My computer has started running really slowly. I have checked that my modem is good and have upgraded my wireless router.

I think I may have a virus or malware.

I have attached a hijakthis log file.

 

Thanks for any help that you can give me.

Robert

  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • The scan may take some time to finish,so please be patient.
  • If potential threats are detected, ensure that Quarantine is selected as the Action for all the listed items, and click the Apply Actions button.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.
POST THE LOG FOR MY REVIEW.

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 immediately.

Here are the requested logs.

I could not find the HiJackThis file in my computer, but I saved it to my desktop, so I deleted it from there.

When I went to run the AdwCleaner, it said that I did not have the latest version.

I went to the download site (Toolslib) and when I downloaded the latest version it said that Windows defender had protected my computer.

I said to run anyway, and a pop up said that the file was corrupted and would not run.

 

Also, the ToolsLib webpage showed the message below;

 

You are browsing ToolsLib in unencrypted mode. For security reasons, please consider using the encrypted (HTTPS) mode as soon as possible.

Things are running slightly faster, but certainly not like when I first got this computer (Nov 2015).

Have you seen anything in any logfiles or text files that would point to an infection or malware?

There could be some remnant items.

Run an online scan with Eset (easiest with Internet Explorer): http://www.eset.com/onlinescan/
To shorten the scanning time disable your antivirus program while scanning.

Select Enable detection of potentially unwanted applications.
Click Advanced Settings.

Select:
Scan Archives
Scan for potentially unsafe applications
Enable Anti-Stealth Technology


Click Start.

When the scan is finished, click on List of found threats and then Export to text file. Copy the content of the text file and paste its content in your reply.

This may take awhile, run it when you know you will not need the computer for an hour or two.

Websites would load much faster. Sometimes it takes 20 to 30 seconds to load a webpage. It used to be much faster than that.

Thanks for your help.
