Hello,
Where do I start? First, I have a Sony Vaio with Vista Home Premium. Ok, when I turned on my computer I received an error message from Avast! that it could not download updates...I was also unable to do it manually, although I had an internet connection. I could not turn on the on-access protection, and I got an RPC error when I tried to run Avast! So, I went to the FAQ and did what they recommended. To no avail. I did this as administrator and with firewall deactivated. I tried to repair Avast and got this message "A setiface error has occurred:2 Try to reinstall or contact support please!" Then, I removed Avast using the removal tool...downloaded and tried to reinstall. I got a message saying that (translated from German) "Avast setup no longer works."
Here's the kicker. No matter which anti-virus/spyware programs I try to install...I get similar messages. I've restored the computer to earlier dates, I've used safe or secure mode. Nothing! I can't use Hi-jack this either. Anybody out there with a clue about what is happening on my laptop?
