I noticed all of a sudden my cable modem is running like crazy even when i have no traffic...looking at my router logs I see ALOT of this:

Blocked outgoing ICMP packet (ICMP type 3) from 192.168.0.196 to 24.14.254.19


Tracing that IP its going to is a comcast.net domain I have another just like it that is going to a qwest domain different ip. Virus scan shows clean but this seems like rootkit or am I wrong?

From experts exchange:

"ICMP can't be used to transfer data... it's most likely due to network scanners on computers attempting to ping you... the ICMP type 3 indicates that the router is sending back "destination host unreachable" and unfortunately you can't stop that kind of traffic coming in, as long as your firewall is good and your network is protected then there is nothing to worry about with this kind of traffic."

You should have more problems than router traffic if a rootkit/virus is on the computer, however some can infect a router.

Go online a find the directions to reset your router or re-address it and see if that helps.

That does sound like rootkit/virus files.

Please download Malwarebytes' Anti-Malware from one of these sites:

MalwareBytes1

MalwareBytes2

Rename the setup file, mbam-setup.exe, before you download it. To do that once the "enter name of file to save to" box appears as the download begins in the filename box rename mbam-setup.exe to tool.exe> click save.

1. Double Click tool.exe to install the application.
2. Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
3. If an update is found, it will download and install the latest version.
4. Once the program has loaded, select "Perform Quick Scan", then click Scan. The scan may take some time to finish,so please be patient.
5. When the scan is complete, click OK, then Show Results to view the results.
6. Make sure that everything found is checked, and click Remove Selected.
7. When disinfection is completed, a log will open in Notepad and you may be prompted to Restart. If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediately.
8. The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
9. Copy&Paste the entire report in your next reply.

Please save this file to your desktop. Win32kDiag.exe

Please double click on the Win32kDiag file and post the log it produces. This log might be quite lengthy and may take more than one post to get all of it posted.

That does make a difference as many of the tools used to find and kill baddies will not work on a x64 system.

Please download OTL from following site:

Link1

1. Save it to your desktop
2. Double click the OTL icon on your desktop.
3. Click the “scan all users” checkbox.
4. Push the “run scan” button.
5. Two reports will open, copy and paste them in a reply here:
OTL.txt <-- Will be opened
Extra.txt <-- Will be minimized
