Interesting, I just read an Internet Security report that I get monthly citing Social Networking Groups and Facebook in particular as prime targets for hackers.
Facebook boasts over 175M members and where are the cyber nare-do-wells gonna find a better 'feeding ground' than that?
All they need is to get one (out of 175M) unsuspecting member to open their email and they can then propagate their viruses, trojans and worms through that member's address book where it spreads .
The report went on to say that this is where the majority of the newer virilent viruses have been traced to. The ones which invade your root files and are therefore immune to any AV software you may be running. These can also self-replicate and mutate. In most cases, the only fix is to wipe your HDD.
So as much as I love you guys, I'm taking a pass on Facebook.
BTW, if you do any online purchasing or banking, then a major concern to you should be the danger of someone invading your system and keylogging it. Keylogging is where they can uncover your keystrokes and from these recover your logins, passwords, CC #s and such.
Trend Micro has a nifty little free program to foil these guys. It's called Transaction Guard. Basically, you download a virtual keyboard and type your sensitive data to it with a mouse. Then you go to your banking site, vendor or even an ISP and cut & paste the info to the site from the virtual keyboard. This way, there are no keystrokes for a hacker to log. While it is a bit more cumbersome than using your keyboard, it does offer absolute protection from keylogging. See it here:
