Hi wussery,
to Safer Networking Forums.
You can download Spybot 1.6.2 from
here. Moreover, please download the latest updates (=detection udpates) from
here.
You can save both files onto an USB-stick and copy it onto your son's computer (desktop). Now double click on Spybot 1.6.2 and install it. I've you have done it, double click on "spybotsd_includes.exe" and all detection updates will be installed automatically.
Open Spybot and run a scan. Does it find something? If yes, tell us what Spybot find. Therefore, right click on the white background after Spybot has finished its scan and save a report from this scan.
You can add these logfile with your next reply.
Does your son have installed an software firewall onto his computer?
Please answer and tell us what you did or what you want to do. Moreover, we can give you further instructions, like opening your own thread in the Malware Removal Forum, where an expert will have a look onto this computer.
