    So recently, I've been experiencing problems on my Macbook Pro.

    I got it in early July 2014, and I didn't have any problems with it until not too long ago.

    Sometimes, when I'm typing, it will lag, and then whatever I was typing will appear after about 3 seconds of lagging.

    I ran a full scan on Avast!, and it did not detect any infections, however, it was unable to scan 157 files, but it successfully scanned nearly 650,000 files.

    On Friday, I accidentally downloaded the browser hijacker "Installmac," when I thought I was downloading Skype. I then downloaded Avast!, and then I used it to delete the brower hijacker's files. There is none left.

    I've tried restarting, but it has not solved the problem.

    What is the problem? What should I do?

    ----------

    Adding on, the screen freezes/lags as well! As stated before, it is only for 3 seconds, but I would rather have it not freeze/lag at all.

    Uninstall Avast for a start. Then run something like Onyx.

    Really? Avast! could be the problem?

    No offense, I kind of disagree with you. From all the reviews and recommendations it has, it seems decent, and because of that, I doubt it is the problem.

    Any form of antivirus on OS X slows a Mac down. OS X has its own antivirus definitions which are remotely updated by Apple automatically.

    So uninstall Avast.

    Alright. I only downloaded it because I accidentally downloaded that browser hijacker "InstallMac" (Long story, don't ask), and I wanted to make sure all the files from it were gone.

    Is there any specific way to delete it, or do I just drag the program and any related to it straight into the trash on my Mac?

    Alright, I just deleted avast!

    After deleting it, things have been running smoothly! Thanks guys!
