Starting at 2:10AM this morning, I have a log of 15 attempts every 10 minutes or so that are triggering my malewarebytes.org.  Shows that it's an OUTBOUND attempt to cdn.skim.gs @ at various ports--none duplicated, just running them methodically--and that it's coming from my browser (firefox) and is being blocked.  Ran a malwarebytes.org scan, no issues noted.


I googled and am not finding anything that is helpful.  Searched this site as well.


Windows 8, up to date.  No other virus protection running on this box as I use programs for programming/design purposes that routinely get messed up with Norton or others.


Log file from Malwarebytes looks like this...repeated many many times with the port varying:


Detection, 9/10/2015 2:22 PM, SYSTEM, GATEWAYLAPTOP, Protection, Malicious Website Protection, Domain,, cdn.skim.gs, 59972, Outbound, C:\Program Files (x86)\Mozilla Firefox\firefox.exe,


Thoughts on next steps?


Browser is working just fine.  Not doing anything wonky.  All other programs are working well.

I'm getting periodic notices from Malwarebytes that skim.gs has been blocked when I access LiveJournal. Never on any other site. The popup box says:


Malicious Website Blocked

Domain: skim.gs


Port: 51213

Type: Outbound

Process: F:\Firefox\firefox.exe


I'm running Windows 7 Professional 64 bit SP1, with F-Secure Security Suite 16.0 Common Component Framework 2.44 Build 135. I have Malwarebytes Anti-Malware v2015.09.10.07 running. AMD FX-4100 Quad-core processor, 3.6 GHz, 8 GB RAM.


The most recent Malwarebytes scan log shows this line repeatedly:


Detection, 9/10/2015 12:01 AM, SYSTEM, LORRI-PC, Protection, Malicious Website Protection,

Domain,, skim.gs, 58080, Outbound, F:\Firefox\firefox.exe


I run Malwarebytes every day on my system, and a full scan using F-Secure once a week. What the heck is going on here? What is skim.gs? And why is my computer trying to contact them?
