How do I uninstall and reinstall safari 5.1.2? 2011 MacBook Pro OS X 10.7.2

I seem to have been hijacked by ad tracker crap. Safari is acting quite strange; i.e., there seems to be a lot of certificate rejections and very often a particular bookmark will show up as "access denied". On occasion when opened, it will go somewhere completely off the wall. Many times "facebook.com" shows up in the address, but that's not where it has gone. I realize I'm doing a pretty bad job of describing all this, but I'm at my wit's end... My theory is that removing it all together and then reinstalling a fresh copy might solve these hijackings. Thanks, mkcos

MacBook Pro, Mac OS X (10.7.2)

Select Apple menu > System Preferences > Network > Advanced > DNS. Under “DNS Servers” you should have one or more numerical addresses, such as “192.168.1.1” or “10.0.0.1”. What are those addresses?

I left out a .1 on the first address. The correct number is: 192.168.1.1 I assume this is the router id... But, this is just one of the many things I know nothing about...

That should be your router. What are its DNS settings?

Yes, apparently it's the second and third one's that may be the problem. I found a reference to those particular addresses, but didn't really find an explanation for them other than their being bad. Should/could I just delete them? They come up as being assigned to earthlink.net (which I do use), but they don't seem to want to take ownership...

Your preferred DNS server is your router, acting as a proxy for a remote server, which you haven't yet identified. All requests will go through it, unless it's not working. The others are, as you say, your ISP's DNS servers.

Well, then this is not the avenue to pursue? While those two were associated with earthlink, they were nonetheless regarded with suspicion as having something to do with ad tracker stuff. Unfortunately, all the refernces I found seemed to require more technical knowledge than my feeble mind can assimilate. What would happen if I did delete them, assuming that's even possible? At this point then, can I assume that the problem I'm having is not coming from Safari itself at all? Sorry to keep throwing the questions. Kevin

If you won't tell me what DNS servers your router is using, I have nothing else to suggest.

That depends on what kind of router you have. If it's not an Apple device, it probably has a web interface that you can access here:

http://192.168.1.1/

You'll have to navigate your way through that interface, or consult the manufacturer.

It's a Linksys, pretty new... Here is the only other number I could find that seemed related: 192.168.1.103. Alternately, I do have a brand new AirPort Extreme... Would it be worth connecting it, pulling the Linksys and seeing if the problems go away? I'm really at a loss to solve this stuff and it's just ruining my "internet experience".

If you don't know how the Linksys works and don't want to learn, then yes, I'd recommend you use something else. Set up the AEBS to get an address from DHCP and use the default DNS settings from DHCP. The Apple documentation is here:

Hey had the same problem, EASY FIX!, check you time and Date preferences, I had set my date back recently and that messed with the security certificates. Make sure your date and time is good, and it should fix itself
