation of that website, as we here are volunteers with relative knowledge, but cannot come and unblock, just advise.

I take a look at the file below and I don`t find the lines at my blog html. Can you be more specific about where are located these lines, please?

Hello again,

Sorry for bothering you again, I spent several days racking my brains over this. Mr. jefferson sant instructed me to look for DOMusing developer tools  on the template, but what I found was that (image below). I could not find the malicious script in these lines. Can anyone help me?

Thanks in advance.

Hello for all,

 I have been blogging for almost ten years and it has always been a place of fraternization for paper model hobbyists, always free of charge. I have received several messages from friends warning about this infection and I myself feel slow to load the blog.

Thanks everyone for your support, but despite blogging all this time, I don't understand anything about scripts and things like this and I don't understand how to proceed: I can't find this line "Hostincloud.Racing", either in HTML or in the console of blog.

I don't know if it's allowed at this forum, but I'd like to know if anyone can be more specific about this line "Hostincloud.Racing" and how can I effectively visualize it?

Sorry for the bad English, thanks is advance and greetings from Brazil!

Mauther

You could ask Sucuri to help you, but it is not free  >>  https://sucuri.net/

Hello, Pondus,

I will contact Sucuri and see if I can afford this service. Thanks for the tip and greetings from Brazil!

Hello for all,

Just to close this thread, I would like to say that I contacted Sucuri, but the annual fee is prohibitive for me, since the blog is not for profit, just a hobby. So I decided to disable the blog so that the Trojan no longer affects any computer.

Many thanks to everyone here on the forum for all the tips and help. I learned some things that will help me in the future.

Greetings form Brazil!
