Fixing a startup driver error

First off, I'm not sure I'm posting this in the right forum. Please no hard feelings, wasn't sure what topic to post it under.
I'm fixing a computer for a friend and I had removed AVG antivirus from their computer due to them have (2) anti-virus programs running at the same time.. The Resident AV is Microsoft Security Essentials. In doing so, I have come across the problem of the computer hanging up upon startup. Sometimes it will start without a problem, other times it will freeze.. may get a BSOD, may not. Always during startup though I can see in the even viewer there there is an error with a driver remaining with AVG anti-virus. Error in viewer is: Service Control Manager

The following boot-start or system-start driver(s) failed to load:

AVGIDSHX

i8042prt

I have searched some on the net and cannot seem to remove the driver myself. If anyone can give me some tips to remove this said driver or file so that the computer will start normally again, I would really appreciate it.

Thanks

"i8042prt" This is a keyboard/mouse driver. Is this a laptop? Did AVG uninstall properly and completely?

No this is a desktop PC. I have a plain logitec usb keyboard and mouse attached to the computer. And yes I uninstalled avg from the add remove programs menu.

So are you still getting the start up errors?

Yes it only happens occasionally.

Sorry for the slow replies im at work all weekend. I already had it uninstalled before posting this thread

So you ARE still getting these start up errors?

>>>>>>>YES<<<<<<<<<

The computer may be infected with malware:
AVGIDSHX
IDS Application Activity Monitor Helper Driver. You uninstalled AVG, but this is part of AVG still being flagged by Windows. Can you do a "clean" fresh install of Windows?

No. There is too much pics/ info/ programs to back up without getting an external hard drive. Also the pc isnt mine so that would be an extreme decision. That is an obvious fix but a last resort.

Please dont close the thread if I dont answer you back quickly. Like I said earlier I have work all weekend so my time to run logs and such is very limited. Thanks for your time and patience

How about backing up using a flash drive or DVD?

You can try AVG uninstaller. I had the same problem on a computer a while back when I removed AVG. The computer kept blue screening, You can get it at. www.avg.com/us-en/utilities It work for me. It may or may not. Can 't hurt to try.

Yeah, I'm such a fan of doing a fresh install of Windows. There are so many that don't back up important data regularly. Now days it is so easy to do...

Is it something that cant be fixed easily? Reformatting seams like an extreme option

Have you tried using the AVG uninstaller Cobalt006 posted? AVG stuff is clearly still on your computer. Try this temp file cleaner:

..and you said nothing about a possible malware problem

Did you try the AVG uninstaller?

Yes, that seemed to help. I also ran the cleaner and computer seams to be running much better in terms of speed honestly. I still see a service controll error in the Events viewer though. {i8042prt} is the driver error still.. You said earlier that it was due to a keyboard or mouse issue. I only have a Logitec keyboard and mouse connected to the computer though. They didn't come with any type of driver software. Unless windows failed to load drivers for them maybe??

I don't see the AVG driver error in the Events log. I restarted the computer several times and no BSOD. I would still like to get rid of the error I just mentioned above though if possible. Not sure if there is a fix for it though

If you are running a USB keyboard . You will get this error if your PS2 port is still active. It really will not hurt anything, My old computer had it from the day it was new, Because I did not use that port, So what I did here not to long a go was go in the Bios and disable My PS2 ports. After that I never got that error again . You may or may not be able to do this depends On what type Bios you have and what make of computer, Home build or Retail. There are other ways threw the windows registry, But I really don't remember them off hand. If you click on the error It should show you a link from Microsoft they may help you out with a solution. Or Maybe TMagic will know one.
