A couple of days ago, I had an incident where my computer got hijacked by malware which kept redirecting my searches. I used malwarebytes to remove the malware which seemed to get rid of the browser hijacker, but since then if the computer is on, I have trouble with my internet connection. When I put the computer in sleep mode, or turn it off, my other devices connect to the net just fine, but not if the computer is on the network.

I'm running Windows 10 on a Dell inspiron 17 5000 series.

 

I would really appreciate any help with this issue.

 

Thanks in advance.

Hello and :welcome:

 

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button. button.

FRST.gif Fix with Farbar Recovery Scan Tool

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


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

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 FRST.gif icon and select RunAsAdmin.jpg 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 finishes FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

Hi,

 

I applied the fix, but still seem to have issues when the laptop is on the network. I even put inn a support ticket with my ISP about the issue in case there was a separate issue going on at their end. They did identify a problem with the router and reset it. However the problem is stl there whenever I put the laptop onto the network.

I've tried three times now to attach the fixlog. txt file, but although I eventually got it to upload, now it won't attach to my reply.

The internet is wireless broadband. Other devices work on the internet as long as the laptop that had the virus is not connected. I've run scans with Windows defender, again with malware bytes, rogue killer and tdss killer all scans are clear. I'm opening a ticket with my ISP as I have a feeling that this is an issue with the included VOIP service.

Since there are no more problems, we can declare this PC clean thumbs_up_smiley.gif

Now, we can proceed with post-cleanup procedures. Let's remove my tools and create a new, non infected restore point concurrently deleting old ones.


Step 1. - Creation of system restore point and tools removal.


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). I don't need it for review.


Tool deletes old system restore points and creates a fresh system restore point after cleaning.


Step 2. - Tips and tricks to keep your computer clean, safe and in a good shape.


Security tips - highly recommended reading:


Maintenance tips:


Additional software that I personally use and install on all my clients devices:

  • Malwarebytes' Anti-Malware(paid version highly recommended) - 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.
  • uBlock - to surf the web without annoying ads!
  • Qualys BrowserCheck - cloud service that scans your browsers and plugins to see if they’re all up-to-date.

My help is free for everybody.
