Major issues with Lion

AMCarter3

Ever since I upgraded to Lion, I've been having serious slow-downs and freezes on my new Macbook Pro. At first, I thought the issues were hardware related, but after 3 weeks of good days and bad days, I finally removed Sophos Antivirus from my computer. Interestingly, I have had no issues since.

    Andrew,

    Since removing Sophos Antivirus from my computer, I have had no issues. I honestly do not know for sure if Sophos was the source the issues. All I know is my laptop is functioning well now without Sophos on it. 

    So, I am struggling with this... I would like to have your antivirus protection on my computer, but obviously not if it conflicts with the OS and causes slow-downs and freezes. I would like to know what steps you take to verify that your software does NOT conflict with OS X and does NOT cause excessive CPU consumption. What is your level of confidence that your Antivirus software does NOT cause issues with OS X?

    Hopefully, someone from the product team can give you a good answer as to the QA processes they go through for the product; I do know that they have a large test rig and proper QA processes set up to track software changes for a significant amount of time prior to releasing a product update.

    I'm on this forum as an end user, not as a representative of the support forums themselves or of the product team.  I use the product myself both at work and at home.  That said, I have a fairly customized OS configuration and have fine tuned my Sophos configuration, so my experience with the product is likely to be significantly different from yours.

    The one area I do have some extra insight into is to the actual malware detection routines.  In the labs we have strict QA procedures on releasing identity updates as well, and do performance tests which, if they fail, will auto-reject any release of the identities.

    On OS X, the most likely place for performance degradation from a detection standpoint is Java applications with many small class files and DMG files that are significantly larger than the files they hold.  We are continually working on ways to optimize current detection methods, and have plans to improve both Java and DMG scanning in these areas.

    That said, the experience you've had with slowdowns and freezes is not something to be ignored, and will not be.
