Where are these IP packets coming from? (blocked by AntiVir)

I'll constantly get a pop up from Avira AntiVir Internet Security that its blocked an IP packet. Are these things dangerous? I'm doing a trial with the Internet Security package, and they pop up a lot that they're being blocked. I'm not exactly sure what they are or do, I don't have any spyware ro adware on my computer doing scans. I also made a note of the IP's as they popped up. Some will pop up constantly as the same number, some only seen once or so.

Do these pose any danger, and what do they originate from? Not necessarily the IP's themselves, but just IP packets in general. Thanks.

Below is a clean on
# Copyright (c) 1993-1999 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
#     rhino.acme.com          # source server
#     x.acme.com              # x client host       localhost

Thanks, mine looks exactly like that, so I'm still not understanding what the IP packets are (in general what is their use?) and where they're coming from. It continues to block them and I have no idea what their use is and haven't noticed any change whatsoever if they're being blocked or not.

. An ip packet is just a package of information sent via tcpip.
Proventia-Filter-Server is one of them.  = does not ping is unreachable
Server: denda6  =
pings but no site

download/run a quick scan of malwarebytes. http://malwarebytes.org/

I would also run an anti-malware scan.  It's possible a trojan or some other type of malware is installed on your computer and it's trying to communicate to the internet or try to download other files.  I would use a layered approach.  I would do like ccampbell15 said and download/run MalwareBytes.  I usually run the programs a couple of times so it removes everything.  I would also try a free online antivirus scan such as Panda http://www.pandasecurity.com/homeusers/solutions/activescan/.  Let us know what MalwareBytes and Panda finds.

Increase the security to highest level in your firewall to avoid such alerts in future. When you connect to Internet, its quite possible that a worm on some other computer on the internet is broadcasting and trying to find open ports to propogate to. Increasing the firewall security might help with that.

Do a scan with Avira in safe mode to help with any possible virus infections.

Hope that helps.

Thanks for the info, I'll try a few more times, but I've downloaded Malware Bytes and run to no detection, along with my Avira Antivirus scan I run each night, to no detection. Using WHOIS I identified the IP packets: AFRICAN NETWORK INFO CENTER INSIGHT SPRINTLINK GOOGLE GOOGLE UNIVERSITY OF  ILLINOIS CHICAGO INSIGHT

Insight is my cable company, so I emailed them asking what the packets were and pasted the IP's, and with University of Illinois I emailed them asking too, I have no idea what they were from. Using this WHOIS site helped a lot. The other IP addresses seemed to be a wide server range. http://www.networksolutions.com/whois/index.jsp

I just did a scan in GMER, I don't use IE but I changed the settings, so isn't a probem anyone. Nothing was flagged on GMER. These were the only files listed that I didn't even know where they came from. The rest were from AOL (for the AIM software), from Microsoft, or from Avira.

I think these are only system processes:

I'm beginning to think the IP packets were harmless, because running WHOIS lookups, some were common, and another IP I had listed I found belonged to Avira, and a couple other were from google. They seem to be sent out on web surfing.
