    Lol all the windows 8 machines have this built in now and that Still come into the shop every day with tonnes of viruses on them. The people who hack windows are so far ahead of microsoft that it makes them look like a joke. MS should consider making a new OS based on unix/linux to get their security problems under control once and for all. Apple is a group of complete ret&rds and yet they were smart enough to figure this out over a decade ago. Google decided to build a new OS from scratch and guess what kernel they used, oh ya Linux. Wake the hell up Microsoft you morons.

    Poor detection and removal. Slows your computer down far too much as it scans every program you open
