I bought a brand new laptop from Bestbuy 2 months ago that came with 60 days free Norton and BB gave me a Kapersky disc for free. Norton expired so I removed it and installed Kapersky. Bam, instantly my new laptop slowed down to a crawl. I will be removing it and installing something else after reading all of the comments regarding Kapersky. It's a piece of crap, probrably works great, but I'd rather not be annoyed and frustrated every minute I'm using my computer!
