Hi,

if he has confidential/patient data on his PC, he should DEFINITELY reinstall from scratch !!! and CHANGE ALL PASSWORDS…

because his PC is insecure/not safe !!!
Sasser brings a backdoor, and it even has an exploit itself which allows hackers to gain FULL CONTROL over the machine…!

to be able to backup the data & settings, he could:

  • disconnect from network
  • clean out Sasser & co. with avast’s Cleaner (OFFLINE)
  • enable XP’s built-in firewall (OFFLINE)
    optional then:
  • go online, update windows, download/install AV/avast, Firewall etc etc… :wink:
    Afterwards:
  • backup and then format & reinstall according to “VirusRemoval” below
    :wink:
