So, a few days ago I started receiving email notifications from my router letting me know about security alerts. I'm including recent logs from my router.

My network range is precisely 192.168.0.x, being my router 192.168.0.1

Does anyone know what's going on with my network? Am I infected with some sort of bot?

The address you see in the log belongs to the PC I'm using right now, I have all other devices turned off, including the wireless printers because they would also show being a source when they are on (the printers).

I'm going nuts here, please help.

Hello and welcome to Malwarebytes

If you think you are infected, here are the steps needed to get your computer cleaned....

Please read the following so that you can begin the cleaning process:

IMPORTANT: Don't use any temporary file cleaners unless requested - this can cause data loss and make recovery difficult

You have 3 Options that you can choose from as listed below:

• Option 1 —— Free Expert advice in the Malware Removal Forum
  
• Option 2 —— Paying customer -- Contact Support via email
  
• Option 3 —— Premium, Fee-Based Support

OPTION 1

As we don't deal with malware removal in the General Malwarebytes' Anti-Malware Forum, you need to start a topic in the

Malware Removal forum so a qualified helper can help you fix any malware related problems/infections you may have.

• Please read and follow the directions >>Right HERE<<, skipping any steps you are unable to complete.
  
• After posting your new post, make sure under options, you select Track this topic and choose Immediate Email Notification,
  so that you're alerted when someone has replied to your post.

NOTE: Please do not post back to (bump) your topic within the first 48 hours.

Replying to your own posts changes the post count and helpers are looking for topics with zero replies.

If you reply to your own post helpers may think that you're already being helped and thus overlook your post.

• If there is no reply from any experts after 48 hours, you can reply to the topic, asking for help again.
  Or
  
• You may send a Private Message to a Moderator asking for assistance.
  

OPTION 2

Alternatively, as a paying customer, you can contact the help desk by filling out the form located >>Right HERE<<

OPTION 3

If you would like to use our Malwarebytes Premium Services, Comprehensive solutions to all your computer support needs—from installation and set-up to troubleshooting and tune-ups go to our Malwarebytes Premium Services support site >>Right HERE<<

Please be patient, someone will assist you as soon as possible.

PS: Please use the "Reply to this Topic" or "More Reply Options" buttons (instead of the “Quote” and “MultiQuote” buttons) when replying here & at the other forums. That will make your topic easier to follow.
