Hello

Before anything, let me say that this site is incredible, congratulations for doing such a good thing for the global community.

Now let me explain the problem with my computur, if anyone can help me I'd really appreciate that!

I have AVG installed, and two days ago, this software said that my computers had "Vundo" and "generic.downloader", so I ran a complete scan with AVG and after re-initiating the PC, still kept saying that. So I followed all of the 8-steeps that you recommend in this site.

Something I need to mention is that I run Malwarebytes' Anti-Malware twice, and both times it found threads, that's why I'm Uploading two files for this step (4).

Hope you can help me,

Kind regards

Uninstall your AVG Antivirus
Then run the removal tool
Here is the 32Bit version (most users): http://www.avg.com/filedir/util/avg_arm_sup_____.dir/avgremover.exe
Here is the 64Bit version: http://www.avg.com/filedir/util/avg_arv_sup_____.dir/avgremoverx64.exe

Run Startup Control Panel and remove any not required startups: (should be most!)

Install Avira free AntiVirus

Start up Malwarebytes again; Update it; then run a full scan (remove all found Malwares)

Now I know this is the third time, but running this with Avira protecting in the background may surprise you a bit ;)
Please let me know if Avira finds and removes any Virus on your computer (it would help my argument ;) )
 
Hey kimsland,

Thanks a l ot for your help, I,ve completed your steps and you were right, AVIRA deteted more trojans/bavkdoors, so I think this helps your argument :).

Malwarebytes found nothing, but while it was scanning, AVIRA detected some trojas. Later I ran AVIRA for a complet system scanning and it found somes. Attached are two files with the results.


Could you please explain me what hapends with AVG, why do you recomend completly uninstall it?

Againg, Thanks!
 
Hi caronte0330

Kimsland is away for a few days.

You did a great job.

OK we need to clean again with MBAM and SAS until the logs are clean. So I think once more each!

So UPDATE each and run, attach logs.

Mike
 
Hey here are the log files, this time all was ok, however I have notice a strange windows messeges yesterday and today, but I could not wrote it down. But next time it comes I'm gonna posted here.

If you have any other recomendation, please let me know.
 
Great Job!

See if you can catch the error and post it!

The SAS and MBAM logs are clean.

Looks like one more scan to do!

Download ComboFix

NOTE: If you have had ComboFix more than a few days old delete and re-download.

Get it here: https://www.techspot.com/downloads/5587-combofix.html
Or here: http://subs.geekstogo.com/ComboFix.exe

Double click combofix.exe follow the prompts.

When finished, it will open a log.
Attach the log and a new HJT log in your next reply.

Note: Do not click combofix's window while its running. That may cause it to stall.

Mike
 
I thought that would get it but a couple more things to do.

Run HJT select and remove the below
O2 - BHO: WormRadar.com IESiteBlocker.NavFilter - {3CA2F312-6F6E-4B53-A66E-4E65E497C8C0} - (no file)
O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)

Did you run the AVG removal tool advised by Kim? If not run it now, if you did then run it once more.

Copy all text in box by Left dragging Mouse then Paste to an open Command prompt!

Code: 
@echo off
cd\
attrib -h -s -r avg8*.* /s
del avg8*.* /s
rd "C:\Program Files\avg" /s /q
exit
exit

Then...

Download SD Fix to Desktop among other things Catchme to look for RootKits.

http://downloads.andymanchesta.com/RemovalTools/SDFix.exe

On Desktop run SDdFix It will run (install) then close.

Then reboot into Safe Mode

As the computer starts up, tap the F8 key several times.

On the Boot menu Choose Safe Mode.

Click thu all the prompts to get to desktop.

At Desktop
My Computer C: drive. Double-click to open.

Look for a folder called SD Fix. Double-click to enter SD Fix.

Double-click to RunThis.bat. Type Y to begin.

SD Fix does its job.

When prompted hit the enter key to restart the computer

Your computer will reboot.

On normal restart the Fixtool will run again and complete the removal process then say Finished,
Hit the Enter key to end the script and load your desktop icons.

Once the desktop is up, the SDFix report will open on screen and also be saved to the SDFix folder as Report.txt.
Attach the Report.txt file to your next post.

Mike
 
waooo I just really thought remove a trojan is an easy task! :)

Here is the SDfix's report. I'll wait for your comments.

Thanks for all the help!
 
Looks like we are finished but I do need a final HJT log!

What is the look and feel, status of your computer now.

waooo I just really thought remove a trojan is an easy task!
Click to expand...
Its like loosing weight! You cant lose in a minute what it took years to put on.

Malware is designed to be easy to get and hard to remove.

Mike
 
OK looks Good!

