AV wise ... (not counting NOD32 .. .which ISN'T free .. just FYI) .... I would go with Avira or Avast ... AVG gets lower rankings consistently ....Avast and Avira go back and forth for the #1 free AV ... I have both installed in different machines I have and they both work great
----------------------------------------------------------------------------
These are a few tips to help secure your computer at least somewhat ... .I am not saying non of these programs do
not have false-alarms or you'll be 100% protected all the time.. These are just a few tips
Anti-viruses -
There are many different review sites and many different opinions... I recently saw in the current PCWorld Magazine a rating of free antiviruses ... I have to say I think its pretty accurate ... Not sure if they rated AVG... but if it was (the ratings were 1 to 5 ... best to worst) than AVG would be #6 (in other-wards, not even on the list)
1) Avast - ( http://www.avast.com/free-antivirus-download ) I have to say on my 8year old laptop it was really sluggish but on my @ 1 and 1/2 year old Toshiba with Windows7, it is a-ok .... Very Good Detection Too
2) Avira - ( http://www.avira.com/en/avira-free-antivirus ) This is what I have on my old laptop and what I had (Trying Avast on my new Toshiba ATM) on my new PC before trying Avast.... I love Avira and even if I am using Avast ... I still recommend Avira 100% ... Detection only slightly behind Avast ... they deducted "points" for the fact they like Avast's Interface better
3) MS SE - I have to say I don't trust MS, but I have to given in and say all the reviews are very positive .. I don't like how it forces you to have windows updates on "download and install automatically" .. or right out of the "box"/"gate"/whatever .. I had to install 60MB of updates ON top of the I think it was 12MB for the Anti-virus itself ... but for newbies that really don't like Avast, or Avira for whatever reason ... It's a decent choice.. with the exception of one test that rated 50% detection and Avira rated 70%, MS SE is on par with Avira Detection wise .... Did MS finally get something right?... If they slim down there database and let you change the Windows Update settings when MS SE is install... I'd say 100% yes
Those are all Free, but if you feel the need to want to pay for one (for whatever reason), try Eset NOD32 ... its the only non-free antivirus I recommend and it didn't even lag my older systems
Firewall -
I would recommend Comodo's Firewall 100% and also if you do not like Comodo for whatever reason, Outpost makes a great firewall product and they have a free or pro version available. Both of them (Comodo or Outpost)are easy to use and configure
Malware/Spyware related -
The only two products I would recommend are both freeware and the best at what they do. MalwareBytes ( http://www.malwarebytes.org/ ) -(a must have in my opinion), and SuperAntispyware ( http://www.superantispyware.com/)
maybe the only other addition would be Spyware Blaster
Honestly, the other scanners are not worth it.... even the freeware scanners are not really worth it if you ask me.
