Win32/Sorin.A Worm

Nod keeps detecting this worm in the wild, however when I do a system scan it detects nothing. I have been having small probs with my sys for a week or so which indicates something is there......
I can find no reference to this worm on any official Nod sites....does anyone know anything about this little bugger...am I going to have to reformat and start again to get rid of it...........

Any help appreciated muchly...

 

Simple answer is no, I would slave your drive off a clean protected system and have it scan your infected drive, to see if anything is there, I'd also run it through a second virus program using the same method just to be sure...

Nod has been detecting it since v.1.454 (20030707) see http://www.nod32.com/support/info.htm

Hope this helps.

Cheers

 

Hi Lusid,

Can you tell me some more about this, what kind of probs.

How can you be sure you have that particular worm on your system.

What are the symtons??

rgds,
Martin

 

Small probs is a bit vague I know..........it's just that there is nothing going wrong persay..........it's more like my system is very 'sticky'.

I don't have the fastest of systems anyway, but I really notice when things slow down.

Let me explain. Probs seemed to start after a LAN night. All persons present were using Norton 2003 at the time, after that night a few guys started having probs with system lockups etc...assuming it was Norton (as it is huge, and very invasive) a few of us ditched Norton in favour of Nod or Vet.

With my system, it started detecting the Sorin.A worm, here and there, usually it could clean or delet no probs, then all of a sudden a few popped up that could not be deleted or renamed or anything.

I wasn't too worried as I understand that if it's detected it hasn't made it into my system, I was told the antivirus 'locks' the file so it can't go anywhere.

The only specific prob I've had that I can pinpoint is quite often I leave my PC running overnight to download large files (only 56k dial up) when I get up to check it in the morning the Virus detected screen is up telling me that it detected Sorin.A.

It appears that my internet connection whilst still showing as active, is locked out as my download manager is no longer able to find the files and any attempt to browse is met with domain errors..

Also, the indications are that the file is being 'restored' by my system, thus I have disabled the restore function temporarily to see if that may fix the prob.

Meanwhile I have got another AV program and will try the other suggestion above...

Hope this makes sense, if not try MSN or email me

Hi Lusid,

Can you dodwnload Spybot and run the prog.
see what it comes up with.

Download :

http://www.wilders.org/HTMLobj-1590/spybotsd12.exe

While your at it download HijackThis, it will let you show what's happening in your registry at startup, please copy it and post it.

Dowload:

http://www.tomcoyote.org/hjt/

Let me know oké,

rgds,
Martin

 

Are you using a firewall?

 

Martin - I'll download that stuff and then post the results......

Blackspear - yes, I have ZoneAlarm Pro, I don't think that's causing any dramas though because I have had that for ages and probs are only very recent......

disabling the restore functions may have done the trick, left it on all last night without any virus detections or interruptions to downloading....fingers crossed

Guys, thanks heaps for your help so far, will post again tomorrow...

 

Maritn, downloaded those appz, spybot is a nice littel gem, it found 13 nasties lurking on my system, they are now dead!!!

Now you wanted me to post the stuff from hijackthis, two lists compiled and here they are....................
bloody long lists they are

Hope this makes sense to you because I'm a little confused by it all....after 5 years trying to keep up I thought I was finally learning something............and I have, I now know enough to know what I don't know.....

I will be offline for the next few days, taking a trip up to the big smoke so wifey can go to hospital for a minor op, will check back in a couple of days....Thanks............LuSiD
