Choosing a free antivirus

Hey People!:

I would like your advice about antivirus, antispyware and other ...

I wonder what the antivirus (if possible) which shall recommend for its best performance in terms of protecting the system.

Also if you can recommend some antispyware, antimalware, and so on. (as far as possible with free and real-time protection), we remain alert to possible attacks.

It is known that none to protect 100% of the "Virus," but a good combination can be effective in the face of threats (at least against the most powerful ...)

We thank you very much!

greetings!

Well ...

The most recommended in the forum to remove the infections are:
SUPERAntiSpyware Free
Ad-Aware 2008 Free

And as a virus, I personally, I like the kaspersky, but it is not free as you want (like almost none) so if you want a free only know the avast ... But the Panda and NOD-32 are very good ...

Sincerely ...

I think the AVIRA also can help you. And its personal version is free.

A combo that has serverd me VERY well and all can be downloaded for free:
AVG7.5.
Super anti-spyware
PC Tools Threatfire free (works as compliment to AVG)
Windows Defender
Spyware blaster
and for manual weekly scans....Malwarebytes

all free downloads and have worked well for a while now

Only AV not make your system 100% safe as most of AV works after your system get infected. So better combine AV with firewall.

Use Comodo internet security (AV+firewall) free to use unlimited updates.
