Computer won't allow windows update or download of Malwarebytes

24 posts in this topic

My computer is acting very strangely. It won't allow for windows update and is giving me a security certificate warning when I try to open hotmail and when I tried to download Malwarebytes. I had a virus a while back and someone here helped me and said all was well, but the computer has been slowing down more and more and now this. Please help.

Hello tigweld! Welcome to Malwarebytes' Anti-Malware Forums!

My name is Borislav and I will be glad to help you solve your problems with malware. Before we begin, please note the following:

  • The process of cleaning your system may take some time, so please be patient.
  • Follow my instructions step by step if there is a problem somewhere, stop and tell me.
  • Stay with the topic until I tell you that your system is clean. Missing symptoms does not mean that everything is okay.
  • Instructions that I give are for your system only!
  • If you don't know or can't understand something please ask.
  • Do not install or uninstall any software or hardware, while work on.
  • Keep me informed about any changes.

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:
    1. DDS.txt
    2. Attach.txt

    [*]Save both reports to your desktop. Post them back to your topic.

Hi,

Thank you for your help. The time on the computer somehow changed and was the cause of the problems with windows update and possibly the hotmail issue as well. The computer still runs slower than normal though.

The time on the computer somehow changed and was the cause of the problems with windows update and possibly the hotmail issue as well.

So these problems are fixed, right?

Now:

  • Launch Malwarebytes' Anti-Malware
  • Go to "Update" tab and select "Check for Updates". If an update is found, it will download and install the latest version.
  • Go to "Scanner" tab and select "Perform Quick Scan", then click Scan.
  • The scan may take some time to finish,so please be patient.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Make sure that everything is checked, and click Remove Selected.
  • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
  • Copy&Paste the entire report in your next reply.

Extra Note:

If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediatly.

In your next reply, please include these log(s):

  1. Malwarebytes' Anti-Malware log
  2. a new fresh DDS log only

**Note: If you need more detailed information, please visit the web page of ComboFix in BleepingComputer. **

Please note that these fixes are not instantaneous. Most infections require more than one round to properly eradicate.

Stay with me until given the 'all clear' even if symptoms diminish. Lack of symptoms does not always mean the job is complete.

Kindly follow my instructions and please do no fixing on your own or running of scanners unless requested by me or another helper.

Please download ComboFix from

Here or Here to your Desktop.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved and renamed following this process directly to your desktop**

  1. If you are using Firefox, make sure that your download settings are as follows:
    • Open Tools -> Options -> Main tab
    • Set to Always ask me where to Save the files.

[*]During the download, rename Combofix to Combo-Fix as follows:

CF_download_FF.gif

CF_download_rename.gif

[*]It is important you rename Combofix during the download, but not after.

[*]Please do not rename Combofix to other names, but only to the one indicated.

[*]Close any open browsers.

[*]Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

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

  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause unpredictable results.
  • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.

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


  • Close any open browsers.
  • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
  • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
  • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.

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

[*]Double click on combo-Fix.exe & follow the prompts.

[*]When finished, it will produce a report for you.

[*]Please post the C:\Combo-Fix.txt for further review.

**Note: Do not mouseclick combo-fix's window while it's running. That may cause it to stall**

If I log out of my hotmail account and try to log back in it says wrong password. I have to retype the log in name and password, then it works. It's as if the login is remembering the wrong password.

I installed Firefox and it won't remember my hotmail password no matter what I try.

After I copy and pasted the uninstall command, it says windows cannot find ComboFix... I did not previously uninstall it, so I don't know why it can't find it.

It says no items match your search. I wonder if it has something to do with the date being wrong on my computer when I began doing all this.

No, no problem for your data. How exactly is the name of ComboFix?

On the desktop it says Combo-Fix

Should I try the command in the command prompt window?

Ok, I dragged it into the recycle bin. Do I need to worry about the steps that the uninstall was suppose to take care of such as the clock reset, restore point, etc?

I followed the other 3 steps you outlined. So, I guess I'm good to go? Thank you for your help!
