Customer came in with a computer running slow. Updated and Ran Malwarebytes. It found 5 "Mywebsearch" and another minor one. Upon reboot, the computer has been cycling on and off, including all the safe modes. Choosing "Disable automatic restart" I was able to get a BSOD. It was PAGE_FAULT_IN_NONPAGED_AREA with a stop 0x00000050 (0xf7400c1a, 0x00000008, 0xf7400c1a, 0x00000000) and then two copies of
**** iastor70.sys Address F7400C1A base at F73F7000, Datestamp 00000000
I ran MEMTEST for one cycle and than ran SPINRITE level 5 overnight with no problems seen. I then Ran AVG rescue CD and it found 5 trojans and then also booted to a rescue disk and ran a CHKDSK /R . The only progress made in solving this problem is that I now only have one copy of the iastor70.sys message. The computer still recycles and I still get a blue screen of death. I even replaced the PSU just in case with no effect.
