Hope you can help. I’ve had a few issues with Avast over the last few days - first, a red circle appeared and I’m told I have an RPC error. I follow the instructions, uninstall & install without issue and now the icon in the system tray is greyed out. It still claims I have an RPC error, but the program takes me to the screen giving advice for a red circle appearing on top of the icon.
Thanks for coming back so quickly. In answer to your questions:
Windows XP and yes.
Using Avast 4.8 - tried to update VPS and was told it was up to date, although under about Avast!.. it says Cannot obtain information, no more data is available.
I still bet that some antivirus could have been installed by the manufacturer of the computer (OEM)…
RPC error is generally due to other antivirus remains and a red cross appears in the top of the icon.
I suggest an installation from the scratch:
Uninstall avast from Control Panel first.
Boot.
Download the latest version of Avast Uninstall and use it for complete uninstallation.
