Is a Mac safe from government Peeking or this?

Yours is a 2 part Q:
1) Privacy
2) Security
Both are hard to attain and equally hard to maintain.
1) Since all devices that interconnect using the Internet use the same 'mechanisms' (TCP/IP); and browsers come with liberal settings (to give users "that rich Internet experience"), it's been determined by very smart people other than yourself what you should be seeing and doing over those mechanisms; and they have figured out ways to monitor where you go and what you do when you get there, plus influence your future behavior.
Unless you modify your browser(s) automatic behavior, they will always have this influence over you.**

2) Your computer symptoms indicate an infection by one of the 'rogue' malware items that plague Windows users, but Apple has been lately getting the same garbage.
Giving us a name of the malware that's shut you out would allow more specific removal instructions.

I use Linux and never get this crap, but I've seen thousands of PC users here on Yahoo in the same boat as you.

** Does the Government monitor what everyone is doing?

"A former NSA official...William Binney...[accused] NSA Director...Alexander [of] playing a “word game” and that the NSA was...collecting e-mails, Twitter writings, internet searches and other data...and indexing [them].
He said the NSA began building its data collection system...prior to 9/11, and then used the terrorist attacks...as the excuse to launch the data collection project. ... Binney was contradicting statements made...by Alexander, who told the crowd...that his agency “absolutely” does not maintain files on Americans.
But ACLU staff attorney Alex Abdo...noted that a gaping loophole in the law...allows the agency to do dragnet surveillance...and hold onto that data.
