Cant update windows or AV software

Postby bigfilsing » Wed, 04 Mar 2009 12:24 am

SInce about 4 or 5 weeks i can;t update windows anymore. Any attempt to go to the windows update page give me a google page.

My anti virus won't update anymore. I'm using AVG and have tried zone alarm as well.

I can update AVG via a seperate download but stil it doesn;t find anything worng whne doing a system scan. Could it be spyware ???

Any ideas guys

Cheers

suspect your PC is infected. a lot of smart virus do is to disable your AV.

check the following...

* system date, time and location are correct.

* disable system restore (in control panel / system)

* goto c:\windows\system32\driver\etc and open the filename hosts with notepad. the last line on your hosts file should not have any IP or domain name on it except for the localhost. the # is remark, so those are ignored. it should be nice and clean like this...

# 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:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

* also check your DNS and WINS. DNS should be on auto and nothing for WINS.


do the following...

you can get an online virus scan from trendmicro or symantec. also install antispyware/malware from www.superantispyware.com and www.malwarebytes.org.

Top stuff many thanks. Why i didn;t think of the DNS stuff is beyond me.

Turned out a piece of malware had control of my DNS settings. No matter how many times i manually reset it to the correct DNS the malware just changed it again.
No anti virus or firewall ( hard or soft picked this up !!!!)
Malwarebyts did the trick ...got rid of the lot and all is well. WIndows and AV updates now fine

Thanks
