Hi Susan, probably no consolation now but I think the shop may have been a bit off with their findings, the blaster worm & variants do what you said (Reboot) but you can clean it from the system without the need for formatting, there are a lot of others that do the same sort of thing, but there are also some that destroy the boot sector of the HDD if it was one of those I suspect it you would not have been able to boot into windows at all (But I'm no expert).
Maybe we ought to start a thread in the PC-help advice with all the tips and tricks for removal of these damn things, we can all have the nessasary firewall AV software in place but with the click of the mouse on the wrong file and it's .
I did a Google just now and found the following ...., but then you would need the fixblast download on disc to finish the job. also you have to turn off system restore.
Terminating the virus Program
To stop your windows XP machine rebooting
1. Select Start -> Run
2. type shutdown -a in the box and press Ok.
3. This will stop the reboot at least for a few useful minutes while you disinfect.
This procedure terminates the running virus process from memory.
(1)Open Windows Task Manager and click the Processes tab.
(2)In the list of running programs, locate the process:
MSBLAST.EXE
(3)Select the process, then press the End Process button.
(4)To check if the process has been terminated, close Task Manager, and then open it again.
(5)If the process is still running then continue anyway
(6)Close Task Manager.
Removing Autostart Entries from the Registry
(1)Removing autostart entries from the registry prevents the malware from executing during startup.
(2)Open Registry Editor. To do this, click Start>Run, type Regedit, then press Enter.
In the left panel, double-click the following:
HKEY_LOCAL_MACHINE>Software>Microsoft>Windows>CurrentVersion>Run
(3)In the right panel, locate and delete the entry: "windows auto update" = MSBLAST.EXE
(4)Close Registry Editor.
