That would still put it in the top 2 here…. I am running bit defender. Latest 1. I guess it improve a lot since this test. I also know that this is top AV in terms of catching the bug.
Not as low as avira, but I will take extra safety any day. Try Webroots new Secure Anywhere suite. Its so light you have to experience it yourself. That is not enough,it has to block all malware too,and it does. Look it up,its great. I suspect it is far less than webroots. I found this one is very good with cloud scan, light weight and also free.
Love to hear from you Raymond. I used to recommend AVG earlier but since Avg used to take a long time to delete viruses after scanning so i thought of changing my antivirus and gave Avast a try since then i got no problem good features and UI and fast too i recommend every friend of mine for Avast. I was using AVG but have trouble upgrading then switched to Avast.
My Lenovo laptop has a feature that tells me how many seconds it takes to boot. With AVG installed the time always creeps up to about 50 sec. With Avast, the time is around 30 sec plus. Have to add that this boot time is not entirely accurate as it takes longer than that until I can actually use the computer. We used Kaspersky in our office a few years back and even with the background protection service turned down to its least aggressive settings, it would often bring the hard drive to its knees slowing down all applications in general.
I never had any issue with them. Most of the time using too many AV will not detect any virus. It just slowing down your system dude. Too high for my taste and I removed Avast. Looking for a really light solution…. The only one which works perfect for me is nod32 smart security. May be at initial stages these will work good but try to check the same after some months of installation. Please review Kingsoft Cloud Antivirus. I have been having fantastic results with it. Baidu bought Kingsoft.
How does this even matter when computers have 4Gb plus RAM and barely use at a time? It would matter when resources are scarce and I doubt if that is the case for most users, at least in developed countries. Only in the last 3 or 4 years have most off the shelf computers come with that amount of memory. Before that, it was mostly 2GB or 1GB. Granted, they don't represent the majority of the worlds users but they do show a trend, LOTS of people don't have anywhere near 4GB of RAM, "developed country" or not.
And for them, this article might be useful. I bet at least half have 1GB or less, and half of those MB or less. Virtually no features or options? I just switched to Bitdefender after using Avira for several years and Avast for a short while they scared me off when they started plastering me with e-mails to renew my license 2 months before it was due, Avira scared me off with their fairly hidden option for auto-renewal of the license that was never presented to me during purchase — they did refund me, though.
Best AV software I have used to date. Have tried many others, but the balance between effectiveness only what I can gather from AV tests and performance is superb. Will stick with this for at least another year license and then probably reevaluate, but just wanted to point out my confusion with your statement. The free BitDefender is completely different to the paid versions and was widely criticized when released because it had virtually no options to configure it at all.
There have been a few things added since the initial release, but the differences between free and paid Bitdefender is still vast.
This is exactly what I was looking for. Much more convenient that testing each of them for myself. I would like to see CPU usage in the next one. Thanks so much, Raymond! Thanks, just what I was looking for. Been a user of avast for years and was surprised that it was the lightest one all along. Hello, i see that avast!
Internet Security and avast! Webroot has always been my 1. Their so-called discount every once in a while is a US-only and b not a real discount. I am currently looking for an av that is light yet effective for my netbook.
I been using panda antivirus but it skips some files that is infected then i used avg it more effective but it clogs my system.
I read comments in this article, no one notice the performance of ESET, I believe it has the best and yet light av base on your experiment. When opening Avast!
The only time I notice a stange memory usage is when stopping a scan for the memory jumps up and down between mb until it idles back under 6mb. It would be very nice if you colud select some rows in Process Explorer like in Excel and show you somewhere the sum of parameters, or sort on selected and show sum bellow maybe you could propose to Mark — author of Process Explorer.
As we all know memory is faster than hard drive. Consuming more memory will surely cause poor performance if the ensuing lack of free memory causes swapping.
Now my machine is swapping like crazy, performance sucks, etc. Killing Firefox causes Norton memory to go back down after a while. But this is the case where the Av using memory will cause poor performance. Thanks for publishing the results but it would have been nice if you sorted the results based on values vs. We use Vipre Ent. I dont go by any data published in websites. I personally tried many free antivirus and I settled with Avira free.
For my system it is the lightest. Avast is definitely a resource hog. With Avira my system boots up in less than 30 seconds. Memory usage is not relevant enough. Apparently you are not working with wide variety of computers, outside the business world. Many ordinary people are using older computers that have good enough CPU processing power, but are bogged down by lack of RAM. Not everyone buys a new computer every few years and that is actually wise.
I agree with you, but again, memory is not the only factor to know if an AV is slowing down the system or not. HDD stays the slowest component of a PC. It would have been nice to go a little deeper in the tests. WebSecure is the lightest, I tried it for months and it has definitely a low impact of performance, however interface is weird.
You can see it using some skydrive upload with word or just running quite a few programs and surfing on the web. The only time that Avast slows down my computer is when first booting up as it checks for updates which is fine. I never have never experienced system lags using ZoneAlarm but I have occasional lags with Avast Free. I had to uninstall Comodo because the system lags got to be too much of a problem to handle.
This applies to all products that use advanced HIPS, even though they may use little memory they still make your system response time much slower. Testing just memory usage will not give accurate results. This can also happen when simply opening a document. Thank you for the article Raymond. I like the Final note which you written. Next time also include Avast internet Security in the test.
These should also be compared on how effective each finds a virus, which when it does, might also increase memory used; and how long an active scan takes. It is more important than memory test if you want to know how av affects your system.
I gave up on Norton and McAfee because they were memory hogs, hard to use and not getting along with software. Thanks for the article, Raymond.
