ONI will be shaking his head at me ......

I remembered I had an old flicker account ....so went into it to try and upload my pics
everytime I press upload , I then get into my documents ...I can click on a pic , but then when I press review to check it is the right pic I get a message to say it has crashed.
every time
on the side there is a free download to make it easier and I maybe thought it was an update seen as I hadn't been on the site for a couple of years..
so I clicked on to download it ..its a flash adobe thing
well as soon as I get going I get this warning saying do I want to continue because of potential threats and my anti virus will be closed off for a minute ..and this can happen and that can happen ..
so now I daren't do it ....
can one of you put my mind at rest please

also
everything on my screen is getting blurred ..like a black trail next to it ..
what does this mean please ?
thankyou for anything you can give me
