That is good news on your first issue. It may be that some of the superfluous stuff all manufactures seem to think we all 'want' on our new machines are being interpreted as 'spy' by Spyhunter. Beware over-frenetic programmes that 'find' all sorts of stuff - and then sometimes ask you to part with 'folding drinking vouchers' to 'get rid of them'.
My new HP laptop earlier this year had all sorts of HP crap on it that I just did not want. I'm sure you know to be 'careful' when installing anything to check any 'optional extras' - I always choose 'custom install' and deselect the garbage. Even Adobe are 'automatically' installing 'extra' stuff if you don't watch out.
Again, I think you would find Malwarebytes (free) a very useful tool to have. Lastly, be careful not to have two 'major/always on' anti-virus progs running together - it always used to be said that this can cause conflict.
