Hello, I am hoping to find some help here. I am constantly getting corrupted files on my Windows installs. A little background: About 2 months ago my laptop got a virus. I couldn't remove it so I restored my Win 7 OS using a WHS 2011 backup. In a few days windows found some corrupt file errors and corrected them with check disk but would not boot into windows (Safe Mode or even command prompt). I thought the backup might be corrupted so I did a fresh install of windows 7. After a few days windows ran into more corrupt file errors that would keep it from booting. So I thought my Win 7 install .iso might be corrupted, I redownloaded the .iso and did a fresh install again. Again more corrupt file errors keeping me from booting. Tried the Win 8 .iso and after a day Win 8 found more corrupt file errors but this time I was able to boot into Win 8. The corrupted files kept Win 8 from resolving DNS so no internet or network access. (Strange) The windows dvd's cannot repair the issue in any case. So I thought it is a hardware or driver issue. I installed Ubuntu linux and have been running Prime95 for the past 27 hours with no errors. These corrupt file errors only occur after some time. So everything is running fine, then I might come to my computer in the morning with an error message. My thoughts/questions: Is it possible that my WHS 2011 box is serving a virus to this laptop via its Connector app? If this is the case why is my other Win 7 laptop unaffected? If the hardware is fine why would my other laptop, which has all the same programs installed not have any problems? Linux runs just fine on that machine, which makes me think my problem is software and not hardware. Sorry for the long post, and thanks for any advice.