What about how computer is running?

Thread closing-------------------------------------------------------------------------------------------------------------

Start-Run
type
combofix/u
Enter or click OK!

Download OTCleanIt http://download.bleepingcomputer.com/oldtimer/OTCleanIt.exe

Save to desktop.

This will remove all the tools we used to clean your computer.
These tools update so often they require downloading again later if needed.

Double-click OTCleanIt.exe. Click CleanUp. Yes to the "Begin cleanup Process?"

Approve all if prompted by Firewall, Widows Defender or other guards or security programs about OTCleanIt attempting access to the Internet, allow all.

If prompted to Reboot click Yes.
OTCleanit will delete itself when finished, if not delete it by yourself.

-------------------------------------------------------------------------------------
Run CCleaner again twice or more on Cleanup temps, then on left click Registry then Scan for issues also repeat till clean.

D/L install and run ATF-Cleaner http://www.majorgeeks.com/ATF_Cleaner_d4949.html
clear all except passwords in all browsers you have. Run repeatedly until no more found.

Very good: KCleaner ftp://ftp2.kcsoftwares.com/kcsoftwa/files/kcleaner.exe
-------------------------------------------------------------------------------------
The issues can and are likely found is in System Restore so do the below

Start-Programs-Accessories-System Tools-Disk- System Restore and create a new Restore point. Name it "After cleanup at TechSpot".

Then Start-Programs-Accessories-System Tools-Disk Cleanup
Click OK to accept C:
Select all Boxes
Then click More Options
Here click System Restore and OK to "Are you sure" and the OK to Run.

As this runs it clears all but the most recent Restore Point but it does one other thing that can contain infested files and a huge amount of disk space.

It clears what is known as Shadow copies which are used by specialized back up programs.

This is if you have the Volume Shadow Copy running which is the default.
-------------------------------------------------------------------------------------

Every 2 weeks or so run mbam and sas until clean They take a while so leave scanning while you are sleeping working or watching TV. If not done under the gun they can be schedules not to interfere with computer time.

If they find something they can not clean then get back to us.

Additionally run CCleaner.

I have been using ThreatFire for more than a year, it just went from ver 3 to ver 4.

It was designed to co-exist with other Virus scanners.

Additionally it uses totally different process to protect. While conventional Virus scanners work from definitions ThreatFire works on recognizing Virus/Malware activity. It's like looking at it with 2 sets of eyes and from a different angle.

-------------------------------------------------------------------------------------
Look at http://www.javacoolsoftware.com/spywareblaster.html

Run SpyBot ocassionally and use the Immunize function.
http://www.safer-networking.org/en/download/

Install Hostman and allow it to disable DNS Client and select all 4 Host files and the Update
Hostman http://majorgeeks.com/HostsMan_d4592.html

A Disk scan and Defrag are in order.

Hello again mflynn,

Few things:

The last link does not work.

Which used softwares can I unistall and which can I disable to start automaticly once Widows start up? it seems like theris so much softwares...

What software can you suggest me to test my pc's perfomance? I've noticed that now it is using more memory, also the cpu usage is more.

Thanks
 
Ok I edited the link to a new location.

Get this to control startups http://www.mlin.net/StartupCPL.shtml

To see what is consuming the CPU cycles. Run Taskmgr click Processes then click the CPU tab.

This will put the high numbers at the top. The higher the System Idle process the better, but all other processes the lower the better.

Or Autostart and Process viewer is even better
http://www.konradp.com/products/autostart-and-process-viewer/download/apv_setup.exe

Run it approve all your current Startups then let it run in the System Tray for a couple hours then click Info and then full report click Copy to Clipboard and paste to Notepad (easier to read) the first ones are the Startups then the Processes by CPU usage you want to look at Recent CPU usage to find the hogs.

Doing the below will help free ram increase performance and speed up both Startup and shutdown.
Clean and tweak services

In services stop and disable all of the below just to get them out of the way for now for trouble shooting purposes.

Nothing is un-installed or deleted only disabled from running!

They can be put back anytime later but I would not, as none of them are needed by most home users and very few business users. Basically stuff M$ thought you should have.

Disabled uses no memory (RAM) and no CPU cycles.
Manual uses the RAM but a small amount of CPU.
Auto and not started they use even more RAM and CPU.
Auto and started even more RAM and CPU ..

Now in this case we disabling for trouble shooting purposes. But when we finish if you leave them all off until it is noticed that you need one (not likely for 99%) then it can be enabled.

Leaving these all off, then becomes a performance tweak/boost as they free some RAM and CPU cycles! Special note. If you are going to pick and choose then be aware that the small amount of RAM and CPU cycles of each one individually is not significant but as a group it is! So if you need most of them (or just think you do because you don't) then just as well enable them all)!

