I got norton antivirus with my new laptop. It's 60 day trial period is over and to be very frankl i am not at all happy with tthe antivirus. It makes my computer start at snail's pace. I have done a bit of research on the internet as to which antivirus will be best for vista home premium that could be downloaded from the internet. i am totally confused which AV should i download. As far as my research goes, a lot of people are satisfied with AVG and avast. If any1 can help me out. I was about to download kaspersky internet security( 1 month free trial) but someone over here suggested it slows down the performance. I havent got good reviews about mcaffe and norton, ofcourse my personal experience tells me that norton is utter crap.
