RANDOM broken internet access.. PLEASE HELP!

I have a stable cable internet connection and have for years. Recently, it started going out at random times quite often. I figured it was my provider, but as it continued for days I grew suspicious. It seems like from 11 PM on I barely ever even get a minute of service, but in the day it isn't as bad. However, my ISP is actually working well and I have great connection.

A recent HiJackThis log showed a possible cause: I had the Bonjour folder installed by Itunes, and it was missing a file. It recommended LSPfix, which I ran. Nothing changed. After some google searches about similar problems, I also tried WinsockXPFix.

Still, my internet will work one second and be out the next. HijackThis no longer shows any problems for Bonjour, and LSPfix wont come up with any errors. I don't understand what is wrong, but it must be serious.

Any ideas? I appreciate it.

 

I finally fixed the program by scanning my PC again with TrendMicro. I hadn't done so in a few days, and it picked up a Trojan Klob virus. Apparently this was the problem. Thanks though!

 

Actually, the problem is still continuing. However, it seems to be a bit better than before. I tried the Read & Run me, but still no success.

I am using a hardwired Cable connection

 

I also would like to add that the internet only cuts out lately from about midnight through around 4 am when I give up on it. It seems like during the day it runs fine (though maybe not as fast as it used to).

 

I still have to gather the rest of the logs because I hadn't saved them originally (I admit I didn't follow instructions very well at first), but here is the long from Malwarebytes
