My mother's Windows XP system recently got infected with the SHeur trojan (SHeur4.ese). I was able to download and install Malwarebytes Anti-Malware in line with the advice here, but the modem was bringing up odd errors and thereafter was unable to go online. This makes things extra tricky, as I was helping from overseas via Logmein, and Malwarebytes can't update itself.
Still, Malwarebytes claims to have removed the infection, but I suspect that the modem may also be infected, and will reinfect the PC when it is plugged back in.
How do we disable Windows XP autoplay or otherwise prevent infection when she plugs it in, so that she can scan it?
Any other advice would also be welcome.
