Symantec Antivirus

and i suspect that the virus changed my registry which i think has disabled the liveupdate. does anyoen has any 'dictionary' on the registry? i mean registry listing n it's functions?

otyew,
There are a few versions of malware out there that will 'hijack' your web browser and prevent you from going to anti-virus websites.
One way around that is to do a 'tracert' of the web site 'name' you want, and then type in the IP address in your browser bar.
For example, Symantec/Norton updates can be obtained at: 192.168.1.254

Good Luck

I use this website (http://www.mvps.org/winhelp2002/hosts.htm) to replace the HOSTS file on every computer I repair.
Properly managing your HOSTS file should be a bedrock of security for every computer out there.

A side benefit is the exceptional speed up of connectivity to most websites - plus you can edit it to add the IP addresses of your personal 'Favorites'.

no, i can access to the internet but antivirus program unable to access to the server.

btw, how do i use the .bat program? i jus double-click it and it will restore everything back to normal?

Regarding this comment: "btw, how do i use the .bat program? i jus double-click it and it will restore everything back to normal?"
After you install the new HOSTS file (yes, by double-clicking the .bat file) you can open it with 'NOTEPAD' and look at how it is stuctured.
It is simply a listing of the most common IP addresses associated with the sites most frequented (prevents your computer from having to do a 'DNS Look-up' based on the web site Name). This really speeds up you browsing access.

It is also updated about once a month (you will receive an email notice) to identify and prevent access to known 'Bad Guy' sites out there.
Stick with this HOSTS concept and you will be truly putting a nice chunk of defense between you and the bad guys out there.

If you want to update your virus definitions to scan for the virus you can do thi manually by using Intelligent Updater from Symantec.  Here is the link:

http://www.symantec.com/avcenter/defs.download.html

This is usually a rather large file (approx. 13 mb) but it will update all of your definitions.

If antivirus cannot remove the threat, there are two utilities that you may find useful.  One is hijackthis:

http://www.majorgeeks.com/download3155.html

This Utility will show potential spyware, but be cautious, because it will also show you legitimate files and processes as well.

The other is MSCONFIG.  In windows XP you can type this command into the run dialoge and it will bring up a utility that will show what process and services are set to run at start up.  You can de-select any program that might be malicious.

Lastly, after you download the definitions you can go to symantec's site and search for the specific threat.  There will e a document on how to remove the threat on their site.

JamieRomness,
The problem with 'Hijacking' malware is that it "re-directs" any attempts to access Symantec (or any other AV/Security web-site).

If you Google the phrase "hijacked hosts file" you will find out a great deal about the process.

Good Luck,
Vic

the problem is the antivirus did not show any sign of virus attack when i manually update the virus definition. and then, i did not see any illegal processes at the back, i tried system mechanic to scan  but still nothing.

maybe i should try to use hijackthis program, and tell u all the outcome.

Yes, goos idea to post the HJT log:

Download and run HijackThis from http://www.hijackthis.de/
Copy-and-paste the resulting log back to that same web site (not here)
Click on "Analyze", and then click on "Save Analysis" at the bottom of the next page.
Finally post a link here to the saved analyzed page.

Before that, you may want to download and install lusetup.exe from http://www.symantec.com/techsupp/files/lu/lu.html and see if that fixes the Live Update problem.
