ty nemozes najst riesenie a google ho nasiel za 2 sekundy:
Trojan Generic KDV 792778, it pretends to be the windows service "Search Indexer" and it creates the fake executable: "igfxupdate.exe" which tries to connect in internet and rises the cpu load all the time till you open the task manager to hide itself..
So I solved the problem like this:
in the windows services management console I disabled the above fake windows service (it was in automatic start mode) and after I deleted the igfxupdate.exe file that was in the windows system32 folder..
I rebooted the pc and I deleted the same service with the command: "sc delete SearchIndexer"..
problem solved! cpu back to normal level, not more unwanted connections and not more igfxupdate files around ..
