Been running avast free home edition for 3 years, never had this problem before. I noticed this problem 2 days ago and since then every time I try to update it says:
“Invalid file signature. Setup will terminate.”
Nothing wrong with my internet connection and I have plenty of free space on my hard disk. Running Windows 7 Ultimate (x64).
