Invalid Signature on Update

[MediaGuy1974]

Hey Gang I'm Back,Had a problem earlier that some of you helped me solve(a fragment of mbam was keeping Avast from installing). Now, with Avast up and running, I'm trying to update it, and both the program update feature and the definition update feature keep reporting an "invalid signature" and neither will update. Anyone seen this before? This is a fresh install of XP with basically only Office 2K installed, and nothing else. Any ideas??

-WinXP Professional Fully Updated, Athlon 1.2, 1GB Ram, 80GB HDD, Radeon 9800, Avast 6-

This is a fresh install of XP and Avast, and basically no other software installed.

Sorry in Advance for not posting a proper subject. I clicked "post" before I realized what I'd done. It won't happen again.

You can edit/change it still, if you like.  (see "modify", top right corner of each post)

edit: you have to alter the original post

Welcome.

As to your problem, have you rebooted yet since you installed?

[MediaGuy1974]

Yes, rebooted 4-5 times. It's not the computer I'm on now, but I just went in and shut it totally down, waited 5-mnutes, started it up, and when it loaded Avast it downloaded the definition file and seems fine. Don't know yet about the program update. I'm gonna let it be for a while and try again later. I'll keep ya posted. and THANX!!!

Hopefully just a hiccup, then.

Glad to help.

  Well, I just tried to manually do a program update. It downloaded for a minute, then popped up with "package broken". I don't get it. I've never had a problem installing Avast.

This might be a server problem also.

If that is the case nothing local is going to fix anything, you would just have to wait it out.

If you just installed avast, then what would be the point on performing a program update? I mean, you used the latest stable version of the installer, didn't you?

In any case, you should try avast main GUI -> settings -> updates -> "direct connection (no proxy)".

I recommend an update after installing because there usually is an update.  The definitions are always changing (at least 2/day on average), so the download file will not have the latest update definitions.

In any case, you should try avast main GUI -> settings -> updates -> "direct connection (no proxy)".

Agree.  Let us know how this works for you.  Also check to see if anything else is trying to download at the same time (is your firewall or MBAM Pro trying to update its definitions at the same time?).

@SafeSurf,

The OP is talking about a PROGRAM update, not the definitions update (which was already done). Hence my question is still relatively relevant. I mean, it was the latest stable version already that was installed.

In any case, the "no proxy" setting is the one I would try first, and if that is not enough, I would delete any avast - related firewall rules and reboot.

Only if those possibilities are not enough, I would try "more drastic" meassures.

My error.
