Hi,

I have been using AVG free anti-virus software for months on my new 3XS system without any problems.

However, after a recent upgrade of it to the 2014 version one of my USB devices - associated with part of a card reader reported a problem. This problem continued after numerous reboots - but late last night all it recovered, but then the Bluetooth device on the motherboard then indicated that it had now failed!

I thought this was very strange that the card reader had recovered, but another device had failed - so I did some research and found that AVG (in the past) had caused both USB and Bluetooth devices to appear to fail!

So I removed AVG free and replaced it with another anti-virus product and since everything has been back to normal!

I have put this post on the forum, just in case anyone else encounters the same problems that I did, so however unlikely it seems installed software can cause hardware devices to appear to fail.
