I am going to post instructions to run security scans to look for adware. These scans can not be run in the Windows forums, so I will request that this topic be moved to the Am I Infected, What Do I Do? forum.
Before I post the instructions I would like to make you aware of the most common way to windup with PUPs being installed on your computer.
Bundling third party software in free or paid software downloads has become a common practice. Authors of the primary programs offered to be downloaded make extra revenue by allowing third party programs to be bundled in their product downloads. There is a surprisingly large number of people who are not aware of this and will simply choose the Express installation option which will automatically install the author's software and all of the bundled third party software as well. These PUPs (Potentially Unwanted Programs) may include unwanted toolbars, software which can change your homepage, or change your default search engine, and Adware.
This can be avoided quite easily by using the Custom installation option. This will take a little more time because you will need to read through the download information to see what the third party software is so that you can choose whether you want it or not. A lot of these will have a box to select the software which will usually already have a check in the box. These are easy to spot. There is another way that these a presented, this is a written description of the software which initially looks like it is describing the author's software. These usually will have the option to decline the installation.
Please run the scans suggested below in the order that they are requested, this is a must for RKill. Post the logs generated by these scans in your topic in the order they were run. Please do not wrap your logs in quotes or code brackets or use use spoilers.
Please download AdwCleaner and install it.
When AdwCleaner opens click on Scan to start the scan.
Once the search is complete a list of the pending items will be displayed. If you see any which you do not want removed, remove the check mark next to it.
If there are no malicious programs are found you will receive a message informing you of this.
Click on Clean to remove the selected items. If you have any questions about any items in the list please copy and paste the list in your topic so we can review it.
You will receive a message telling you that all programs will be closed so that the infections can be removed. Click on OK. The computer will be restarted to complete the cleaning process.
When the cleaning process is complete a log of what was removed will be presented. Please copy and the paste this log in your topic.
Please run Malwarebytes AntiMalware
Please download Malwarebytes Anti-Malware 3.3.
1) Double-click on mbam-setup.exe, then click on Run to install the application, follow the prompts through the installation.
