I installed it this morning on a e8400 dual core 4gb ddr2 win7-64bit machine and it slowed me to a crawl.It literally takes a min to open firefox,30 secs to open a simple text file now! Will I run into any trouble if I uninstall? I ran s&d and it found nothing I also ran malwarebytes and it found nothing.I'd like to uninstall and install an older version,but dont want anything to screw up.
