Title: Unable to update Avast virus definition and program
Post by: terminator53 on March 24, 2010, 06:45:23 AM

Hi all,

I am using Avast anti virus program version 5.0.377.

When i first installed it in my PC( In jan 2010) it used to give me updates properly.

But recently i un-installed it and again tried to install it. But it was not allowing me to install it again saying beta version is expired. So i changed my system date to previous month and successfully installed Avast.

But now when i try to manually update Avast it shows me following info.

Engine and definitions - already up to date(current version - 100318-1)
Program - already up to date(current version 5.0.377)
Total time - 10 s
Download time - 1 s
Downloaded file - 0 (0.00kB)
Server - unknown(unknown)




I don't know why server is shown as unknown

I have windows XP with SP3

Kindly please help me out.

Also i have one virus and i don't know how it gets triggered. While shutting down my PC i can see one process named 'No title" which windows xp try to end.

Any one aware of this virus as Avast is not capable of catching this virus.


Thanks in Advance

5.0.377 is an older version of avast!, so I suggest to uninstall it and install the latest version, 5.0.462.

Also, you should install avast! from scratch,

1. Download the latest version of avast! Uninstall Utility (http://www.avast.com/eng/avast-uninstall-utility.html) and save it.
2. Download the latest avast! (http://www.avast.com/free-antivirus-download) version and save it.
3. Uninstall avast from Control Panel (if possible). If, for any reason, you can't run it, try booting in Safe Mode (http://www.pchell.com/support/safemode.shtml) and doing it from there. Anyway, boot after that.
4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can't run it, try booting in Safe Mode (http://www.pchell.com/support/safemode.shtml) and doing it from there. Anyway, boot after you've run it.
5. Install avast! using the setup saved on 2. Boot.
6. Register your free copy or add the license key for Pro.

@ terminator53

Please don't post multiple posts for the same problem, all this does is cause duplication of effort for those trying to help, I replied to the first post you made 3 minutes before this one. http://forum.avast.com/index.php?topic=55733.msg484986#msg484986 (http://forum.avast.com/index.php?topic=55733.msg484986#msg484986)
