    Check Activity Monitor.app (in /Applications/Utilities/) to see what's using up your resources.

    Could you give a better description of what is slow, opening files... ect?

    If so hard drive could be faulty / damaged :)

    Am I cruel if I write YES?

    No, you don't have a virus. There are not viruses for Mac OS X. Wait for GGJstudios reply, as that explains it in more detail

    Have you taken a look at the Activity Monitor in Applications / Utilities?
    Don't forget to select to SHOW ALL PROCESSES and sort by CPU.

    Also what Mac and what Mac OS X are you running and during what task does the MBP feel slow?

    Temporarily create a new user and see if this solves your problem.

    You're are absolutely wrong.

    From another thread:


    The above is the post GGJstudios alludes to in the following post I quoted (from this thread), which might be of interest to people who believe in viruses on Mac OS X.

    I'm fairly new to Mac, so I could be wrong I am not stating I'm 100% correct but when I see this, it looks like a virus to me? :rolleyes:

    I am aware that some Antivirus companies do scam, and play on the "fear" on new computer users *Cough* Norton.

    Epic Fail...
    Another thing you can do is to take your installation DVD that came with your Mac, put it in your Mac, and reboot and hold the "D" key. This will run some diagnostic tests on your hardware, so if you have a hard driver that is failing, this would tell you that.

    I'm sure that Apple has addressed this issue with the numerous security updates and 2 new versions of OS X since that article was released.

    You are new to computers as well?

    Inqtana is a proof-of-concept worm. from the website you linked to.

    A worm is not the same as a virus. Read my second post again (which I didn't write but stole).

    Things to check for when your computer is "running really, really slow":

    Open Activity Monitor or, in Terminal, type "top". See if a process is using close to 100% of CPU time (or more, on dual-core machines). Sometimes, for some reason, on my system Finder starts to eat CPU time. Force Quitting Finder or restarting fixes the problem.

    Unexplained freezes and long delays in reading files or writing could be a sign of impending hard drive failure. Given the OP's post, I think this is highly suspect. If you suspect this, STOP USING YOUR HARD DRIVE immediately. Get it replaced with another one, then put the old one in a USB enclosure so you can make a backup of your files (if not already too late).

    Check to see if there is network activity going on. Is Finder trying to scan your LAN for connected servers? Trying to access a shared drive on the network? That can cause long delays.

    It's okay. I'm sorry if I came off as rude though.

    So, enough derailing, the OP might not get back otherwise.

    Have you done any of the things you were advised to do and inform us about?

    Someone on a Mac thinks they have a virus???? Wow! That's a first!!! :D Here's a sure way to find out.... if you have technology (or even mainstream) news reporters beating down your door, wanting an interview, you know you have a Mac OS X virus. Be sure to look for a few Microsoft representatives in the group!

    Nobody is saying that Mac's can't, or won't ever, get a virus. If anyone does, they are wrong. The Mac is not a magic infallible platform. One day, someone, somewhere, will discover a vulnerability, and exploit it, and we'll have our first Mac OS X virus.

    We're just saying that so far, in 10 years of OS X, this hasn't happened yet.

    There are worms and trojans, but these will always exist since they play on social exploits rather than computer exploits. Heck, the original Trojan Horse didn't even have anything to do with computers. :) Right now, there aren't very many of these either for OS X, but they do exist. How does one currently get infected with an OS X worm? (1) Surf shady sites looking for porn or warez, (2) download an app from an unknown source, (3) open it, (4) give it your admin password. As long as you can avoid doing all of those steps, you'll be fine.

    It's alive!

    This thread has gained a life of its own. The OP hasn't responded... maybe he was scared of the flamers.

    Solution: Keep threads OT! :D

    Who's flaming? The OP asked about viruses. The responses have been about viruses. What do you think is flaming or off-topic? Some people don't respond for a while because they have LIVES.

    Nope.

    What about any of the other ideas that have been thrown at you? Care to comment on them? Just because you don't know what is slowing down your computer, doesn't mean it has to be a non-existent virus. We showed you some ways to fix and find out what could be wrong.

    Btw, have you read the thread at all? We told you there are NO (0 = 1-1 or 0 = 27382719 - 27382719) viruses for Mac OS X.

    Well, theoretically you can certainly get infected with a virus on a Mac. As of yet this hasn't happened in reality. A subtle but very important nuance!

    Anyway, slow computers are mostly caused by other things like hanging applications, crashing hard drives, etc.
