For past few days, getting occasional (few times per day) IP blocks to the same 2 IPs.
Yesterday and early this AM, I had Firefox 11 open to THIS website (MBAM forums) & to my home page (www.huffingtonpost.com):
18.104.22.168 (port 59615, process avp.exe)
22.214.171.124 (port 59617, process avp.exe)
I assumed it might be some ad content on huffpost, even though I run ABP and NoScript.
Just now, the only browser tab open was this MBAM forums page, so that eliminates huffpost as the source:
126.96.36.199 (port 58894, process avp.exe)
188.8.131.52 (port 589946, process avp.exe)
Blocks do not occur without browsers open, and have only started within the past day or so.
I can have a tab open for this website for several hours without a block occurring.
I noticed a similar block on my laptop a few days ago on the same sites, but assumed at the time it was also ad content on huffpost.
I have not powered up the system in a few days to re-evaluate if it's the same IPs.
Scans with MBAM, KIS2012 and SAS are all clean.
No symptoms of infection.
Both rigs are fully patched.
No new software or firefox extensions.
I am behind a hardware firewall, as well.
Will fire up the laptop to see if it's the same detections/blocks.
