Kill Messenger Service Pop Up

coffin

Hello,

I use Eudora as my e-mail client. When I view mail, sometimes, I get these pop-up windows that render, with the title bar reading "Messenger Service". There's the typical Spam garbage in the main area of the window and then an "Ok" button at the bottom. I simply just close the window. I'm using XP Pro. Is this Messenger Service part of the OS? Or do you think it's a pop-up ad coming in from an e-mail. Or, do you think it's part of some Spy Ware app? I just did a re-install of my OS and loaded on my primary software. I haven't downloaded any freeware or shareware apps that might contain spyware. These pop-ups just started.

Any ideas?

Thanks,

Jack

Messenger service is part of the OS. Its for sending messages to network users, from admins, things like warning them of downtime etc.

This basically means port 139 is open on your computer, and the spammers are using this to send you messages.

Basically, get a firewall, and make sure port 139 is closed or in stealth mode.

Have a look at the earler thread for more info 'DOS net send'.

Disbale messenger service.

In services

If you just disable the service, your computer is still open to much worse exploits, so its kinda pointless.

Block port 139, this will make you a lot more secure to net bios exploits.

ATM if you have shares with no password, anyone can access your files.

Thank you.

I disabled it in Services. I found a good link on how to do this:

disable messenger services

Thanks again,

Your computer is still open to loads of exploits, killing the service only stopped you getting the messages. Download zonealarm, or get a hardware firewall.

I cant tell you how easy it is to get access to your computer when this port is open.

dydx,

Thanks for the recommendation. I've been doing research on firewalls and routers (though routers don't offer as much protection as a good firewall). Linksys and Netgear, for routers, keep popping up with fairly decent reviews. I'll make sure it has SPI.

Do you have any recommendations?

Thanks.

As I've continued my research, I've found the SonicWall Tele3 TZX to be a pretty powerful product. It's pricey, though, at 500 bucks.

Any comments?

Thanks again,

For the time being, install zonealarm. Google it to find where to download it. Its free.

You can get decent protection from a router if you set up the port redirection correctly.

ie make port 139 redirect to port 139 on an ip that doesnt, and will never exist on your network. This will make the port look closed to an attacker.

A good way to test the security of your computer is at http://www.grc.com head over to the sheilds up thinger over there to see how your doing.

dydx,

Thank you again for your recommendations. I'd like to get further advice from you.

I've downloaded zonealarm. In the future, would you recommend a hardware firewall (or router) over a software firewall like zonealarm? Or should I consider using both?

Thanks again, too, for the grc.com recommendation. It's first report, before zonealarm, was pretty frightening.

I use a standard router as a firewall.

Zonealarm is pretty crappy, but it beats getting your computer screwed up by some lamer.

stoopid

I use an older Linksys router and cheap dlink switch, but a switching linksys or netgear router would work fine in this scenerio.

Also, don't be too paranoid about internet security, 'cause if someone with the skills REALLY wants in, there isn't a heck of a lot you're going to do to stop them... the firewall's to keep the 14 years olds, practicing with hacking guides, that could make a mistake and actually hack you

if you have a spare computer sitting around, i recommend www.clarkconnect.org it's a linux distribution specifically made to be a router/firewall, as well as a host of other services. you configure it through a browser, so you don't have to know any linux commands. i've been singing it's praises for years now.

dydx

Those Linux distros for making routers are great. I used SmoothWall for a while before I got my router.

I ran it on a Dell 486 66MHz with 32mb of RAM, and it was pretty good.

An easier option is Freesco, which boots off a disk, and its a bit simpler.

Thank you everyone for your advice. I really appreciate it.

Off to get a router today.

Thanks, kanezfan, for the clarconnect.org recommendation. Sounds interesting and I'm going to check it out.

There is a decent firewall called Sygate Professional also. In fact, look on thier site at the organizations that endorse and have tested it. Even Sygate Personal is very decent and uses less computer resources than ZA.

A lot of people who have not tried this seem to thnk it cannot be that this is bettr than ZA, but it has proven to be equal to or better than ZA and use less of your computer resources.
