Hi everyone,

 

Starting 3 weeks ago I noticed I have to pass through a CAPCHA page before being allowed to access a bunch of webpages. My research led me to discover this is because my IP is listed on spam-catcher blacklists like projecthoneypot.org and abuseat.org. The latter, which hosts the CBL (Composite Blocking List) is also used by a bunch of other spam lists. It pointedly tells me that my IP is infected with the necurs spambot when my IP is queried.

 

Here is a screen shot: http://www.half-hp.net/uploads/Capturespambot5-12-2016.jpg

 

I am running Windows 10, and have Norton Internet Security and MBAM on my computer. Upon learning the news, the first thing I did was to scan with both softwares which turned up nothing. Later on, I've also downloaded and scanned with Panda AV, Spybot S&D and Norton Power Eraser. They did highlight a few things for me like my router password wasn't secure, the firmware was outdated, my Mozlla Thunderbird outdated.... which I've all addressed, along with minor suspicious file entries like PUP (which to me couldn't have been viruses...) and tracking cookies which I've all deleted.

 

Later, I realised I wasn't running a full scan with Norton (*face palm* it's default is a quick scan), so I did one. This time it found a "Trojan.gen.2" hidden in my secondary drive. This was deleted.

 

I've since re-ran MBAM, Norton Power Eraser, Spybot S&D, *and* MAcfee Rootkit Remover, TDSSKiller, and Malwarebytes Anti-Rootkit. All of which showed I have nothing.

 

Throughout this 3 weeks, the spam-catcher blacklist (particularly abuseat.org) continues to say I am infected with Necurs. I checked just an hour ago and my IP is still there.

 

Which should I trust? Online blacklists or AV/Malware programs?

 

Am I infected? What should I do?

 

I really appreciate anyone who can help me out.

 

:(

Welcome to BC...

 

It would be best for you to start a new topic in the malware removal forum by following the instructions below.

 

Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.

  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running FRST which will create two logs.

When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs...start the new topic anyway. Explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

After doing this, please reply back in this thread with a link to the new topic so we can close this one.

 

DO NOT bump your new topic. Wait for a response from one of the Team Members.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 5 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
