What is TROJAN HORSE CONSTRUCTOR.CJA?

davidmcg2u

Hi guys,

My PC seems to be running smoothly but my AVG scan has picked up the following:

TROJAN HORSE CONSTRUCTOR.CJA

It has shown 3 times in the following files:

C:\DELL\MEDIAEXE\ONDRVMED.BIN
then
C:\DELL\MEDIAEXE\ONDRVMED.BIN\Media\SUPPORT\TOOLS\SUPPORT.CAB
then
same as above but with :\bitsadmin.exe on the end

Can anyone tell me what these are & what I should do.

Thanks

bitsadmin is part of Windows SP2
it's a support tool

suspect a false positive

Somebody else is reporting it on the AVG forums so it looks like Browntoa is correct:

What is the best way to deal with suspected FP's ? I see AVG has a procedure but there are a few negative responses to it

Im not so sure of it being a 'false' positive. Its a 'back up' file which is what a lot of trojans like to 'stick to'.

double check by running this free online scanner

Yes got the same 3 Trojans !! running AVG and found on a scan and unable to put into the virus vault as to large .
Reluctant to do anything with it until it is confirmed that it is a false positive

Dont panic
Just dont use Dells support for now until its determined whats going on.
In fact if you can. Run CCleaner

Goto TOOLS and START UP and see if you can disable it from running

I too have the same 3 trojans and I cannot send them to the virus vault as the files are too large. Is it safe to use my pc or should I wait until they have been confirmed as false positives, if indeed they are? How can I make my pc safe? Last time I had to wait over a week for a reply from technical support.

I ran AVG yesterday with the same consequence.
There doesn't seem much info on what this is!

If theres 3 of you SUDDENLY have it ~ then its probably a false positive
OR
Someone somewhere is using dell computers to unleash his trojan!
Now I have a Dell ~ but its Vista, and that folder does NOT exist on mine.
Is everyone on XP?

If you want to lock it
goto AVG
TOOLS
MAINTENANCE
VIRUS VAULT
and ramp up the vaults size
