I have a computer owned by the family of a friend that is complaining about a large number of unwanted programs being installed on the computer. The family stated that some of those programs began opening pop-ups advertising various things, e.g. virus scans. One member of the family went through the control panel and manually removed several of the programs. Subsequently Ccleaner, McAfee, and MBAM scans have been run, each identifying varying PUPs and being instructed to remove them. According to the family most of the PUPs appear to be gone, however there does seem to be a small number (1 to a small handful) that reappear upon reboot.
The computer is running Windows 7 Home Premium 64-bit. At this point I am looking for advice on tools or techniques to verify the issue is confined to PUPs and there hasn't been a malware infection, and to identify any remaining PUPs and remove them.
I do not have regular access to the machine in question, however the friend does and will be able to run any scans, pull information, etc. as needed.
