Hello, I`m new here, and in the beginning I want to sorry for my English. i`m still learning.

Yesterday I`m noticed that i`m listed on 2 DNSBL lists. it`s cbl.abuseat.org and dyna.spamrats.com. I tried to remove my IP address from cbl.abuseat (i can`t do it on dyna.spamrats.), and it has worked. But today morning (about 24 hours later) i checked DNSBL and my IP again was listed on cbl.abuseat. I also noticed that svchost.exe process sometimes connects with strange ip address. it`s 93.184.220.29. I have read a little about this address, and it has bad opinions on this site " https://www.abuseipdb.com/check/93.184.220.29 ". Something about web spam, expoited host, DDoS Atack and more bad things. I scanned my computer with HitmanPro, Malwarebytes Anti Rootkit, Kaspersky TDSSKiller, Malicious Software Removal Tool by Microsoft, and Comodo antivirus, and nothing was found. My operating system is Windows 7 64, for security i use Comodo Internet Security Premium 10. Can someone help me and explain what`s happening? Why am I again listed on cbl.abuseat and what is the address 93.184.220.29?
Should I do any logs? 
Once again i want to sorry for my English. I hope you can understand my post.
Greetings.

Welcome to BC...

 

You could be part of a botnet. Sometimes whole blocks of IPs are black listed.

 

You can start a new topic in the malware removal forum. Since you have used most of the tools allowed in this forum, I suggest you do that

by following 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.

I just want to note that IPs of personal connections are often on DNSBLs because they are not supposed to be used for email servers.

Thank you for this information. I didn`t know about it. So there is a chance I`m not part of a botnet?

Just being on a DNSBL is not a sign of being part of a botnet. Some ISPs even report their IPs to DNSBLs themselves.

Hello,

Now that you have posted a log here: https://www.bleepingcomputer.com/forums/t/648955/botnet-infection/ 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 MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in 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 MRT 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 MRT Team members are EXTREMELY 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 MRT 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 MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

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. Good luck with your log.
