i am using avast 4.8 home, the downloadable version. i cannot update it, it says that there is error in connection or it cannot connect to download95.avast.com
do you use any other security program (antivirus, firewall, antispyware)?
how do you connect to the internet (dial up,…)?
Please, post the last 200-250 lines of avast log: C:\Program Files\Alwil Software\Avast4\DATA\log\Setup.log
