Hello,



They call me TwinHeadedEagle around here, and I'll be working with you.



Before we start please read and note the following:
  • At the top of your post, please click on the "Watch thread" button and make sure to check Watch this thread...and receive email notifications. This will send an email to you as soon as I reply to your topic, allowing me to solve your problem faster.
  • Please do not install any new software during the cleaning process other than the tools I provide for you. This can hinder the cleaning process. Please do not perform System Restore or any other restore.
  • Instructions I give to you are very simple and made for complete beginner to follow. That's why you need to read through my instructions carefully and completely before executing them.
  • Please do not run any tools other than the ones I ask you to, when I ask you to. Some of these tools can be very dangerous if used improperly. Also, if you use a tool that I have not requested you use, it can cause false positives, thereby delaying the complete cleaning of your machine.
  • All tools we use here are completely clean and do not contain any malware. If your antivirus detects them as malicious, please disable your antivirus and then continue.
  • If during the process you run across anything that is not in my instructions, please stop and ask. If any tool is running too much time (few hours), please stop and inform me.
  • I visit forum several times at day, making sure to respond to everyone's topic as fast as possible. But bear in mind that I have private life like everyone and I cannot be here 24/7. So please be patient with me. Also, some infections require less, and some more time to be removed completely, so bear this in mind and be patient.
  • Please stay with me until the end of all steps and procedures and I declare your system clean. Just because there is a lack of symptoms does not indicate a clean machine. If you solved your problem yourself, set aside two minutes to let me know.
  • Please attach all report using
    fjqb1h.png
    button below. Doing this, you make it easier for me to analyze and fix your problem.

  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

Sorry for the delay, yesterday I noticed the watch thread was active and didn't realize that the email option was not active.

I have run both of the programs and attached the requested files.

After running both of those programs, the automatic reboot seems to have activated the attack on my pc again. Norton has blocked 2 intrusions in the last 15 minutes and my IE history is now showing over 100 websites visit in the last 2 hours.

After it rebooted, I received a high usage performance warning for SVCHOST.exe

I opened task manager and found one instance of svchost.exe using over 600mb of memory and also the same java.exe *32 was up and running again (currently taking about 250mb of memory).

Many, many thank you! I will continue to monitor over the next couple of days for any signs of infection. Do you suggest that I begin removing these additional programs or should I just relocate them to a "Toolkit" folder?

Just waking up and checking the pc this morning. There is not any bogus / extra websites showing up in my IE history. The only negative thing to note is I have received a memory low message a few different times since we began this battle yesterday. I did remove the Avanquest Fit-It Utilities program from my pc yesterday (after we completed our previous step)since it was a borrowed program and didn't seem to be helping anything in this process.

Also, I uninstalled Spybot Search & Destroy 2.4 during our steps yesterday due to program conflict (couldn't find where to disable).

I uploaded screen shots of my current task manager list. Do you see any programs that may be running in excess or not necessary to run (ex. java.exe *32) ? When I compared the task manager to another pc, I did not see java running and wondered if this one was an anomaly or is something residual running.

Java process is probably update or browser component. Uncheck Show processes from all users.


Glad I could help. We will delete all used tools and I'll give you some tips to harden your security and learn how to protect yourself :)

The Importance of Software Updating:

In order to stay protected it is
very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.

Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.




Recommended additional software:
icon_arrow.gif
TFC - to clean unneeded temporary files.
icon_arrow.gif
Malwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gif
Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gif
McShield - to prevent infections spread by removable media.
icon_arrow.gif
Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gif
FiheHippo.com Update Checker - to keep your programs up-to-date.
icon_arrow.gif
Adblock - to surf the web without annoying ads!



Post-cleanup procedures:


Download DelFix by Xplode and save it to your desktop.
  • Run the tool by right click on the
    51a5ce45263de-delfix.png
    icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run and wait until the tool completes his work.
  • All tools we used should be gone. Tool will create an report for you (C:\DelFix.txt)
The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.

Any ideas why I started getting these memory low errors? Are they related to these programs we used for clean up and removing them will fix it?

When I get it again, I will get a screenshot. In an earlier post I did include a shot one of the memory low messages. Some of the messages give a prompt to let Windows close select programs (ex. Outlook, IE, Dropbox, etc.) and others do not prompt any programs at all, just a message stating the memory is low. I have already seen at least one instance since Delfix was run.
