DO NOT PAY ANY COMPANY to remove virus remotely. Most are scams.
First, download MALWAREBYTES
https://www.malwarebytes.com/mwb-download/
Next, download CCleaner
https://www.ccleaner.com/ccleaner/download/standard
Next, download Glary Utilities
https://www.glarysoft.com/downloads/
After they have been installed and updated, disconnect the computer from the Internet. (disable the network devices)
If possible, backup all your documents to another location (like an external drive or even DVD's)
Next, run malwarebytes. Depending on the results (ie, something found) you may have to run CCleaner.
If nothing is found, most of the time everything is OK.
Reboot the computer
Enable the network devices.
Next, create a System Restore Point. (Some virus will turn this off, this step insures that the program is running)
I would also recommend that you check your Firewall settings. If you are running Windows 10, Windows Security is sufficient for home use. Make sure is up-to-date You do not need to buy a separate Antivirus software. AND you should never run more than one Antivirus program at the same time, They conflict with each other and cause gaps on their definitions list
Next, run Glary Utilities. "One-Click Maintenance" "Scan for Issues"
After 28 days, run Malwarebytes again. If everything is OK, remove the program.
Run Glary Utilities at least once a month.
I hope these help. Good luck
