Summary: this is my 4th kaspersky product and i have to say that i now have blind faith in kaspersky.the scan time takes a bit if ram is low but it protects from every threat out there!advanced disinfection process to save the pc from crashing after executing a file was most useful for me,as i usually don't scan pen drives while inserting them into my pc.cool user interface makes it much better.so don't think just go for it!
