ALL my Win7 64bit computers CRASH after Avast7 FREE Upgrade.

Avast Free Antivirus / Premium Security
1

I’ve seen posts on this on the internet after Googling. I have emailed tech support. After having to use a restore point to get the computers back up, Avast cannot restart due to a .dll problem.

I did the Upgrade … I restarted the computers. I logged in with my password. Then the computer stalled: blank screen with cursor. I gave it 25 minutes, believing it was doing some sort of configuration. I tried this 5 times. I gave up and went to a restore point 2 days ago and my systems restarted just fine … but now Avast won’t work.

Is there a fix for this? I had been enjoying using your virus protection but now I have none. If you can’t lead me to a fix I will have to install other virus protection.

Sad.

  1. Download avast! Free Antivirus: http://files.avast.com/iavs5x/avast_free_antivirus_setup.exe
  2. Follow instructions: http://www.avast.com/uninstall-utility (Run this tool for all prior installed avast! versions…!!)
  3. Reinstall avast! with the downloaded installer from point 1.
  4. Reboot.

How many computers are those “ALL my computers”?
Is there any common 3rd party software installed on all of them… or any special configuration/settings… anything in common?
Thanks.

4 computers … ALL run Adobe CS5.5 Master Collection, Thunderbird, Firefox, CUTEFTP PRO, WIN Office 2010, Rhapsody Premium, Skype

No “garbage.”

All get full virus scans, disk cleanups, weekly restore points … ie. well maintained.

They are all DELL Core i7 with 8GB RAM and 3GB graphics cards. JBL Acoustics …

Avast has not cause a single problem until now.

I’m going to do what the last Avast rep suggested and see how it goes. Will get back to you.

OK … I just followed ALL of Asyn’s instructions … exactly. I can login but then I am stuck on the blank screen with cursor and Windows will not finish the startup. Still crashing.

Got any other ideas or do I need to get other Virus protection? :frowning:

8

Is there any access to the PREVIOUS version (the one before I did the upgrade)? That worked.

9

Which AV did you use before avast!..??

10

Yes. → http://www.oldapps.com/avast_antivirus.php?old_avast=7370

I installed Avast 6.0.1289.0 on 9/20/11 … I have been installing ALL the suggested updates and upgrades since. This last one will not work on my system.

I hope Avast will fix this. I’ve been using Avast ever since the old interface with the Star Trek console look. :frowning:

12

If so, did you really run the uninstall tool for ALL prior installed versions in safe mode…??

13

Always. There is just something buggy/incompatible with the latest version. I am installing 7.0.1426 now and will let you guys know how that works out.

14

By that way. I Googled this problem. I am not alone. I’m happy to offer whatever info I can to help you resolve this.

The problem is ONLY with this latest version.

15

Thanks, but as you’re going back to the old version…
Maybe Igor has a better idea…?! :wink:

16

Thanks Asyn! Going back to 7.0.1426 (legacy version) works … for now. Clearly there is a bug with the new version as I can get the same repeated results trying to install on my Win7 64 bit systems. As I have mentioned, I am not alone. This is getting posted on the internet in other forums.

As for Igor … you’re the only one who is offering any helpful advice so far … which I am grateful for. ;D

You’re welcome.

It’s Win 7 x64 specific, liz. It doesn’t affect everyone, and it’s not always the same problem, but there does seem to be a problem with 7 x64. On my dual boot machine, Win 8 is fine, but 7 had boot problems with v. 7.0.1456 Free. Once I uninstalled Avast everything was fine. (http://forum.avast.com/index.php?topic=101081.0)

I’m kinda upset about it. I feel betrayed. I hope they figure it out, but from the comments I’ve read, the question everyone seems to be asking is “what have you done wrong?”. There is nothing more infuriating than that.

Funny >:( I have a W7/64 bit machine that upgraded like a charm.
It is my XP Pro SP3 that gives trouble.

A bit off subject. I’m sorry to say. I bought a 2-yr Avast for our two computers after initially having had the Free version. At the time, I had and used a different email address. After that address was hacked, I changed it. My 2 yr contract goes until June of 2014. I need to know how to contact Avast and get the new email address connected to our paid 2 yr contract. No telephone number (the simplest way) appears anywhere I can find. Please help!
