Hello, recently my computer has experienced incredibly reduced download speeds, to the point where it reached a low of about 300 bytes. My average download speed is between 2-3 megabytes. Also, when attempting to download anything from Google, upon opening the file i get an error message stating the file is corrupt, or the file simply doesn't download at all. I've ran multiple PC scans and cleanings to no avail. Attached is a log after I scanned my PC with Hijack-this, a program i have never used before which warned me to seek professional help before fixing any files, which brought me here. Any help or advice would be greatly appreciated, and thank you in advance for your time. :)

  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.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.
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.

Download the correct version of this tool for your operating system.
Farbar Recovery Scan Tool (64 bit)

and save it to a folder on your computer's Desktop.
Double-click to run it. When the tool opens click Yes to disclaimer.
Press Scan button.
It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
