|Here's another good reason to have a third party firewall (Re #2 above). Mine detected something trying to make changes which proved to be a trojan. This allowed me to pinpoint the exact time from prefetch files, so it was a great help in getting it sorted.|
Although support has just stopped I use the "PC Tools Firewall". Not one of the cleverest but it has now proved its worth in a rather unexpected way. Fortunately the need to update firewalls is fairly low so I shall stick with it.
Always pop back and let us know the outcome - thanks
