avast 4.7 home intalation problem

PetrB · 2007-02-27T09:02:51.000Z

Try to download Avast uninstall utility from http://avast.com/eng/avast-uninstall-utility.html .
Then install latest version of Avast again. A ball Avast icon should appear in your system tray. If not make shortcut in your start up folder as advised you DavidR before.

Hi i think you have a root virus since my avast dissapaired the same way. so i tried the f-secure blacklight and panda anti rootkit to remove it.
I also tried to uninstall and install and after reboot it couldnt find the ashdisp.exe
So hope you will be more lucky to solve this problem since im still trying :-[

Hi!

I was removing avast with the tool from avast web site. Othervise it was not possible. Regarding F-Secure: I was trying to install this as well but without luck. Also NAV ???

It looks like I’ll have to foremat my PC. F…!!!

If you are having problems installing other AVs it could well be a rootkit killing them.

What were the problems in trying to install or run these ?

You need to exercise care if you installed NAV this can be very difficult to remove at the best of times and when you clearly have a problem possibly more so.

When you click the Change/Remove you should get a pop-up with other options, see image.

Well, when installing other AV’s simply nothing happened. It looked like none of them were installed. During installation of NAV some kind of error was displayed. In case of s-secure the installation process started but… nothing happpened. Any icon on desktop and when I opened it in Program Files there was no startin icon. In case of the other AV’s the installation procedure didn’t even start at all.

system · 2007-02-27T18:42:04.000Z

I tried to click Change/Remove but there is no pop-up. Funny, 'cause on my laptop it works . I am pretty sure this must be this f…n rootkit shit. Appology for my words, but it annoys me very much. To say it diplomatic

system · 2007-02-27T18:44:54.000Z

when I click change/remove button on my pc the small window with: choose the language appears, than avastAntivirus setup. Nothing more.

DavidR · 2007-02-27T19:17:15.000Z

You certainly seem to have other operating system problems that are complicating the problem.

Can you boot into safe mode ?

If you can try installing the anti-rootkit tools from there.

system · 2007-02-27T20:01:48.000Z

ALLELUIA!!! VICTORY!!!

Panda did manage it. I men the panda root remover or somthing like that. I checked the links you indicated and simply followed. And it managed. UFFFFFFFFF!!!

Thank you Mr. DavidR for your patience and help. I relly do appreciate it. Maby one day I’ll be able to pay back

Which software can you recommand to install on pc to protect against adaware and spyware??

system · 2007-02-27T20:11:35.000Z

f…

To early! Strange! The icon on desktop is the ‘a’ icon. After reinstalling avast full scan of discs was performed. I thought it works O.K. now. But… when I clicked this desktop icon still the same problem, still no icon in task bar bottom left and still cannot find .exe :-[

DavidR · 2007-02-27T20:40:50.000Z

Do you have a firewall ?
One that provides outbound protection and XP’s (if that is what you have) doesn’t provide any. Without a firewall you will be fighting an uphill battle to remain clean.

Did you read these other forums I gave previously as they would appear to have the same problem ?
See http://forum.avast.com/index.php?topic=26554.0 and
http://forum.avast.com/index.php?topic=25941.0 this topic also provides links to on-line scans.

For software, just look at my signature that I would say is a good start point.

It looks like the rootkit is still at large, so you should also install and then run the other anti-rootkit tool.

system · 2007-02-28T01:10:57.000Z

Now that Panda has done some cleaning it may be worth trying to install BlackLight again. If it still won’t, see if an F-Secure on line scan will help

well, now I am in deep s…

I tried to boot my pc in a safe mode - no success. So I did this:
Start Menu, Run, typed MSCONFIG, OK, IN BOOT I selected Safe Mode, and…

And now I cannot restart my pc. It is looped!!!

Is there any solution? I mean to start my pc?

DavidR · 2007-02-28T14:08:17.000Z

I’m sorry I have never experienced what is happening, but I wish you would have run it by us what you were going to try, I certainly wouldn’t have used this msconfig option as the only way to change it is to be able to get in and run msconfig again, so if you experience a problem you are trapped.

This suggestion is also fraught with possible consequences, but you are between a rock and a hard place with few options remaining.

If you are able to boot into a DOS prompt rather than into this loop you might be able to edit boot.ini and remove the /safeboot that you added. If you screw up the boot.ini file you are royally screwed.

It is a long time since I played with DOS so you should investigate making a copy of it just in case, something like copy C:\boot.ini C:\boot.old (this however, didn’t work for me since I was in windows using a command window, so the file was a hidden file perhaps that was why.

You could also try booting with the windows CD and try to get into the recovery console and try the last good configuration, that may correct the problem. You should investigate how to get into the recovery console (google search, etc.) and print it off before contemplating this.
http://support.microsoft.com/kb/314058 or http://www.kellys-korner-xp.com/win_xp_rec.htm

Both of the above options are ones of last resort I would suggest the recovery console first as you aren’t tampering with boot.ini.

system · 2007-02-28T14:29:39.000Z

Well, I was trying to boot this shit with CD, but there was an info that it doesn’t see any hard disc installed >:(

And I am not good in DOS at all. It looks like I have to go to some service :'(.

Anyway I’d like to thank all of you for your help. I just give up

system · 2007-02-28T16:40:05.000Z

Can you get into the BIOS?

system · 2007-02-28T18:53:13.000Z

Yes I can. At least when I press F11 it works. Or should I do something else?

At Bios, can you recognize the HDD or the bios does not recognize it?
Can you change the boot order and boot by the CD?

system · 2007-03-01T07:50:56.000Z

As I said, when I tried to boot from CD It says that cannot see any hard disc installed on my pc. My motherboard is ASRock AMD-VIA series.
