Solve : Is this a virus or a trojan or something??

Answer»

Hi....

I see "rundll32.exe C:\WINDOWS\system32\drvriw.dll,startup" ---> it's something like this sometimes it;'s drvriw.dll, or drvrph or something else similar and there is also something to do with MSDisp32 on my computer.

I deleted the referencing startup entry from system startup using CCleaner and problem seems to go away. Another time I started computer, similar problem appear. Problem doesn't occur every boot but it happens now and then so I wonder what's going on

I wonder how to fix this problem? I used malwarebyte's antimalware and AVG 8.0 free on my computer and have deleted all problematic things both have discovered.

----------------------------------------

Windows Vista w/ SP1
AVG8.0 free installed, updated.
Malwarebyte's AntiMalware free version updated.
Windows Firewall enabled --> I would be using Commodo firewall but I didn't like all the popups that tell me to approve/block some new software or process.



Thanks!


Download and rename TrendMicro HijackThis.exe (HJT)

  • Double-click on HJTInstall.
  • Click on the Install button.
  • It will automatically place HJT in C:\Program Files\TrendMicro\HijackThis\HijackThis.exe.
  • Upon install, HijackThis should open for you.
  • Close HijackThis and rename it.
  • Go to C:\Program Files\Trend Micro\HijackThis.exe
  • Right click on HijackThis.exe and select Rename.
  • Type in sniper.exe and press Enter.
  • Right-click on sniper.exe and select Send To > Desktop (create shortcut)
  • From the desktop open Hijackthis.
  • If using Windows Vista, Right-click and Run As Administrator.
  • Click on the Do a system scan and save a log file button
  • Hijackthis will scan and then a log will open in notepad.
  • Copy and then paste the entire contents of the log in your post.
  • Do not have Hijackthis fix anything yet. Most of what it finds will be harmless or even required.
Although we have renamed Hijackthis to sniper, we will still refer to it as Hijackthis or HJT.
Hi evilfantasy ....

I posted HJT log so please check it. I hope my computer is all clean now so that I may go about doing what I was doing

MBAM log
A NEW Hijackthis log
1. I booted my computer a few minutes ago and I see some drvbock.dll detected by AVG and AVG says it's a possible unwanted program or something like that and I pressed move to vault.

2. ok. I have done the Hijackthis system scan. Both entries you mentioned existed, so I fixed all as you recommended.

3. I have done the CCleaner cleanup.

4. I have not yet done the Malwarebyte check.... will do that later.



I'm moving this to the Computer viruses and spyware forum.

drvbock.dll is an unknown virus which is why AVG isn't fixing it. If MBAM doesn't get it we will go to more powerful tools.

Don't worry, we'll get it!!! I scanned with spybot S&D program and I see MSDSip registry entries detected under VIRTUMONDE error.

I will double check TOMORROW with the MBAM program and also with Spybot. Spybot said some of the virtumonde errors can't be fixed as they are detected to be in use in the memory and now I have to restart and have Spybot scan and clean before computer loads otherwise it might fail again.

Also, like I said, drvbock.dll came up this time. drvriw.dll came up last time and if this problem still goes on, it might report a different dll is problematic.

I think AVG isn't fixing the dll problems. But it knows it's problematic which is why i think the dll can't run error comes up-- AVG blocks it. Without following through on my instructions we will end up making this a very long process when it doesn't need to be.

You'll notice that with every step I request it produces a log to be posted. Without "seeing" whats going on it's all just debate and guess work. I have to find the location of the infected file(s) to be able to know how to get rid of them.Hi evilfantasy, sorry I did not follow your directions. After all, you're the PC doctor and now, hopefully, we can get my computer healthy and back to sanity again,

Anyway, here are a few things for you:

1. a MBAM Log (MBAM found 2 trojans)
3. new HJT log.
3. a AVG threat popup that appeared when MBAM scan completed. (I provided screenshot for you to look at and I clicked on 'move to vault' already)

All three are attached with this message.... so check the attachments included

[recovering disk space -- attachment deleted by admin]OK, we need to do another more thorough scan. This one won't take long.

Combofix log
combofix wouldn't run on my computer.

But anyway, I have reinstalled windows and all is okay now. Thanks for all the help earlier.Thanks for the update.
I was curious why combofix would not run. I had double clicked it like any normal proram and the loading bar appeared and it stopped there, nothing going on but I could use my computer as noirmal.

Anyhow, yeah no problem. thanks again evilfantasy for your help and I am happy that my computer is all good again
