I run AVG antivirus on my Windows 7 Dell computer. I have recently been infected with these Trojans. AVG blocks the threats but I get this message

 

Cannot be removed. Access is denied.

 

I have tried to download an updated version of AVG - and get the message that the download is infected with a virus and has been aborted. I get the same message when I try to download other antivirus programs as well. I also got the same message when I tried to follow the instructions on this site for dealing with this problem...

I live in a rural area with and don't have easy access to a computer technician who could take care of this.

Can you help, please?

 

Thank you.

Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

 

 

 

Scan with DDS

Download DDS and save it to your desktop from here or here or
here.

Disable any script blocker, and then double click dds.scr to run the tool.

When done, DDS will open two (2) logs

DDS.txt: save to your desktop then post its contents in your topic
Attach.txt: save to your desktop then attach it to your next reply

 

 

 

Scan with Malwarebytes Anti-Rootkit

Please download Malwarebytes Anti-Rootkit from here Malwarebytes : Malwarebytes Anti-Rootkit and save it to your desktop.

Be sure to print out and follow the instructions provided on that same page.

Caution: This is a beta version so please be sure to read the disclaimer and back up any important data before using.

  • Double click the mbar.zip file to open it, then 'Extract all files'.
  • Double click the mbar folder to open it, then double click mbar.exe to start the tool.

Check for Updates, then Scan your system for malware

If malware is found, do NOT press the Cleanup button yet. Click EXIT.

I'd like to see the log first so I can see what it sees. You'll find the log in that mbar folder as MBAR-log-[date and time]***.txt . Please attach that to your next reply.

Good evening Marius,

 

 

I am unable to download DDS from any of the links above. When I try to download the file, I receive a message that says the file contains a virus and the download was deleted.

Reboot into safe mode with networking, then try the following:

 

 

Scan with FRST in normal mode

Please download Farbar's Recovery Scan Tool to your desktop: FRST 32bit or FRST 64bit (If not sure: Start --> Computer (right click) --> properties)

  • Run FRST.
  • Don´t change one of the checkboxes and hit Scan.
  • Logfiles are created on your desktop.
  • Poste the FRST.txt and (after the first scan only!) the Addition.txt.

Thank you Marius. I am going to be away from my computer for 3 days. I will attempt the procedure when I return Monday evening. Can you please confirm what you mean by "safe mode with networking". I know how to open the computer in safe mode, however this is a stand alone machine with no networking at all.

OK, just to clarify: The comnputer we are working on is stand alone?

How do you download files then?

 

Do you have another computer and this one is displaying the virus message on downloaded files?

Hello Marius,

 

Yes, I'm working on my home computer with an internet connection and I download the files directly to my computer.

 

At my office I am connected to a network with a  file server so when I see the term 'network' I thought that was what you were referring to.

 

Just to be clear - I am working with a single computer at home and when I try to download the files you have asked to download - I am not able to do this on my computer.

 

Thank you again for trying to help me with this problem.

Do you have another computer nearby where you can download?

Try to do something else...

 

 

Scan with FRST in normal mode

Please download Farbar's Recovery Scan Tool to your desktop: FRST 32bit or FRST 64bit (If not sure: Start --> Computer (right click) --> properties)

 

Save the file as FRST.COM or FRST64.COM to your desktop. Perhaps you have to change IE´s download behaviour to have the possibility to change the file name before the download starts.

  • Run FRST.
  • Don´t change one of the checkboxes and hit Scan.
  • Logfiles are created on your desktop.
  • Poste the FRST.txt and (after the first scan only!) the Addition.txt.

Hi Marius, I'm afraid that I cannot download anything to this computer. I get the same message. Thank you for your assistance. I think it is probably time for me to take the machine into the city to a computer technician.

I appreciate all the time you have spent trying to help.

It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
