Many thanks for the suggestions – her PC seems to be fine now, thanks to your assistance.

We will proceed with your additional suggestions (Delfix & Unchecky, which I think will be particularly helpful for her) over the next few days. Malwarebytes is already taken care of – she’s now purchased the premium version, which has allowed me to schedule a daily scan for her at a time when the computer will be on but she won’t be using it. Thanks for the Java info – I did notice that she’s got more than one version installed. She must have Java for her work, and once she’s verified that the proprietary program required doesn’t need an older version, I’ll be sure to follow through on that.

Again, I greatly appreciate you helping me help her – I couldn’t have done it without you!
