I'm assisting a friend with a laptop that became non-responsive, with Windows not being able to load.
OS: Windows Vista.
AV: AVG 2011 Free (fully updated)
Windows Updated: not fully
I have gotten Windows to load with "last known good configuration". However, AVG warnings immediately reported - Trojan Horse BackDoor.Generic14.CCCR.
Steps I have taken, and results:
- Ran Spybot S&D (with full update and immunization applied), which only found 2 tracking cookies.
- (updated and in safemode), Ran Malwarebytes, which detected 219 objects. Selected to fix and was asked to reboot. Upon Windows reboot, received the following AVG warnings: Trojan Crypt.AQLW, as well as win32/Sirefref.ER
- Ran Combofix, which stalled at "scanning for infected files" step. I terminated scanning after it appeared it was stalled after 60 mins.
- Another attempt at running Combofix, with same results.
- overnight, Ran Malwarebytes again in safemode, which reported 219 objects. Selected to fix and was asked to reboot, and program hung without rebooting.
- Windows Update, reports 5 important updates avail, and 7 optional. I have just finished trying to apply the updates, but after 30 min. screen turned blue with "Windows encountered problem" (not sure on the exact error message), and system reboot.
Request: Can someone please tell me how to rid of these particular Trojans?
