What is the best free antivirus software around? The only one I can think of is Microsoft Security Essentials, but I'd like to hear more about other free ones.

Avira , AVG, Avast just to a name a few
Personally i use Avira, no complaint from me.

+1 for avira, used on all my machines and stable

That's one of em....avast, avira, avg all does good work....for good detection rate, avira does well..avg and avast does detection and removal well

There are many free antivirus around. You can try using Avast free edition as well as it is quite light. If you feel the overall protection is not good, you can install Comodo Firewall on top of your antivirus as Comodo can give a solid protection. They were free after all.

I use MSE for all my machine. Why? Coz its free
AVG, Avast or Avira will expired in one year time(free edition), dunno can renew license after that or not~

avast, panda, avira

Vote for comodo internet security. Better then antivirus alone. BTW there is no best av only highest detection rate. Most important is free hehe

U can renew license after 1 year for Avira and Avast, AVG?? MSE detection rate is low, however it do not use lot resources..

avast, avg, avira , microsoft security essential

Avast Free(More like a security suite without the firewall) and Panda Cloud

I would recommend Avast, been using it for about 4-5 years now.

avast user too. You should really try version 6.

i would prefer Comodo Internet Security. If antivirus alone,Comodo also got. + its free.

avast or avira..both quiet ok for free product..

AVIRA no doubt.... have been using nod32,avast,avg,karspersky but stays as avira user for years

IMO avast is the best. never fail me before(just make sure you update the database)

i remember using avast free version b4
its kinda annoying when it suddenly detect a virus
it made alarm like sound with a nuclear radiation logo

I use MSE atm.

Used to use AVG/Avira/Avast.

Avast was just...weird.
AVG was overrated then and started to feel unreliable.
Avira....I feel they have a good shield/real-time protection system but their virus cleaning system suck balls. <-- Caught a few diff type of virus/worms [ofc not the ordinary ones] and it couldn't get rid of it.

I feel MSE is alright.

Avast definitely. Just remember to turn off the sound once installed- to get rid of those alarm sounds
