email behave strange

Repa,
I was just trying to email my 3 Reps. in Congress, when I clicked on a website, that a yahoo search had pulled up. I first checked the site with siteadvisor, & I got the green light. I enabled auto scroll and the page started scrolling on it's own, and the whole page acted strange. Since I got the ok from siteadvisor, I temporarily allowed, since sometimes I've noticed that it is required. I finally left the page and when i got back to my emails I was writing the mouse cursor was running around, and moving on it's own, etc. It finally got to working like it is supposed to, and I got my emails finished and sent.

Here is the site I went to stevenmcollins.com/WordPress/?p=5095.

1) Do you think I picked up something from the above site?

2) Do I need to do anything besides my daily scans that you suggested?

3) I tell you, I just can't win on this stupid computer!

Can't find anything wrong with the site, but no user comments on it, so you have to take Site Adv isor's rating with a grain of salt. You could run ccleaner and Malwarebytes quick scan as a precaution, but I doubt anything is wrong.
