Hello. i had manyyyy viruses & untwanted programy on my computer. in fact, i did a virus scan and they found 306 {trojans, email worms, you name it.}. anyway, i decided to just erase the whole hard disk and re-install the OS [operating system]. I've already completely wiped the whole har drive.....
