I've recently been asked to look at a teacher's laptop that she stupidly allowed her kids to use during the holidays. It was riddled with viruses
and I suspect has corruption in the OS.
Using a variety of tools (CWshredder, removeit pro 7, Macafee stingers, Malwarebytes MAB, vundo fix, AVG) I found 25 different mentions of Virus and malware including virtumonde. After removing these, the processor loading has now reduced to 4% so I'm hoping it's clear now. However the laptop is still very slow on start up and I don't know if this is due to corruption of the OS by viruses etc, or I still have viruses in there somewhere.
Boot.ini is missing and bootcfg /rebuild won't work due to 'corrupt files' it says. A repair install is not allowed by the OS. The owner of the laptop doesn't want a rebuild if possible as it is actually owned by the school and she could get into trouble.
Do you think I could have cleared it? Thanks for your help
