avast!: The AAVM subsystem detected a RPC error

Hi!
I have recently installed avast! Antivirus Professional Edition 4.8.1229. It all worked fine. I rebooted the computer and had a full scan, found some infected stuff, I told it to delete it, etc.
Whenit all was over, I got the avast icon barred with a red line down on the taskbar next to the time and date. It says: avast!: The AAVM subsystem detected a RPC error.
I went to the link they told me to go (the FAQ) : http://www.avast.com/eng/faq-red-circle.html
I updated my Windows components, then did what they said. But when i try to start avast antivirus, it says: Error 1053: The service did not respond to the start or control request in a timely fashion.
I tried to repair avast, but i still have this message.
Can you help me, please???
I read on other topics that I had to uninstall all other anti viruses. I had AVG and Kaspersky before, but I uninstalled them. Maybe there are some files who left. What do i do to find them and delete them?

Please help me. Right now my computer has no protection and Windows doesnt stop to tell me that I dont have an antivirus.

Thank you in advance :slight_smile:

First - Deletion isn’t really a good first option (you have none left), ‘first do no harm’ don’t delete, send virus to the chest and investigate.

The error is also associated to either having another AV installed or remnants of one left after uninstall.
Have (or did) you another AV installed in this system, if so what was it and how did you get rid of it ?

I had AVG.
I uninstalled it, then rebooted.
How do I verify if there are any remnants of it?

It is years since I used AVG and as far as I’m aware they don’t have an uninstall tool.

You could check your registry looking for AVG of Grisoft in the keys, value or data.
Try this first - Remove AVG, see http://www.pchell.com/virus/uninstallavg.shtml

Run this utility to remove all traces of Kaspersky from the registry:

ICE is a US distributor for Kaspersky.

I already uninstalled AVG from Add/Remove Programs.
And I still have the problem.
You said something about registries, keys, values and data.
How do I do to check them?

I would first run the Kaspersky utility I gave the link for, then reboot and see if that is what the problem was.

i did this and I still have the problem
what should I do next?

Windows Start, Run, type msconfig and click OK, now use the Edit, Find function to try and see what might be left, you are searching for AVG or Grisoft.

I deleted all the stuff with grisoft, but i have some problems with AVG
sometimes, it says : Unable to delete all specified values or Cannot delete (name of the key): Error while deleting key.
What do I do?

You need to take ownership of the key, right click on it and select, Permissions, from the pop-up you will see a number of user Names or user Groups. Highlight your user name and in the Permissions for Administrators (you obviously have to be logged on as a user with admin rights) and give yourself Full Control, that will allow for the removal of that key.

ok, thanks, that was the problem
now it worked
thank you a lot :smiley:

You’re welcome.

Are you no longer getting the AAVM/RPC error ?

no, no longer
why?
should I?

The question was basically to confirm avast is now working as it should be.

I wasn’t sure if your comment “now it worked” only meant you were able to delete the key, or if it meant that having deleted the keys you also didn’t get the error messages any more.

No you shouldn’t get error messages if avast is working correctly, that is why I asked.

oh, ok
well, thank you a lot for your help
i really appreciate it :slight_smile:

No problem, glad I could help.
