need a computer genious's help!

[t-maxxracer32]

hey guys our family computer has been taking a dump for a while and its finally to the point to where nobody wants to use it... cept me

here is the problem

if i click on internet explorer it will take FOREVERRRRRRRRR to load up. like litterally 20-30 minutes. if i click on a link... it will take about 5-10 minutes for it to load. im on ebay trying to list some stuff and when i try and upload some pics.. since it has to bring up that new link it takes FOREVER.

now. once it is on the internet it is perfectly fine. lags a little but its bearable. luckily i found a backroute for us so it is not too bad (go to my computer and in the adress bar act like its the internet and it will work fine from there)

so do i have a virus... or is something set wrong... or what the heck do i do!

im not much of a wiz when it comes to stuff like this but if you tell me what to do to possibly fix it i can/maybe do it.

thanks for any help!
