Just to be on the safe side i want to know if their is a safe way i can scan my mac for a virus? From my personal experience anti virus's do more harm than good Suggestion? The test may take a few minutes to run, depending on how many files you have and the speed of the computer.
In this article we do a case study on a recent Mac problem, give reasons why you should always start afresh with each new Mac you buy and in a larger sense why virus checking is more important for Mac users than other platforms, even though viruses are a less widespread problem. Mac Viruses Are No Joke We all know the jokes about Mac viruses, but we are staunchly “platform agnostic” around here.
Recently one of our Macs began acting very strangely. It seemed to always be doing something when nothing was running. The first thought was a virus, and while investigation and virus scanning proved this was almost certainly not the case, the fact remained that something was horribly wrong. It turned out in the end a legacy.ktext configuration file was more than likely to blame, running drivers for some now non-existent graphics tablet and scanner from a previous install which ate all of the free memory. We’ll get to the madness of cloning your old machine to a new one in a second because this problem raised a bigger question: the role of Mac users in the world of virus spreading. Catching the Bug For Mac users, viruses are less of a problem than users of other platforms (you know who we are referring to, right?), although they are possible and do actually happen.
It’s a big mistake as a Mac user to ignore this because although viruses which affect the Mac by covert insertion are uncommon, many other threats exist which could paralyze or ruin your current installation. We recently covered, for example. And while unaffected by PC virus threats, you can easily become a carrier for PC virus infections. Windows files cross your desk invisibly all the time, and it’s the right thing to do to scan and remove them before you pass them on, otherwise this could be potentially very bad news for your PC-using co-workers, family or friends. In the recent repair of the Mac we mentioned above, for example, scanning revealed a couple of minor Mac threats but literally hundreds of PC viruses on the system.
That’s alarming as hell. Burn Them With Fire There are a few free options which do very well to remove any Mac or PC threats from your machine. AVG, Avast and Bitdefender are the options we tried in purging this problem Mac.
Bitdefender free version is a scanner and goes through your files detailing any threats, pointing you to the problem files so you can delete them. AVG Free is a scanner and a shield program. You can explicitly scan your machine periodically for Mac and PC threats. The shield part means it stays resident even when you are not actually running the GUI and checks threats as they arise in real time. Avast is similar to AVG in that it is a scanner and a shield, scanning your disk for threats manually but also staying resident to catch anomalies in real time. Like other resident virus checkers it won’t install unless potential threat collecting apps are closed: Like AVG, it gives you the option to scan for threats by presenting a front end GUI: And manual scanning can take considerable time. A full system scan can take hours (note the time taken and percentage covered here in our problem Mac for example): You should do that at least once a month to be sure.
