Can you please help me with my computer?

[Marshall]

Hey guys!
I am generally tech savvy, but I think my computer may have gotten some sort of virus relating to Google.

I noticed a problem a week or two ago that whenever I clicked on a link on Google it would take me to some random page, but after the first try on the link it ususually went back to working.

But recently I had this thing where my computer shut down a few times without me telling it to and now when I go into Google the results that pop up are not evenrelevantt like "facebook" brings up like blog websites about facebook but not the website itself, or "twitter" brings up random PARTS of twitter but not the main page like it always used to.

And if I CLICK on the links they now ALWAYS take me to some randomized page about anything from legal issues to products for sale.

Please help,

Marshall
