Ok I have multiple systems running at my house. Right now the only one that works flawlessly is the one which runs XP (Go Figure). The system I am having issue with is my Wife's netbook, it is a Toshiba NB505. It has windows 7 starter loaded on it. It has the following hardware (if it matters) - Intel Atom processer, 250GB Hdd, 1 gb memory (still it is slow as molasses in December) I figured I had acquired some sort of excellent backdoor/rootkit/trojan jobby when every google search was redirected, after a day with it my AVG wouldn't work, uninstalled it, reinstalled MSE to no avail. Then ran Malwarebytes, kept finding the same issues, unable to clean/quarantine even whilst being ran in safe mode. Finally decided to download the Kaspersky Rescue Disk 10, ran it, it allowed for multiple items to be removed/cleaned however upon restarting I get the aforementioned issue of "Windows has encountered a critical error... etc" From here I have done: Tried to create a shortcut of shutdown -a on my desktop - doesn't do a thing. Problem persists in Safe Mode, only have 1 minute to try and find an event log. I have continued to run the Rescue disk and have found nothing on the system, ran the mem tool associated with Linux/SLAX and all physicalities checked out A-OK! Today I downloaded and copied to a pendrive hijack this, windows KB-890830.exe patch but have not applied them yet, as I do not want to run any further down the rabbit hole. I also have Avast but as I indicated, even running a USB based scan I find 0.0 viruses on the computer. Seems like I scrapped a .dll or .sys file that I shouldn't have in order to remove the root that was a pain. As this is a netbook there is no windows CD to use, because it didn't come with one and doesn't have a cd drive. Furthermore I am much more likely to scrap windows 7 in favor of a ubuntu based OS if I cannot patch this easily. As a reminder, Safe Mode and Safe Mode Sans Networking still allow this issue to persist. I appreciate any and all help!! Best Regards!

Ok well I've done a bit more reading and I'm going to try the KB-890830 patch to see if that works, roll the dice! - Thanks Me.

Hi, Would you please let us more details about the issue. Do you mean that the error Windows has encountered a critical error occurs every time you try to reboot your laptop? Please also capture screenshots about the issue. Also, please try to run the System File Checker tool and see how it works. Hope this helps. Jeremy Wu TechNet Community Support
