well ive tested just about every single anti virus internet sercuity suite there is and kaspsersky really surprised me with the sercuity level being as high as it is and yet so user friendly and so little false alarm it truly was amazing it doesnt hit the ram as hard as other but does require a bit more cpu when ur doing something never hogs only takes what it needs then when it dont need it no more its yours again. <br/> <br/>the program was very stable never crashed even on vista ultimate x64 witch just about every single anti virus and internet sercuity suite crash's on it just didnt crash. when u turned off a feature like the firewall it really was off unlike others u can turn everything off and they still run in the background witch is bad if they block something and not tell you. kaspersky ask's if it should be allowed to access the net or moddify the registry. <br/> <br/>another nice feature that i have not seen on any anti viruses/sercuirty suites is it knows when a file has been modified since u last ran it and it will ask if its ok and if u want to block it. firewall is defently the most user friednly firewall i have seen when its in training mode. the detection rate for virsuses/spyware that start up was truly amazing caught it in 1 second and asked what to do with it. <br/> <br/>BAD: there was very few bad things with this but still nothing is perfect <br/> <br/>Firewall: can be a bit annoying when in training mode and asking for everything to have access but u genrally have to go through that but atleast it asked unlikes others just block unless u open it and allow it in rules <br/> <br/>Anti Virus: generates a bit more false alarm's than another anti virus/sercuirty suite(nod32 smart sercuity) but not as many as others <br/> <br/>Kaspersky console: there is only 1 issue that i found was that when u click file anti virus u expect to see the scan that is running but u dont but it tells u at the main of the console so truly no issue but still <br/> <br/>Compatiblity: absoulty no compatiblity issues what so ever support all of the major os's of todays world with eaz <br/> <br/>OVERALL: <br/>kaspersky left a very little foot print on my performance but has a really good protection with very little false alarms never takes what it dont need in resources and extremly user friendly and works on all major OS's of todays world overall great protection

Hi, have been using kaspersky for a couple off months now and find it to be more than satisfactory and more affordable, regular updates and no virus intrusions to date. I feel it has freed up my computer and runs quicker than when i had Norton installed. although i am not a computer whiz the program is in my opinion, is tops
