In de opstart procedures vond ik de file wuauclt.exe

[Prutser]

In de opstart procedures vond ik de file wuauclt.exe. Bij nazoeken op net in www.bleepingcomputer.com stond dat deze ongewenst was. Deze acie uitgeschakeld en daarna gezocht waar deze stond. Vond hem in de windows\system32 dir. Ik kon de file renamen maar tot mijn grote verbazing verscheen na enige seconden de file weer als een nieuwe in verkenner . Is dit een probleem of een mis-interpretatie. Het progje staat te boek als een opstartfile van firefox.

Hierbij tevens log.

Hallo Erik,

Als ik op BleepingComputer kijk ([url=http://www.bleepingcomputer.com/filedb/wuauclt.exe-3139.html]deze link) zie ik dat dit proces van Microsoft zelf is. Wuauclt.exe is verantwoordelijk voor de Windows Updates.

Er staat echter op de pagina dat het bestand in de dllcache map staat, maar de dllcache map is een back-up map van belangrijke Windows bestanden. Als er een belangrijk Windows bestand aangepast wordt (door bijvoorbeeld malware) word deze door de Windows File Protection (WFP) teruggeplaatst vanuit de dllcache map.

Je kunt ook altijd deze site gebruiken om bestanden na te kijken:
http://www.liutilities.com/products/wintaskspro/processlibrary/wuauclt/

Je logje ziet er overigens helemaal in orde uit, nergens om je zorgen over te maken dus
