That report looks fine.
So long as you got the from the MS site, that should be OK - you were probably connected to a contractor, who took the opportunityfor a sales pitch!
What you should do now is a little house-cleaning - just in case the rep was actually telling the truth!
Update your Anti-Virus, then download and install (UNtick 'Enable free trial of MBAM PRO' at the end of the installation) Malwarebytes Anti-malware (free version) www.malwarebytes.org
and update it, and run a full scan in your main account, and Quick scans in any other user accounts.
(this has the advantage of ensuring that every file gets looked at by both the AV and MBAM, for the price of a slightly longer scan time)
post the results of the MBAM scan, and we'll take a look.
