i have a self build pc....very nice too
i am very pc literate, yet in spite of my best efforts, i recently had to do a reformat due to a virus called 'seneka'
i dont visit porn sites or moody gambling sites, i don't randomly browse sites, so where it came fom is a mystery to me.
i spent a day and a half going round in circles before calling it a day and resorting to the reformat...
...but on a lighter note, my pc now has the 64 bit o/s it was crying out for from day 1
