i dont know who that person is but i can tell you how to get rid of anything that they put on your computer and if needed i can log in remotely to work with you on getting the form filled out
to get rid of any virus or malware
download this program called malware bytes
use the square blue box that says download from bleeping computer
it should be 1 file named mbam-setup.exe
for the form i would suggest downloading it and saving it and then opening the copy on your computer and filling it out.
if you want to send me the link i will look at it but many government websites want the form mailed in and its not set up to fill out online. they expect you to print it and then fill it out by hand and mail it in. Old technology but governments are not known for being high tech.
