F-Secure online scanner found the following trojan

Trojan.Win32.Dialer.q

C:\WINDOWS\Downloaded Program Files\1037639.exe

AntiVir X 1.21 seconds
Avast X 4.56 seconds
BitDefender X 2.83 seconds
ClamAV X 6.84 seconds
Dr.Web X 4.41 seconds
F-Prot Antivirus X 0.35 seconds
Kaspersky Anti-Virus Trojan.Win32.Dialer.q 4.18 seconds
mks_vir X 1.73 seconds
NOD32 X 2.50 seconds
Norman Virus Control X 2.17 seconds

i`m suprised avast did not find it.

How can i get rid of it?

Simply delete the file and update your Windows/ie . Do not use the IE for surfing “untrusted” sites.

i have already updates windows to SP2. I can`t find this file.

How can i find it, i tried searching for it,

Hi,

  • either delete it with the onlinescanner, or
  • search & delete it in safeMode (F8-Boot) or
  • search & delete it via IE-Options → general → settings → objects or
  • open a DOS-box and enter:

cd “C:\WINDOWS\Downloaded Program Files”
(the “” are essential)

then enter:
del 1037639.exe

:wink:

i opened up a command prompt window and typed:

cd “C:\WINDOWS\Downloaded Program Files”

but nothing happened, when i clicked on “find next”

plaese help

Hi Omar,

Firstly you must have found the file because you submited it to Jotti’s scanner as C:\WINDOWS\Downloaded Program Files\1037639.exe

I also noticed that only Kaspserky detected (Which will also be detected by F-secure on line as they use they share the same scan engine) and this file was missed by all the other vendors.

If you could locate the file that you sent in to Jottis scanner then resend to virus@asw.cz and I am sure Avast will add detection.

This is what F-seucre online says about trojans it can’t detect.

'4. How to remove malware that cannot be disinfected by OLS
F-Secure Online Scanner is able to remove viruses but it cannot disinfect Worms, Trojans, Backdoors, etc since there is nothing to disinfect. This type of malware needs to be removed manually from the hard drive.

Please see see more virus removal instructions from here: Link to virus removal page

Good luck in getting rid of it.

Kind Regards

Jlo

Since only Kaspersky and F-Prot (same scan engine) are finding it, this very well can be a false positive by them. Send the file in a password protected zip to virus@avast.com, support@f-prot.com and support@kaspersky.com let’s see what they say about it.

No did not sound like a false alarm. Folder(“O16” entries shown in hjt logs) and filename matches with some Dialer i saw last week.

Hi

the file that i have indicated, was copied and pasted directly from the f-secure online scanner-when the scan finished.

But when i looked in the downloaded files folder, that file was not there.

pehaps a hijackthis log would help:

i ran the f-secure scanner again, and it gives the following:

Finished: 1 virus found

Scanned files: 55217 Warning: 1 file(s) still infected!

C:\WINDOWS\Downloaded Program Files\1037639.exe Trojan.Win32.Dialer.q

C:\WINDOWS\Downloaded Program Files\1037639.exe Trojan.Win32.Dialer.q

Please use Escan: http://www.mwti.net/antivirus/free_utilities.asp it uses the same Engine F-secure uses(KAV engine reports that dialer). It will delete the file if it is still there. Please start the programm in windows safe mode.:

http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406?OpenDocument&src=sec_doc_nam

thanks, i`ll try it!

it did not find the trojan, don`t understand. How come f-secure finds it and nothing else does.

did I tell you to click on “find next” ?
don’t know what you mean anyway, but you should see this in the Command/DOS-Window:

C:\WINDOWS\Downloaded Program Files> and a blinking Prompt/cursor, right ?

  • if so, type there:
    DIR *.exe [ENTER]

what happens ? any filenames reported ?

-and what happens if you type :

DEL 1037639.exe [ENTER]

??

i see the flashing cursor, when i typed in:

DIR *.exe-it says:
volume in drive c is MT26G-4
volume serial number is 3C60-0F9F

directory of c:\documents and settings\omar khokhar

file not found

when i typed:
DEL 1037639.exe

it said, could not find:c\documents and settings\omar khokhar\1037639.exe

it has gone, i used killbox and deleted the file on reboot

I am new and confused. I run both avg and avast but not together.p I have zone alarm sybot and adware on my pc which is installed with xp home edition with svc pack 2 installed. i have scanned with both but i still have a trogan horse dropper small.6.L
C:\System volume Information-restore-{72D1485c-21cf-4604-BE39-68172DFC746E}RP661\A0012592.exe
that message comes up with avg resident shield which says to run avg i have run it and avast nothing shows up also when i run avast and it locates it in the boot scan i get an repair error 42060 message and all i can do is move the files got any ideas? thanks

3snookie, this is a false positive caused by system restore.

Disable system restore, reboot and the problem is solved.

sorry eddy i tried that after reading the posts and that has not worked any other ideas?

You must have done something wrong. This solution will work.
