We recently received a donated computer for veterans to use. It's a Sony all-in-one, runs well. We suspect that there is a virus on it. When ever we try to use IE or Chrome there are certificate warnings for most websites that prevent it from being viewed. For example we tried to download Malware-bytes and it prevents us from downloading it.
We tired running Combofix, but after booting OS8 into safe mode, we get an error that the program does not support the OS. However, I believe that for some odd reason, it thinks we are running Windows 2000. Anyone have a work around or any suggestions? Thanks!
