Got this infection on the laptop which when in windows will not let you access anything and says in short along the line of this programme is infected. I will have the laptop here shortly try to solve over the weekend.
He says he is unable to install any of the tools I recomended like SuperAntiSpyware in Safe Mode, looked in MSCONFIG and nothing untoward in there which would look like a dodgy loading programme.
So how could we get control back of the XP Home SP3 if when in windows nothing will run or execute. Any tools maybe that will run in safe mode maybe.
As for RKill it's a program created by a forum member of Bleeping Computers and has no guarantee to work on any PCs as the author states. Only for the availability for Malawrebytes to possibly run. Is that not so?
The whole point of having antimalware/virus on a flash drive is to be able to boot in safe mode then once Windows has booted with minimum msconfig then you use an external drive (connect to, after boot-up) to try and run the anti vir/mal scan. If that fails then Taff™ will have the answer hopefully.
