Being a proud owner (well that's the way every Mac PC user thinks) of an Apple Mac computer, you always have been under this impression that your machine being the piece of next-generation technical excellence would never be plagued by any harmful threats, better known as virus, spyware, or so called malware that affect Windows-based PCs. True, as Macs are based on Unix, they are lesser vulnerable to any harmful Trojan or virus attack than Windows-based PCs. However, this truth seems to have lasted until sometime in the recent past when cyber criminals began to train their guns on Mac PCs. Nowadays, it more seems like cyber criminals have taken oath not to leave Mac PCs without infectionYou can't do anything about these criminals but you can of course take preventive steps to save your machine from them in addition to saving time and money (you very well know both are very precious).Common Symptoms of Spyware Infection:Is it really a Spyware?Most of the times, what you suspect as a spyware is not a spyware but the cookies or temporary files that got into your PC while browsing the internet or downloading music/videos from various websites. These cookies are usually harmless until downloaded from a purposefully designed, genuine-looking website that a user thinks is safe to browse and download from. Music sharing is also one among other ways to have your Mac exposed to virus attacks.A spyware is usually hidden in email attachment that appears friendly to you; once click opened, it starts installing itself on your PC and unloading other malicious programs that convert your PC into a server to exchange information with the client's system. This way, a spyware takes control of your PC, steals data, changes settings, or corrupts the hard drive without your intention and knowledge.How to determine there is a Spyware?Mac computers usually have very good firewall protection that automatically blocks and removes most of the threats. However, if it is somehow has been compromised (you might not know that it has been compromised until some sort of unusual thing happens to your PC), then you should download a spyware-checking program that should detect spyware or any other harmful threat lying in your PC.You can also run free MacScan demo from you click on 'free download', you will be redirected to download the trial version (which is free of course with two buying options of $29.99 and $49.99).
