I am currently backpacking in India for several months and have to use public PC to check my email and write my blog.
The first thing I do when after I plugged in my hard-drive is to use SysInternals' Autoruns.exe and procexp.exe to check for unusual software on the machine. In many cases just starting them kicks into a hard reboot without a blue screen.
I had this experience before and it is usually malware on the system that detects these programs and initiates the reboot.
However I had this problem on so many PCs now including some newly set up ones that I don't think malware is the problem.
This usually happens on Windows XP.
I tried this from different media to make sure there is no problem with the drive.
I am sure the copies of autoruns and process explorer and clean and I am in some cases 95% sure the PCs are clean too, but the reboot still happens.
Any ideas what could be the cause for this?
On my hard drive I have a boot-able Ubuntu Linux which I use whenever I can because I feel much safer using it. But I am not sure what tools to use there to check for malware on the Windows partition.
