Mac isn't as safe as you think.

Recently a Trojan horse has been appearing in copies of iWork 09, the latest edition of the popular Mac productivity suite. OSX.Trojan.iServices.A is considered a serious threat according to Intego, a Mac security software developer. These pirated copies contain a real working iWork 09 but also an extra package called iWorkServices.pkg. This once again reaffirms that Macs are NOT immune to malware.

Once a user starts installing iWork the trojan gets installed in /System/Library/StartupItems/iWorkServices. In the newer versions of Mac OS it will ask for an administrator password but in older versions it won’t. This path normally contains Apple startup items. This gives the the trojan complete read and write access for the root (ie complete control).

hmmm... well nothing is immnue to anything....lol

Yep , Problems are everywhere and I had already mentioned earlier in one of my posts that, people are buying mac becoz mac has not encountered as many issues as windows. The reason is obvious as mac is still young and malicious programmers are going to create malicious programmes for the majority users[windows] and less frequently for the minority users[mac]. Its just question of time that we would get to see more and more malicious programmes affecting mac, just what happened with windows. Nothing is really safe 100% and no anti virus is the best 100% but one has to always take preventive measures. But in case i get any stubborn infection to my pc , I am straight away gonna refer to Malware Department in the forums undoubtedly & get rid of malware asap as we have keen malware experts in the forums.
