Edit: poster is familie, vandaar mijn edit. De laptop geeft melding van een antivirus IS, met pop ups en uitschakeling van functies. Opslaan van documenten lukt niet meer, programma's openen of wijzigen ook niet. Alles werkt wél nog onder het gast-account. (alwéér gijzelingssoftware dus!)

Hoi, ;)

Voor alle tools geldt -> Rechtsklik uitvoeren als Administrator.


1.


Download TFC (http://oldtimer.geekstogo.com/TFC.exe) en sla deze op je Bureaublad op.

Rechtsklik TFC.exe 'Uitvoeren als Administrator' om het programma te openen.
Het programma zal alle andere programma's sluiten, zorg er dus voor dat je al je werk hebt opgeslagen voordat je verder gaat.
Klik op de knop Start om het programma te starten. Hoe lang het programma nodig heeft, kan verschillen. Dit kan kan slechts een paar seconden zijn, maar ook 5 minuten. Laat het programma gewoon ongestoord zijn werk doen totdat het klaar is.
Als het programma klaar is, dan zal het je computer opnieuw opstarten. Als dit niet gebeurt, start dan je computer handmatig opnieuw op
