on 5/25/08, suddenly got lots of threat alerts, checked anti virus etc think
it may have been disabled, don't know why. But system logs etc, now
warnings, e.g. rule "default block Bla Trojan horse" blocked (my address).
"your address has disappeared no longer protected" "port block allow
Netbios changed" Tried Netstat showing 7-8 no waiting. Looking at logs first
strange entries around 5/15/08
I am novice, never seen this before,need advice, scared.
thanks, hidecote,
 
sorry forgot to say I have used my anti virus to scan my computer for
threats. It shows ok. Can I assume my computer has kept the virus out?

Your post is very confusing since you didn't say from where you're getting
the threat alerts, which antivirus you're using, and what makes you think
it has been disabled. You should definitely make sure the machine is clean
by going through some scanning. I'll give you the steps below but since you
say you're a computer novice a better choice might be to take the machine
to a professional computer repair shop. Don't use your local equivalent of
BigComputerStore/GeekSquad. Get recommendations from family, friends, and
colleagues instead.

Go through these general malware removal steps systematically -

Include scanning with David Lipman's Multi_AV and follow instructions to do
all scans in Safe Mode. Please see the special Notes regarding using
Multi_AV in Vista.

When all else fails, get guided help. Choose one of the specialty forums
listed at the first link. Register and read its posting FAQ. You will
generally be asked to:

1. Download and execute HiJack This! (HJT) -
http://www.trendsecure.com/portal/en-US/threat_analytics/HJTInstall.exe

2. Disable Notepad's word wrap - In Notepad.exe; Format --> uncheck; "Word
wrap"

3. Download/run Deckard's System Scanner -
http://www.techsupportforum.com/sectools/Deckard/dss.exe

4. Save the scan results (Main.txt and Extra.txt)

5. And then post the contents of Main.txt and Extra.txt in your post at the
forum you chose. DO NOT POST LOGS IN THE MS NEWSGROUPS.

Standard disclaimer: I can't see and test your computer myself, so these are
just suggestions based on many years of being a professional computer tech;
suggestions based on what you've written. You should not take my
suggestions as a definitive diagnosis. If you can't do the work yourself
(and there is no shame in admitting this isn't your cup of tea), take the
machine to a professional computer repair shop (not your local equivalent
of BigComputerStore/GeekSquad). Please be aware that not all local shops
are skilled at removing malware and even if they are, your computer may be
so infested that Windows will need to be clean-installed. If possible, have
all your data backed up before you take the machine into a shop.

thanks, well I tried to keep the mesage short as advised. But I have Norton
security, and I didn't know the auto protect was off, on now of course. I've
completed 2 full scans since Sunday with Norton and it shows no virus
present, nothing to repair, etc. I have since found on the Norton threat
explorer that a low risk Trojan was discovered on 5/25/08, this is the new
bit for me, I think I can follow removal instructions but if the scan didn't
flag up any problem could trojan still be present? This was the only forum I
wanted to ask , sorry I maybe don't have the correct language but I am
grateful for help,

I would still scan with antispyware programs since Norton doesn't do that.
Start with Malwarebytes' Antimalware program since it is good,
non-invasive, and free.

thanks Jason and Malke. I had a good look at logs, event info, I now see I
have an annonymous login when I log in, next thing lots of policy changes re-
firewall, allowing exceptions. When i check windows firewall it has been
turned off. the login is event 540, type 3. Tonight I downloaded and ran the
malware prog. from the help and support centre. It didn't flag up any
malicious progs. Sorry but I'm still not sure if something has gotten
through into my computer or is trying hard to do so. I am new to this, it
does feel like I'm being stalked almost. I tried to run the IPSec monitor
snap-in but only could see it in the console of MMC could not get it to run.
Don't think I know enough yet. Sorry to go on, thanks for your interest.
Regards hidecote
 
To check everything properly, reboot your computer and tap F8 right at power
