I fear I’ve just down­loaded a Tro­jan…

Mac Format - - TO THE RESCUE -

Tro­jan horses that af­fect OS X are rare, but they do ex­ist. Most, like the Flash­back Tro­jan from 2012 (which mas­quer­aded as an in­staller for Adobe Flash), work by en­tic­ing users to down­load a file. An­other Tro­jan hit ear­lier this year, called OSX/ CoinThief; it posed as a tool to al­low Bit­coin users to send and re­ceive anony­mous pay­ments. In­stead, it in­fected sys­tems and stole Bit­coins from wal­lets.

To avoid in­ad­ver­tently in­fect­ing your Mac with mal­ware, don’t down­load any­thing un­less you’re ab­so­lutely cer­tain you know what it is. If you’re un­sure, do a Google search as to whether there’s any cur­rent OS X mal­ware out there.

If you sus­pect you’ve down­loaded some­thing nasty, run Soft­ware Up­date. Ap­ple of­ten is­sues patches that (in the case of Flash­back) re­move the mal­ware.

If that doesn’t work, down­load a free anti-virus tool (such as Avast!). You can then use it to scan your hard drive for known mal­ware and, if any is found, re­move it. Avast! can also alert you when you click on a link that it thinks is un­safe. It dis­plays a green tick next to re­sults that it deems safe. By in­stalling it you give your­self the best pos­si­ble chance of avoid­ing down­load­ing mal­ware or vis­it­ing web­sites that host it.
