I am not 100% certain, but I think that the "vindows" files could well be a the work of a virus. Do a virus scan - if your antivirus doesn't pick up on them, try the free Trend Micro House Call virus scan online:

I have used it many times before and it's safe for your system.
Please let us know if this helps or not, and while you wait for the scan to complete why not post in other topics around the forum?
