where's my flashplayer gone & why ca't i download another 1.

hi ive tried almost everything to download flashplayer again . my pc is only a year old.i have had a few viruses but got rid of with avg free,
i also have avasti on here and thats been useful too.
i used to use alot of flash sites like cocacola.com.au for competitions but now flash wont work.
i tried what you advised in a previous thread but still no download all i get is a blank space with the little thing in corner but no movie.

also if i try to download absolutely anything a thing pops up saying.

" internet explorer cant download this as the website cant be found or is not available"

please help im going crazy lol.

thanks in advance.

Try the uninstaller first as seen here:

Fix for flash player (viewing video)

As to the overall issues:

Is this a new problem? Were things working OK previously? Any new hardware or software?

If this is a new problem try a System Restore to a point prior to the problem:

start > All Programs > Accessories > System Tools > System Restore

ok ill try the link.
yes it happened about 3 months ago new hardware was a webcam.
few new software apps but nothing id consider major.
only the virus but i thought that was gone.

i notice in system thingy there are a few dll's say changed instead of ok.

ill get back to u after i check other 2 things u said thanksssss

Try downloading from www.filehippo.com, I had a similar problem on the official website but it worked from this one.
Also contains loads of other useful downloads.

thanks heaps i cant download anything on IE but can with firefox browser.

I would suggest upgrading to IE 7 if you can:

Or go to start > All Programs > Windows Update

Download all critical updates if you haven't.
