Surfing speed dramatically reduced about 3 days ago. Installed ad-aware and Spybot 'Search and Destroy' to try and speed things up a bit. Do have Norton Antivirus and Personal Firewall 2002, but used free scan from antivirus.com to double check. Trojan dyfuca.b identified as resident on PC, don't know how to get rid, any guidance greatly appreciated. Many thanks in advance...

Hi 6aardvark9 Wave.gif

Ouch! You have no windows updates installed? I should see at least SP1 on both Windows XP and IE 6. We'll need to get you to do that or the odds of you getting infected right away again is very high.

But first, there is a dailler program on there we need to take care of.

1. Please go offline, close all browsers and any open Windows, making sure that only HijackThis is open. Scan and when it finishes, put an x in the boxes next to these items, then press *fix checked*

O4 - HKLM\..\Run: [blacksex.exe] c:\Program Files\DiallerProgram\014192.exe -r


2. Make sure your PC is configured to show hidden files

Open Windows Explorer & Go to Tools > Folder Options. Click on the View tab and make sure that "Show hidden files and folders" is checked. Also uncheck "Hide protected operating system files" and untick "hide extensions for known file types" . Now click "Apply to all folders"
Click "Apply" then "OK"

3. Reboot your PC into SAFE MODE

How to start the computer in Safe mode
http://service1.symantec.com/SUPPORT/tsgen...src=sec_doc_nam

Search for and delete the following folder named in bold:

c:\Program Files\DiallerProgram

4. Reboot your PC back into normal mode

5. Go to Windows Update and get ALL the critical security updates recommended for your system:

http://v4.windowsupdate.microsoft.com/en/default.asp

I'm not sure that will resolve your problem as there were some Norton customers experiencing problems a few days ago with an update causing slow downs. Let us know if that does resolve your problem or not. And if not, I'll see what more information I can find on it for you. :)
6aardvark9
Thanks Calamity :)

I could have sworn that I had downloaded SP1, but maybe (and apparently) not! Followed your advice, but unfortunately I have no subsequent improvement in performance.

The slow-down does however coincide with a recent large update from Symantec, which may or may not be relevant.

Still have the dyfuca.b resident, which I cannot shift at present.

Attached is latest hyjackthis file... thanks for your support!

6aardvark9, good morning :)

Your log looks good now. The dialer is gone and I see you got the Windows updates. :thumb:

What details does NAV give you? Precisely what is the file name and exact location (full path) for the infected file.

There were several discussions in a number of forums I visit on the NAV slowdowns regarding a Redirector update and problems at Akamai. This was one of them.
http://www.dslreports.com/forum/remark,10312609~mode=flat
CalamityJane
Here is another thread I ran across describing the problems with NAV 2002 users - seems similar to your issue so the slowness may be a Symantec problem?

sudden slow browsing - CPU flat out
http://www.dslreports.com/forum/remark,10283362~mode=flat
6aardvark9
Hi Calamity ahah.gif

Many thanks for the info regarding NAV slowdown problems, I'll have a good read when I get a chance tomorrow.

Unfortunately NAV 2002 does not identify the dyfuca.b virus at all, and gives my PC a clean bill of health. I have used HouseCall from Trend Micro, free on-line scan, which has identified the problem.

The problem file is mapped as follows:

C:\system volume information\_restore{11B4CBB0-31B0-483C-A4FE-D6E9E8C1A928}\RP15\A0001079.dll

In order to remove the virus, Trend recommend editing the registry to remove specified malware registry entries, but when I looked there were no entries as detailed within Trend's recommendation. HouseCall is also unable to remove the virus.

Hope this helps you to look a little deeper!

Many thanks for your continuing interest and kind assistance.

Cheers,

6aardvark9
CalamityJane
Ah Ha! Thanks for the additional info. This probably won't help the slow down problem, but here is how to get rid of the virus alerts :)

C:\system volume information\_restore{11B4CBB0-31B0-483C-A4FE-D6E9E8C1A928}\RP15\A0001079.dll

That is your system restore backups and is very easy to fix.

Sometimes, when a PC is infected a copy of the file is backed up in your System Restore (XP and ME). By default, Windows prevents System Restore from being modified by outside programs, which includes your AV program.

See here for how to reset your System restore to resolve the problem

Cannot repair, quarantine, or delete a virus found in the _RESTORE or System volume information folder
http://service1.symantec.com/SUPPORT/nav.n...000092513515106

Turn it off - reboot - turn it back on. :thumb: That will clear the problem
6aardvark9
Hi Calamity :thumb: ,

Thanks for all the advice...I'm now virus free, but still lacking browsing speed.

The threads forwarded regarding Redirector Update problems with NPF have convinced me that this is the root of the problem, and the Trojan was just an aside!!

On the down-side, I can't go back to a system restore prior to the Live-Update which has caused all my grief since I have wiped them all removing the remants of dyfuca.b

On the up-side, I contacted Symantec and negotiated an acceptable discount on the upgrade price for NIS, based upon my current NPF and NAV subscriptions. Still more than I should have to fork out, but I suppose I'll get the added benefit of blocking pop-ups!! Besides, I seriously miss the speed, I feel like an Internet cripple with a 286 machine and 28 kps modem that has been run over by a bus.

This forum has proved to be invaluable, and for that I thank you.

Until the next crisis.....

Cheers,
