I don’t want to argue which one is better. For me, AVG Free is trustworthy, and it does detect viruses better than another free AV — AntiVir PersonalEdition Classic. For Nod32, well, it is not free, and keeping it in ‘free’ mode for a long period requires a lot of extra work. Kaspersky’s invincible key file is annoying, and so is Nod32’s usename/password mechanism. Yes, you can find the ‘free’ Kaspersky keys, or subscribe to a daily feed of Nod32’s login information or use a trial time stopper. But why do that when you have AVG free which does a very respectable job in virus-detection?
Right now I am using a AMD Tbird 1300 MHz CPU and 512MB memory, a configuration which makes the responsiveness of the system my main concern. I noticed an older version of AVG Free used more system resources than it should, so I decided to give ESS (ESET Smart Security) a try yesterday. But it blocked my Internet connection even after I completely disabled its firewall. It was kicked out of my system within an hour.
Reminiscing of the good old Nod32 version 2.7, I am thinking giving Nod32 antivirus 3.0 a try again. But the question is: is the already famous Nod32 uses less resource than AVG Free? If the answer is yes, it is certainly a big plus for me to make the switch. If not, I will stay with the latest version of AVG Free, which I have the obnoxious link scanner disabled. Both are good antivirus software, and both are well-know for its very small system footprint (AVG uses less than 30MB of memory). The question is, which one is even more efficient?
Can’t tell you the result now, but if you know the answer, please give your informed opinion. When I get the time to test and compare both programs, I will post the result here. So far, it seems AVG Free will stay. I am lazy and I don’t want to employ the tricks to make Nod32 free.
Update: Nod32 3.0 does use less resources compared to AVG Free 8.0 in my recent user experience. But AVG is free and powerful, so it is up to you to decide which one to use.
