Hum..vc nao leu seu squid.conf neh??


# These hosts are banned
http_access deny banned_hosts
# These hosts do not have any restrictions
http_access allow unrestricted_hosts

....

# Custom options (BRONCA AQUI #########################################)
acl blockext url_regex -i \.scr$ \.pif$ \.bat$ \.cmd$ \.lnk$ \.vbs$ http_access
allow unrestricted_hosts !blockext
 ...

se vc liberou la em cima não queira tentar bloquear agora pq não funciona
neh :p

Se não conseguir fazer dessa forma, use o que o irado acabou de falar...
