There are lots of infected files on the network. The worm that causes the problem with LW opening all the time is pretty common...so you really do have to be careful with what you download:wink:

Make sure that you're using a good AV (antivirus) program & keep it updated!!
Scan a file that you've downloaded with your AV before you open it.

Files with the extensions .exe, .zip & .rar are ones to be especially careful with. I don't download those at all. But, if you do decide to download these, make sure to scan before opening. Check the thread below, it has useful info
