wtf antivir

hello friends, need some help:

yesterday I decided to install an antivirus program, to scan my pc once again, as I had some random crashes and startup-fails during last days

so, I decided to go for avira antivir, installed it -> the program failed at updating

I thaught wtf crapprogram -> uninstalled it

so I went for avg free 8.0, which I've been using before I decided to uninstall all securitysoftware

but now, also this program is failing at updating:
both antivir programs I've used weren't able to properly update through the built-in updater

smells like virus :D

so, I ran avg with the defaultcfg, it detected 6 threads or something, all solved.
still not able to update.

MY QUESTION IS:

could some kind person please upload his latest update file from avg free 8.0 ?
the avg website faq doesn't help me, and I downloaded everything related to manual update from there, didn't help.

THÄNX
