Hello. I've used avast! as my anti-virus software for the best part of three years, and for the majority of that time I have had no issues. However, over the past couple of days my version seems unable to update from the client itself anymore, automatic updates aren't working... and I cannot force them to happen by going into the program and telling it to update. Though, I can update virus definitions by downloading the separate .exe file from the avast! site and running it.
From what I can tell, it seems to be a permissions problem but I have no idea how to solve it; my account is the only one on my PC, meaning I am the administrator.
The error I receive when I try to update by going into the client is "Last Encountered Error: Access is Denied". By delving into my avast! logs, it comes up with the following:

I first suspected that this might be a form of malware causing this problem, my initial scan with Malwarebytes hasn't came up with anything. To conclude, I am perplexed as to what I need to do to solve this problem, and any help would be much appreciated.