Distributed Link Tracking Client
Distributed Transaction Coordinator
DNS Client
Fast User switching
Health Key and Certificate Management Service
Indexing service
Messenger
Net logon
Net.TCP Port Sharing
NetMeeting Remote Desktop Sharing
IPsec services
QoS RSVP
Remote Registry
Uninterruptable power supply
Universal Plug and play
Web Client
Windows media player Network Sharing

IF you are using a wired network card and "NOT" using wireless on this computer then you can
also disable

Wireless Zero configuration

Wireless Zero configuration is only used on computers with a wireless NIC like a Laptop. Do not disable Wireless Zero configuration on a Laptop. Has nothing to do with other wireless hardware like wireless routers etc.

In short if this computer has a CAT 5 or 6 cable and no ability to connect wirelessly if that cable is unplugged, then you can disable Wireless Zero configuration.

This is not to be confused with Wired Auto Config do not disable that!

Lastly
Download AutoRuns http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
Run it let it scan, then when it says ready at bottom left corner click File at top and then Find.

Type in the find box file not found and hit enter and delete all lines that have file not found.

There are a bunch of old stuff that M$ thought you might or would need that no longer exist or for computers that are assumed to have SCSI or AMD processors but do not!

Then look carefully through all the other entries and delete anything that you may have had but uninstalled and thought was gone. If you are sure delete these also.

Then get RunScanner http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
Click Scan computer
Double click all Red lines to select, then click Item fixer and remove them. Then click Extra stuff again select all Red lines. Then click back to Malware hunting and Click the Item fixer again and remove these. Same as already said on AutoRuns stuf that was assumed to be need but you do not have.

None of these items can run as the file is missing so most of the improvement you may see comes as a quicker startup as windows no longer searches or tries to load some of these. But some have noticed a faster shutdown also.

Reboot and recheck with both AutoRuns and RunScanner.

Mike
 
wher I can do this part?

In services stop and disable all of the below just to get them out of the way for now for trouble shooting purposes.

Nothing is un-installed or deleted only disabled from running!

They can be put back anytime later but I would not, as none of them are needed by most home users and very few business users. Basically stuff M$ thought you should have.

Disabled uses no memory (RAM) and no CPU cycles.
Manual uses the RAM but a small amount of CPU.
Auto and not started they use even more RAM and CPU.
Auto and started even more RAM and CPU ..

I forgot the file, here it is.
 
Thanks Mike, I think my PC is now ready.
Just one thing left, I ran Registry Booster and tha sostware says there is 309 registry problems!! but unfortunately for resolving then, I need to buy the software.

What do you think about it?

Below is the log file of Registry Booster.
 
Well un-install Registry Booster (you don't need to pay for these things)
CCleaner has a Registry scan and repair button already (and it's free)
Not only that, but it's an excellent tool to remove all those temp files
 
10-4 I agree get rid of Registry Booster.

CCleaner has one of safest gentlest Registry cleans of all.

Your startups look OK I see no hogs but you can use Startupctl to remove the Adobe junk, totally useless and does not effect the usability of Adobe.

You did a great job.

I am glad to see you have ThreatFire some are intimidated by the learning if the approval process.

Once you are comfortable with it and have approved all that you know to be good then open TF and click settings then slide the slider (looks like a cell phone signal strength) all the way to max.

This will take it from conservative to paranoid and it will be inquisitive again for a couple of days. But in a day or so it will settle down again.

Note I am often asked why TF sometimes queries things like FF or IE etc when they have already been approved. Usually it is an update that has changed something.

Also remember if you are unsure of an item, if you quarantine it then you have the option of approving it or deleting it later if needed.

I did not see HostMan in the startups highly recommended!

Mike
 
Hello again, I did what you suggested me about the TF configuration, but I got a problem now. TF report me that one application (firefox.exe) was accesing internet in a very strange way, so I choosed to kill the process (I think that was a mistake) and now when I try to star Firefox I get this mesassge:

"Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system"

What do you think I can do to resolve this?

I almost forgot, where can I get HostMan?
 
Hostman see bottom of post #12!

For FF first go into TF Threat Control and look at Denied and if FF is there just check it and then remove to free it. Then check Quarintine and check and restore FF if there!

Then run Taskmgr and end FF or reboot!

If TF intervenes again approve FF. By maxing that slider we have made TF paranoid.

Mike
 
Great!

Some programs will clear some of the blocked items when they put their own blocklist in like SpyBot and SpywareBlaster both good programs.

So after running these or others that may do that, just update HostMan and merge (not overwrite) and then check and remove duplicates.
