can you clarify for us that the Birch DSL does
NOT have an anitvirus protection method/package within it?
if it does NOT then I suggest you go ahead with the AVG download ; A method I used on another , what was then a dial up pc, to get the avg exe on IT was to 'cheat' a bit !!
IF you have another 'working' computer that has a CD writer on it(?)that you know to be 'clean' and uninfected, you COULD burn the avg exe on it IT then insert that cd into the bad computer and install the EXE that way ?
save the exe to a loaction where you can readily find it
may I ask what the computer was doing when the computer guy took the Norton off ?
please go to tools/internet options/delete cookies/delete files and press on both tabs to clear out ALL your temporary internet files
please try to take on and run the
SMALL but powerful tool of

http://download.nai.com/products/mcafee-avert/stinger.exewhen I ran THIS on a BADLY infected computer I found a good option was to drastically reduced the size of the temporary internet files folder to virtually NIL ; you may wish to do the same
do you have the Windows original CD with licence key available?
see how you get on with those tools?
