I don't think malware is the cause of this problem.
Seeing that your laptop is not displaying the same symptom I am thinking it's not a modem/router issue. Nevertheless I guess you could try turning the modem off and back on again after waiting say 30 seconds to see if that makes a difference.
There is a repeated application error 0x80072ee7 showing in your logs.
Try the Fixit utility at the link below to see if that helps:

It is good security practice to change your passwords to all your online accounts on a fairly regular basis, this is especially true after an infection. Refer to this Microsoft article Strong passwords: How to create and use them.

Java warning
Java is a popular point of entry to your computer for malicous programs. The United States Department of Homeland Security recommends that computer users disable Java, see here. Unless you need it to run an important software the safest approach is to completely uninstall Java. Where you do require it, then the next safest option is to disable it in your browsers until you need it, then enable it.
How to disable Java in your web browser and How to unplug Java from the browser
If you do still need Java then regularly check that it is up to date. Older versions are the most vulnerable to malicious attack.
- Download Java for Windows
Reboot your computer.
You also need to unininstall older versions of Java.
- Click Start > Control Panel > Add or Remove Programs
