Repair Avast!
With XP
Start > Control panel > Add & Remove programs > select avast! and click " Change/Remove ". Look for " Repair " and click it.
With Vista or win7
Start > Control Panel > Programs > Programs & Features > uninstall a program > select avast! and click " Uninstall/Change ". Look for " Repair "
Reboot when finished.
If it is still sending samples to Virus Chest after repair, I am afraid that you would have to do a clean install.
Good luck.
