Since installing Norton System, Works and re-installing HP1200 Printer/Scanner I am experiencing the following problems
1. When connected top the internet I hjave a maximumof 9 minutes before I get a message giving me notgice to close down all programmes before a "Restart" The message is "NT AUTHORITY\SYSTYEM" it identifies the problem as being - Windows System32/lsass.exe I repaired it and when I next accessed the internet the same thing happened again. I have repaired it several times and it still occurs

I have also done numerous system restores to solve the problem but it continues to plague me

The anti virus programme has been run and nothing’s a problem there

I also find when I open Outlook I cannot download e-mails unless I disable the Norton Internet Security programme

This message has been sent from a different machine otherwise I would have sent down by now
 
Hi William,

First of all, I recommend against posting here with a valid email address,
as a worm called W32/Swen harvests email addresses from these groups and
spams people with them.

You are infected with W32/Sasser.worm or its variant, W32/Sasser.worm.b.

The first step to take is to update your machine with the latest patches.
You can do this at the following site:

http://windowsupdate.microsoft.com/

Then, you need to remove the worm. This can be accomplished using McAfee's
Stinger program. Stinger can be downloaded here:

Next, you should get a good antivirus program. You can find a free program
called AVG here:

Last but not least, turn on the firewall that comes with your Windows
installation. If you do not have Windows XP, you can get ZoneAlarm, a free
firewall, here:

http://www.zonealarm.com/

This, along with frequent Windows Updates, should prevent future infection.

Hope this helps. Feel free to post back if you need any more assistance.

Sincerely,

Congratulations! You have a virus!

There are removal instructions there for both versions (including tools to
help you.)
Know that even if you have the normal updates for Norton, the definitions
for "B" were added on May 1. You can go to Symantec's site and get the
manual update if you like.

My other suggestions to you include:

Please Notice that if you use AOL, you should at least upgrade to 9.0 or
greater before doing any of the fixes. I know you can get AOL 9.0 at almost
any convenience store, gas station, super market or other retail outlet in
the world, so this should not be a problem.


Turn on that firewall...

(It has been reported that it now works with AOL 9.0+)


Make sure you have all the updates (critical) installed from:
http://windowsupdate.microsoft.com/
(Scan for updates, Review and Install)


Get rid of the spy/ad/mal-ware..
(Yes - using MORE than one of these..
I recommend at least the first three. Also..
UPDATE the definitions for them before using.)

Spybot Search and Destroy

Lavasoft AdAware

Hijack This!

I also like "The Cleaner" and "SpywareBlaster" and "SpywareGuard".
- http://www.moosoft.com/
- http://www.javacoolsoftware.com/

The first is a PAY product, but useable for 30 days - it has found and
eliminated problems in the past the others did not. The latter two are
prevention mechanisms. I like SpywareGuard for those with enough processor
to have something running like antivirus software - and it prevents browser
hijacking quite well. SpywareBlaster is a FANTASTIC free product, I suggest
getting this after you cleanup and keeping it updated as well....

And Assortment of Others:
http://spywareinfo.com/


After you cleanup your PC somewhat of spy/ad/mal-ware, verify your antivirus
software is updated and run a full scan of your computer. If you have no
antivirus software - get one NOW! Grisoft AntiVirus:

Empty your Temporary Internet Files and shrink the size it stores to about
80 to 120MB (seems to be an optimal size for the normal user)

- Open ONE copy of Internet Explorer.
- Select TOOLS -> Internet Options.
- Under the General tab in the "Temporary Internet Files" section,
do the following:
- Click on "Delete Cookies" (click OK)
- Click on "Settings" and change the
"Amount of disk space to use:" to something between 80MB
and 120MB. (Betting it is MUCH larger right now.)
- Click OK.
- Click on "Delete Files" and select to
"Delete all offline contents" (the checkbox) and click
OK. (If you had a LOT, this could take 2-10 minutes or
more.)
- Once it is done, click OK, close Internet Explorer
- Re-open Internet Explorer.


Uninstall any software you do not use often/ever. (If you have something
installed but never use it, uninstall it.) If you go through Control
Panel -> Add/Remove Programs and see things you seldom if ever use, it is to
your advantage to remove it.


Also, if you are tired of Web Page Pop-Ups/Unders.. You could try the
Google Toolbar.
http://toolbar.google.com/


Stop loading applications at logon.. run MSCONFIG and look under the startup
tab for things you DON'T want to startup! Search the Internet with Google
to discover what things are safe to remove and what things may even be
malware infecting your computer.
