My client has XP pro, it has been working fine for a few years, the other day he could not print, open files over the network, and his sound stopped working.
After a bunch of time figuring out what was wrong and finally came to realize that a number of services that were set as automatic are not starting at boot. One of these - the workstation service - was preventing the network access.
avast is the antivirus, I've run malwarebytes, combofix, and I got a hijack this log.
Any ideas would be greatly appreciated.
