Blue screen of death after installing avast

I just reformatted my laptop so i reinstalled avast

however right after i installed it i encountered a blue screen of death, now every time my laptop loads up it encounters a blue screen of death. this has never happened to me before and i’ve used avast for a good year now

anyone know what’s going on???

my laptop is running on safe mode right now and i really have no idea on what to do…

when you say reformat…do you mean a clean install from disk?
or recovery back to factory install?

i did a recovery to what it was out of the box

Did you by any chance ever install Ad-aware Free with Antivirus? That one had one nasty bug that made all other antiviruses BSOD on installation…

so then you have also reinstalled the factory installed antivirus?
like norton / mcafee / trend micro ?

if so it must go before installing avast

use removal tool to clear any leftover files that conflict http://singularlabs.com/uninstallers/security-software/

i don’t even know what Ad-aware Free with Antivirus is so i’m pretty sure i haven’t installed it

as for the preinstalled antivirus programs, my laptop did prompt me to activate Norton Internet Security which i refused but it somehow is still on here…

in any case i uninstalled avast while in safe mode and restarted normally and now the BSODs have disappeared =/

should i get rid of Norton Internet Security before reinstalling avast?

Yes…never install multiple AV

and find the tool at the link i gave you an run it…

alright thank you

I also found Norton Online Backup installed onto my laptop, should i remove that as well?

also would i need a special removal tool to remove that as well or can i just uninstall it like any normal program?

EDIT: Nevermind, found that you can uninstall it normally and I did just that.

anyways I really appreciate your guys’ help! =]

You will still be required to run the removal tool from the link that Pondus supplied you to remove remnants of norton before installing avast, then i would also run searches in your system for " Norton " - " Symantec "

It kust happened to me but all seems okay right now…

Thanks, Pondus, for that link. I registered for the forum to come say so. I had removed Norton prior to installing Avast on this laptop (XP), and I got the bluescreen of death after install too. I thought this cleanup would help, but unfortunately, upon reinstall, it still gave me the bluescreen. I just ran Ccleaner (after again removing Avast in safe mode, and the registry cleaner found a bunch of Symantic entries. I may try installing again, but, if it doesn’t work, any further ideas? I have never had this problem with Avast before, and feel neked without AV. Thanks for your expertise.

What OS are you using david?
