Update

Hi. I’m posting here 'cause my avast! free antivirus tries to update its virus database, but it’s failing once and once.
It has been doing the same for about two months. When I try to do it manually, it simply says “total time: 2s”. The same problem with program version. It’s like a lost conection with update server.
Should I reinstall my antivirus? Or what?
Thanks.

Install from scratch:

Very important to remove all remains of other AVs installed before Avast. Use this site to execute uninstall utilities for other AVs.

Download and save to your desktop aswclear : http://www.avast.com/uninstall-utility

Download and save a fresh copy of Avast!. Be sure to have your lincense handy if running a paid version:

http://files.avast.com/iavs5x/avast_pro_antivirus_setup.exe
http://files.avast.com/iavs5x/avast_internet_security_setup.exe

Use aswclear in safe mode once for Avast! 7 and any other Avast! you may have had before. Reboot after each uninstall.

Reinstall fresh copy of Avast!

Reinstalled, but it says “invalid signature archive” when I try to update it.
By the way, I’ve seen another post about the same problem, where you recommend to download VPS. Should I do it?

Did you do it running aswclear in safe mode ? Did you run the uninstall utility for whatever AV you had running before Avast! ?

What firewall are you running ?

By all means. You will have an up to date Avast!. Reboot afterward.

Yes, I removed ALL its components with aswclear.
What a rarity. Yesterday it didn’t want to upload, but I’ve just tried it again 2 minutes ago and it uploaded correctly.
Repared… I think so.
Thanks!

Busy servers ? :o

You are welcome.
