During recommended update to version 7.5.503 AVG Free Firewall Driver can be offered to be updated. This does not mean that AVG Free contains firewall component now. There is only new driver (which is common for email scanner and firewall) used in this build. This behaviour can occur on Windows Vista, when AVG 7.5.441 or older build is being updated.

Some viruses hide themselves by doubling their file extension. For example, the VBS/Iloveyou virus attaches a file, ILOVEYOU.TXT.VBS, to e-mails. The default Windows setting is to hide known extensions, so the file looks like ILOVEYOU.TXT. When you open it you do not open a .TXT text file but instead execute a .VBS script file.
