Trying to install Avast Home edition on an Acer Aspire One netbook. The computer is already infested and shut down all attempted installs of Avast and MalwareBytes. I can get WinClamAV to install, but it does not locate/remove the problem. Nor does AdAware, which is installed, locate/remove the infested files. I need to be able to do a boot scan, but can’t get anything past what I think is a root kit. Any ideas?
OK, I got a handle on this. Between SaferNetworking’s RegAlyzer and MalwareBytes’ FileAssassin, I was able to remove some startup processes and files that seemed to be holding things back. Got Avast to install and doing an update, then run a boot scan. What a pain in the butt this has been.
Let us know how you get on with it.
Hi…
I can imagine. 
I would encourage you to perform the following along with what you have already done. First, see post #4 by Tech at this thread…

In addition, I suggest an online scan be performed…

Hope this helps.
