The BEST
Here is my 2 cents
I have been using AVG for 4 years and it works good but Techspot recommends Avira and Avast, in that order, so I tried Avira and a 'SAME DAY TEST' (scanned with AVG, then uninstalled AVG and installed Aviria, and then scanned PC with it. Avira found 1 trojan AVG did not, Aviria is also faster ( 1 hour vs. 3 hours with AVG - large system 3 HDs with total 9 partitions).
However, I know that AVG does a very good job on scanning emails both downloading and uploading. So far I have not seen Aviria scanning email. I also did not think that Aviria was very easy or helpful in setting up 'Custom' scanning profiles.
Techspot also recommends Comodo and ZoneAlarm. I have been using ZoneAlarm for 5 years and Comodo, on a laptop for 2 years. I like ZoneAlarm better, it is easier and has a better custom setup.
As far as AntiSpyware I use them ALL (almost). I have used CounterSPy (liked it very much but $$ not free, also WebRoot - not to impressed it). I was introduced to SuperAntiSpyware, MBAM (Malwarbytes) and like them very much. I also run Spybot S&D and AdAware when I am cleaning up things.
I did Norton's for 15 years but the last 5 years it choked my system so bad it would hardly run. That is when I started using all of these others. I have also tried F-Secure, Micro Trend, etc. I have come to the conclusion FREE works just as good and sometimes better - so I will never waste my $$$ again.
And thanks to TechSpot for all the tips and introducing us to 'Good' "Free" software.
As far as LiveCare, I have never tried IT and since it is Microsoft I "NEVER" will.
