Yup, Kaspersky are a good name, with a good reputation of being on the ball in terms of analysing threats and releasing new definitions in a snap. Eugene Kaspersky runs a very tight ship by all accounts.
Some people have a problem with them being a Russian company. But I'd say that's pointless politics, and people shouldn't tarnish everyone with the same brush.
(as a side note, F-Secure is multi-engine, and one engine they have embedded is Kaspersky .... although they may have reviewed this of late ).
