How often do you scan or computer for viruses and/or other risks?

[Rock_on_2008]

I use a firewall on my PC and the anti-virus scans every email i receive and alerts me with every download.

There is some stuff you should avoid on the net. Keep away from porn that has heaps of viruses, torrent downloads are dodgy as and many viruses are attached within "free" downloads. Downloading music from Lime wire can result in malware or various other viruses.

Chain emails should be avoided like the plague and do not forward those emails on. emails with sussed headings should not be opened. If you do not know the user who send attachments do not open it.
