imac very slow but disc ok
My +/- 5 year old iMac is running very slow - all applications - Safari, Photos - in fact any function.
I am running Snow Leopard.
I repaired the disc with the Snow Leopard disc utilities and it is ok.
I am wondering whether it has a virus. I tried downloading a virus scanner but the process takes so long (and the program I eventually downloaded would not work with Snow Leopard in the end).
Any suggestions before I take it in to the Geek Squad?
Thanks
iMac (24-inch Early 2008), Mac OS X (10.6)
