Best Lightweight Anti Virus

Looking for a lightweight anti virus.. Also does running a anti virus kill battery life?

 

Avira free is my pick. Also, whenever anyone talks about what's a good anti-virus, they always take into account the resource usage. In other words, you should check out the other favorite anti-virus threads.

 

Another vote for Avira. No, I haven't found that using a light AV degrades battery life.

 

AVIRA ANTIVIR PERSONAL 9! FTW!
The most powerful free AVs with lightest resources currently.

Avast! 4.8 Home Edition is slightly heavy resources.
I heard that Avast! 5 Home Edition is going to lower it resources.

 

I am using AVG 8.5 and it feels very light and secure. If you disable it or uninstall it you will something like 20-60 increase in 3Dmark06 score which is nothing and also it will not affect your SuperPi score at all (CPU benchmark tool)

 

And the latest virus update for AVG tells you that your iTunes is infected! No thanks. When it comes to anti-virus I prefer NOD32. Incredibly small footprint, not a resource hog, and is constantly ranked in the top 5 antivirus applications.

 

While NOD32 is great, it isn't free. Avira is pretty good and it's free, so it gets my vote.

 

I do agreed with you. AVG 8.5 was totally a *()*&^%$#$%^&*&^% for me.
However, AVG did accompany me for years until last few months, I switched over Avira and found it is WAY better than AVG.
NOD32 is strong and light resources but it is not FREE.

We should cast a vote for BEST FREE AV in this topic.
And BEST PAID AV too.

 

avira. tried so many, and i'm sticking with this one.

 

Had the OP asked for free, lightweight antivirus applications, I wouldn't have recommended NOD32.

 

The lightest antivirus if you are asking is NOD32 FTW

 

my vote to NOD32

 

Norton Antivirus 2009. A complete redesign over older Norton products, NAV09 is extremely light on system resources (on my test system, it used fewer resources than NOD32) and yet has great detection rates.

It's not free, but certain stores (Fry's Electronics in particular) frequently have rebate deals for NAV that make a 3-license copy $0.00.

 

I am having this problem? Is this AVG related? I started a thread about the itunes latest update warning about this, but if this is an error in AVG it is a full different story...(175 viruses detected thanks to AVG)

 

I currently use NIS 2009 which is a significant improvement from previous Symantec AV offerings. It's very light on CPU usage and even provides a monitoring feature with conumption bars and charts showing how much of your system it is using. My levels are usually 2-6% on idle computer use.

However, I have to admit that the most lightweight anti-virus currently in the market is Eset Nod32 as it only has a footpring of ~34MB. If you don't need a firewall and have another program to suffice for it, go with Nod32 for lightest usage.

 

I recently changed to Avira, decided that AVG was not working correctly (plus my itunes loss is something I wont forgive). Up until now it has been working very good. It seems to consume less than AVG.

Yesterday I was playing The Sims 2 will performing a full scan, and it ran ok (considering my laptop is single-cored). Lets see how it goes.

 

AVG users always would see a huge impact of difference by switching to Avira or Avast!. I am AVG users for years as well and I switched to Avira a few months ago. Avira is still considered as No.1 FREE AV currently with its freaking awesome protection and light resources.

 

I think Avira was best but it would not update on Vista 64-bit so now I'm using AVG.

 

Be careful with the *()*&^% as some mods consider that as bypassing the filter and will dock you points. Heck, I had just straight asterisks and got docked so I can't imagine what they will do to do you with all those fancy characters. Watch out.

 

My vote is for Avira. Never had any trouble with it, never actually notice it running. The free version is great, expect for those darn nag screens after updates (yes I know there is a way to bypass it). I may actually consider buying the full version in the future.

 

nis2009... i use it myself

 

I also use NIS 2009 and it is a big improvement over previous Symantec AV versions in terms of CPU Usage. Best feature is that it also comes with a CPU Usage monitor how much of your system Norton is using up.

However, I also recommend Eset Nod32 as it will have a really light footprint on you computer of only approx. 34MB.

By the way, I do full scans for External HDs running on battery and Norton Internet Security doesn't seem to drain or prolong battery life any more than any other program you're running.
