THanks everyone for your concern and advice.
Am currently making a backup of my data on to my external HD- there shouldn't be any .exes in there but I know I will need to:
- scan this drive before retransfering the files
- refrain from connectng this drive to any othe system until I know its safe.
I'm currently having a look at the AVG disc but even that is way beyond what I am comfortable with technically.
I didn't realise these things could be so ingenious. My system can appear to be clean for a while. THen I reboot and the two iexplore.exes come back.
Lawrie does anyone in your team do Sunday house calls to Paris?
