Very little. I opend both machines with Resurce monitor. The one with possibel mallaware had a huge number of files running, the other one not. Opend IE to see Gauci could be, and I risked and suspended Gauci. The list of runing files reduced to minimum and the blue diagram disapered. Now waiting to se results I had he disk Defragmenter on as well. Defragmenting finished in a sec. Opened IE, and my documents, and folders opened ina sec. much faster then ever.
