Antivirus programs cannot update

I have tried AVG, avira and avast none of these could connect to update servers, so I browsed some internet forums and downloaded malwarebytes, super antispyware, and A squared anti spyware. Malware bytes found 4 trojans when I scanned the full system using it in safe mode. the other two after that found nothing. I still cannot get the anti viruses to update. what should I do?

Then also have a look if you can find:

cant remove AskSbar

In reply to: C:\Program Files\AskSBar

I did not find Asksbar or AWS in control panel but I found AskSbar in program files. Vista is not letting me delete the folder. I turned UAC off but still when I try to delete the folder it says you need permission to delete it, I am already on an administrator account.what do I do? Sad

Try to remove it in SAFEMODE..........

still not working

In reply to: Try to remove it in SAFEMODE..........

I booted in safe mode and deleted the AskSbar folder but still no effect. I tried updating avast and malwarebytes but they won't connect, If I install AVG everything stops connecting to web even my web browser so I had to uninstall AVG. I don't know if its helpful but Super anti spyware has been able to update automatically throughout this thing.

I have updated Malwarebytes manually I got the definition from 3/24 not 3/25 I guess they haven't put up the newest ones yet.

MBAM has NEW updates.......

In reply to: still not working

I updated again and I now have:

Date 3/25/2009
Database version 1899.

Try Unlocker





to remove the "Ask.files".

Another thought:

Click on Start, click Run, and then type devmgmt.msc and click OK
On the View menu click on Show hidden devices
Browse to Non-Plug and Play Drivers and you should see something like


Highlight that driver and right click on it and select DISABLE - NOT uninstall.
Now RESTART your computer.

Does that help to update your programs?

In reply to: MBAM has NEW updates.......

I am sorry I wasn't clear. I meant no effect on updating not on Ask files. I did delete the Ask files from safe mode and no I don't have those files you listed under non plug and play.

formatted the whole thing

In reply to: Are you able to run an on-line scan?

I access my bank accounts etc from this pc so just to be on the safe side I formatted the drive and reinstalled vista. Thanks for your help. Can you please recommend what antivirus/anti spyware/firewall etc I should use to prevent infection again and should I keep UAC on vista on? its really annoying but if it helps I'll leave it on.thanks

Check HOSTS file

In reply to: Antivirus programs cannot update

Depending on the malware, it could have corrupted the DNS host file which would cause the AV update process to not function.

To find the hosts file, look in: windows->system32->etc->drivers

Open the "hosts" file in notepad. If there are additional entries other than " localhost", it's likely malware got to it.

Copy the hosts file to another name first just in case and delete those other entries out of the origional file. Save and try the update process again.

host file

In reply to: Check HOSTS file

in the host file other than I found a lot of entries which were put in by spybot search and destroy. These were safe I guess but I deleted all of them anyway, still can't update.

Let's try avast

In reply to: host file

There is malware which directly targets AVG and turns off the update service creating a domino effect taking out the whole program. Then you can't get to the web at all. If you can access/download the file from this URL:


it maybe possible to manually update avast. Make sure to say YES to scan on next reboot.
