File Sharing stuffed up

Tech-Archive recommends: Fix windows errors by optimizing your registry

2 xp pro machines using simple file sharing.
Dlink router/adsl/wireless modem
Multiple users all administrators and No passwords used.

This has been working fine for ages, sharing a couple of folders on
each machine.
All of a sudden I am geeting unable to connect to this machine, you
dont have permission, Cant find machine, etc, Enter password, etc.. I
can still play network games so it looks like just the file sharing
part is breaking down ?

Last things that happened.
Installed and removed Crashday (this added securom service which I
disabled)
My friend connected with his xp pro laptop using Lan cable and copied
files successfully
Copped a trojan vires, with U.exe in root of C drive

Thanks for you help
John B
