Hi, I'm new here.

I was wandering if anyone could help me?
everytime I log on, I type in my password for my user, then I get an rundll32.exe - application error saying,

"The application failed to initialize properly (0xc0000005). Click on OK to terminate the application."

After this, it shows my wallpaper and nothing else, sometimes everything loads after a while, but usually nothing does so I have to start something from task manager before everything else loads.

I have AVG anti-virus 7.5 and have run and removed all the infections found but it keeps coming up.

Could Someone please help me out seeing as this is real irrataing and I would really appreciate any help given.
Thanks.
