Malware - ad bar embedded on IE9!

I was trying to install PDF splitter tool and realized later that some malware was brought in with it. When I launch IE9(Win 7), and typed in google.com, at the bottom of the page I was shocked to see the malware embedded! Image attached. How can this happen? A security glitch?

Google Dictionary - pronunciation tool defect

Win 7, IE 9

Go here - http://www.thefreedictionary.com/reticence click the speaker icon as many times - there is pronunciation.
Now go here - http://www.google.com and in the search bar/field enter the "define: career"
click the speaker icon, works only once.

It does not work/repeat pronunciation on refresh or resubmit. To me its a defect, for Google, may be not?

LinkedIn authentication error

The LinkedIn authentication issue has been teasing me for a while now (may be a year or longer), where I supply the password, it rejects the first time and accepts it at the second attempt!

No fat fingering...just the very same entry twice.

Today, minutes earlier, I logged in with the same password from para 1 (above) which worked this time and searched for someone, viewed that profile, on clicking 'Connect' I was prompted a login screen on top of the ribbon! WHYYYY? - so

Bug #1. Now, when I enter the password, login fails, the same working password from first para 1. Safely I clicked 'Home' on the LinkedIn home page (the session and login was still active and the top frame/header/ribbon appeared on the background) and navigated away and played around! -

So Bug #2 or 3 (if I include the first one as 1...it wasn't a repro as regularly I liked). OS: Win 7 IE: 9 LINKEDIN - you can take this bug for free....
