Hi!
I'm afraid my PC has a trojan or virus on it!

Symptoms:
GRC ShieldsUp and Symantec scanner show port 1723 (pptp) open, whilst all others I can test are stealthed. I have found little on the internet about this port, but it seems it has been used by malware.

Since then, I have activated certain security auditing functions, and have seen a number of events (ANONYMOUS USER logon, IPsec failed to get complete list...,) logged. But I can't really interpret most of them!!

I'm running updated Norton IS 2005, and have set a rule to block communication on port 1723 (but the port is still open). I see no indications of use of the port in any logs I've looked at, but I'm no expert. So I attach a HijackThis file and ask for any help anyone can give.....

Some background (system protected by Norton IS 2005, Pest Patrol, SpyBot, all up-to-date) :
A few days ago the system disk crashed after the PC beeped and locked up during surfing. I couldn't get XP SP1 to run again, and there were errors in the partition table (may have in part come from Ghost, Partition Magic, Maxblastor some other program, since the disk had been in use a long time). Relacing the system disk, I could read the two partitions I had so could save the data. Reinstalling XP (with new partitions) would not work - eventually I had to fully repartition and delete all partitions (Partition Magic) and then I could reinstall XP SP1. Then downloaded and installed SP2 and other updates. Things seemed ok. But just to check......
Antivirus and other scans revealed notheing untoward. Doing the port scan, however, I found the PPTP port 1723 open! And that seems dangerous to me!

Looking forward to any replies

Hello, Lonny:

First, thanks for your reply to my problem with having port 1723 open. Unfortunately I have been tied up with other things, so it has taken me a while to try your suggestions.

So the results:

* ran Kapersky online: nothing

* ran panda active: nothing

* ran tenrdmicro: nothing

* ran bitdefender: this found 8 suspicious files - but it got lost in /systemvolumeinfo: 19 h to do and rising; so I had to abort this, but afterwards bitdefender didn't indicate which 8 files it had deleted; re-running found nothing. Also nothing after switching off system restore and rebooting. Subsequent error messages indicate that the missing files MAY include mscoree.dlll and mapi32.dll.

Regular use of other programmes such as adaware and spybot have revealed nothing untoward.

The machine generally seems to be behaving itself and is running smoothly, except.....

Except that port 1723 is still open!

And:
I am getting warnings (usually just on startup or shortly thereafter) from the Symantec Resource protector that protected Norton files are being accessed by, variously, winlogon.exe, thguard.exe and other files, and recently only ppactiveprotection.exe (PestPAtrol). I am in touch with Symantec technical service, but so far, although they respond promptly and friendly, seem unprepared to really address my problem (they don"t comment on port probes; can't respond when a German Norton is running on an English XPPro (?!),....).

So I am really quite lost and confused!? Maybe there's nothing wrong...
Any suggestions you or anyone else might offer would be appreciated (yours is the only response that has so far been of any help!).

Thanks+regards

Haller

Hi

Where on gibsons web site did a scan show results for port 1723 ?
Normaly its probes 0 - 1055

I think your seeing a false alarm

""Subsequent error messages indicate that the missing files MAY include mscoree.dlll and mapi32.dll.""

Can you explain that further please ?

Hi, Lonny:

The GRC site where I did the port probe is on:

https://www.grc.com/x/ne.dll?rh1dkyd2

The particular port range has to be specified (I think it was the other scanner that picked up that it was open - then I checked specifically using GRC).

Concerning the missing files:
Norton 1button-checkup found a false entry for mscoree.dll (missing file), and on booting, mapi32.dll could not be found. But since then I've had no more error messages.

I have further checked the PC with the rootkit searcher, Blacklight from F-portect. Fortunately it also found nothing.

So it may be that I am reacting to false alarms. But I would still like to get confirmation from some expert source that this is indeed the case.

Thanks again for your input
