I'm not certain at this point if there is some sort of conflict or if it is an infection. The login screen rapidly blinks (black to normal), the text and video appears corrupted and nothing responds to mouse clicks or keyboard.
Using: Windows XP Pro, HP Pavilion Notebook computer
Here's what I've done so far. I started by using a Norton Ghost live boot CD to backup the existing partition so any work I do can be reversed. I was able to boot to safe mode and all is well. I tried "diagnostic boot" from within msconfig which basically shuts off nearly all non essential services, progs and init files. This unfortunately doesn't rid me of the blinking bootup problem.
The computer already has AVG 8.5 installed and has been running consistently even when the problem began. From safe mode I tried installing and running the latest Malwarebytes Anti-Malware. This found no problems. Being I have a backup image I tried running combofix as this has saved me in the past. Combofix complains that AVG is running in safe mode despite the fact that no avg processes show on the process list and the one AVG service listed in service manager is now disabled. I tried to uninstall AVG from safe mode but the uninstaller quits with an error stating it could not make a registry key. So I can't uninstall it. Combofix ran anyway, installed recovery console, but failed to fix the blinking problem when booted normally.
I still don't know if this is malware or a conflict but family members claim no no software of any kind (including drivers) were added recently. The combofix log does mention finding a file called deploytk.dll but the file now appears to be removed and the blinking problem persists.
I'd post hijack this and combofix logs but the instructions say this forum is not for HJT logs so I'm not sure how you'd like to proceed?
Again, just basically want to determine if this is malware or conflict and how to fix it.
Thank you in advance for your time!
