Have you got the same impression that when you only turn on your computer,
is performing all sort of tasks on its own and the last thing is doing - executing your application ?

Very often my computer is using 100% resources , since I didn't even open anything but single browser (there is no virus or rogue Trojan involved).

I suspect that nowadays , possibly big companies that provide software ( like browser or script running inside browser) managed to employ our computers to do their own computations remotely.

For example they could utilize all computers with specific browser ( or other common application) to do BitCoin mining ( or another task not related to our activity). Whole our computer network could be already hijacked to perform tasks for this grey or black cloud.

If that is the case and proven one day, it should be prosecuted and damages claimed for our lost productivity , time and electric and computer power.

Have you got this same problem with slow computer recently ?
