do computer get man flu

so i have been working hard to add my redbubble designs to leggings 

so as a bit of a reward i have joined whatever century it is we're meant to be living in (if i bump in to buck rogers i will know i have gone to far) and got myself a smart phone,
now my computer has been hitting that it is sick with pop up messages telling me that everything that computer thinks is wrong and strongly suggesting i back stuff up (it is back up) so i may have to get my self a new computer too
