I am the resident computer guy. So I get lots of requests to fix computers. It is now so easy to remove most malware that I am really surprised people still ask me. Here is how I remove malware on most systems.
Step 1. Download the Trial Version of malwarebytes
You can get the trial version for 30-days. It is great software so I encourage you to buy it – https://www.malwarebytes.com/ Download the free trial on your desktop or somewhere you can easily find it.
Step 2. Restart your system in “Safe Mode”
Once malwarebytes is downloaded on your system, restart the computer and hit the “F8” key to over and over until you are given the option to boot the system in a different state. Select “Safe Mode”
Step 3. Install Malwarebytes
Double click Malwarebytes, and follow the instructions.
Step 4. Start Malwarebytes
How long this takes depends on how much data Malwarebytes has to go through and how fast you system is. Some things will take more than normal antimalware software. Rootkits for example, are a little harder to get rid of. For these, I have found it helpful to google the errors, warning banners and symptoms you are seeing to find someone else who had the same issue and fixed it. Some are so bad you will have to search for an answer on a separate system.
Good luck to you.
