It is not just the NSA, who plays with your computer

It seems that not a day goes by without someone ruining a moment (while watching a movie stream, while developing software, while learning by reading pdf-files, while browsing Flickr, while writing email etc.).

That someone can see what I see on my monitor screen and that someone can remotely trigger anything that the operating system's APIs allow (bypasses OS's User Account Control). It might be something simple like changing keyboard language from FI to EN or harddrive starts defragging out of its schedule. Typically there are phases of few months when only certain tricks are used for irritating me and then, suddenly, one of them gets replaced by another trick.

As that someone can see what I see, it is possible to do something irritating by timing it very accurately like crashing the Flash-plugin while I am listening music via TuneIn. That someone can act as an invisible virtual user and do something like make my mouse pointer to move quickly to some corner or make it follow more complex paths (like an arc and with a varying speed).

Very worrying is that that someone can hear in real time, what is been said in a chorus of a song, and that someone can freeze my computer at the moment, when there is something symbolic in a movie that I was watching. It is very typical that symbolic thing is something that is related to an "offline event", which occurred some time before (like to a moment in library a few hours ago). This means that atleast one of the attackers live in the same city than me. Generally, it seems that the attackers have collected lots of data about me, which is partly derived from the way I use my computer and the Internet.
