i recommend you Avast, which is better among these antivirus programs, it can give your computer real-time protection and also it has anti-spam filter and a built-in firewall I just use it for some time,it really performs great!
Wrong, the anti-spam and built in firewall are only in the paid for version of avast!. The paid version of Avira includes those features as well.
Personally, I would go with whichever you choose, they both have their Pros and Cons, I used Avira for around 3 years, and just recently switched to avast! 5 while it was still in beta. Here is what I foundConsAvira
: Slow, confusing interface. Updates sometimes don't work, or are extremely slow. Have to babysit it while it scans (it prompts you what to do whenever it finds a virus, yes you can make it automatically quarantine, but that is only AFTER it has found at least 1 virus in the scan)Avast
: Haven't really found many except the scan speed may be just a TINY bit slow, but I am running a very old system.ProsAvira
: The best detection rates of any free AV, but sadly, also one of the highest false positive AVs.Avast
: Very fast updates, high detection rates, medium level of false positives but definition updates solve this problem quickly.
Both programs have great real-time protection, as well as amazing scan and removal methods.
So again I say, its really down to personal preference because avast or Avira isn't going to stop every virus. Avast might detect a threat that Avira doesn't, or vice-versa.
