Computer started running slow 3 days ago and almost unusable on Friday. Noticed that both CPU usage and physical memory were at almost 100% most of the time.

Spent today running AVG antivirus and Malware bytes - thought everything was cleaned up. Restarted a few times.

CPU usage and physical memory high again and I cannot get into any files at all. All are being used by another user. (includes any files needing a password)

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
    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.




Download
Malwarebytes Anti-Rootkit to your desktop.
  • Double-click the icon to start the tool.
  • It will ask you where to extract it, then it will start.
  • Warning! Malwarebytes Anti-Rootkit needs to be run from an account with administrator rights.
  • Click in the introduction screen "next" to continue.
  • Click in the following screen "Update" to obtain the latest malware definitions.
  • Once the update is complete select "Next" and click "Scan".
  • When the scan is finished and no malware has been found select "Exit".
  • If malware was detected, make sure to check all the items and click "Cleanup". Reboot your computer.
  • Open the MBAR folder and paste the content of the following files in your next reply:
    • "mbar-log-{date} (xx-xx-xx).txt"
    • "system-log.txt"




Scan with Farbar Recovery Scan Tool

Please re-run Farbar Recovery Scan Tool to give me a fresh look at your system.

Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.

Running it on another one may cause damage and render the system unstable.

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on
    icon and select
    Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

just to clarify - I saved fixlist.txt to the desktop but FRST is in its own folder on c:
How should I proceed?

You need to have FRST and fixlist.txt in the same place, no matter where.

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 :)


Recommended reading:
MUST READ - security tips:

MUST READ - general maintenance:


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:
TFC - to clean unneeded temporary files.
Malwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
McShield - to prevent infections spread by removable media.
Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
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
    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.
