Ask Slashdot: Light-Footprint Antivirus For Windows XP?
New submitter Bauermlb writes "I service computers for retired folks in my community, often older machines with modest speed (2 GHz Centron) and modest memory (512 MB). Adding AVAST to one of these machines slows it to a crawl. Any recommendations for a light-duty antivirus program with a low overhead? (These people do not tend to surf 'dirty' sites.)"
That's what they tell you, eh?

Ad networks/common popular websites have been compromised repeatedly in the past and will be compromised repeatedly in the future. All sites could be considered "dirty sites".
There is no such thing as a safe website. These days any site can wind up hosting malware via banner ads that inject code.
AVG is relatively lightweight but I would suggest you test it and others on some of your target hardware.
I've seen way better performance with it than with McAfee, Avast, etc.
Detection benchmarks typically put it on par with the other free solutions, though it changes from month to month.
Do they *really* need Windows? Or would a lightweight distro with a windows-like interface do the job? Just asking :)
Seems a reasonable bet... http://www.pcpro.co.uk/reviews/software/379933/avira-free-antivirus-13
I've been using it for the last 3 years on XP and now 7, very lightweight. No virus or adware problem (for now). From time to time I also scan my computer with adaware and spybot.

Not that I'm promoting it as effective virus protection, but MSE has a light effect on my Windows partition. Seldom using Windows, but I surf on it ocassionally. Don't know if MS will continue to support it after XP dies, but looking at my parents computer and the 4 websites they visit, I really wonder how robust an anti-virus program someone who is elderly actually needs. Good experiment for somebody: use XP with NO virus protection for a month, visit the same websites these people visit, use a modern web browser (not IE 8), and see at the end of that period if you are actually infected.
It's not so much a memory issue as it is the nature of the beast. Active scanning hogs hard disk performance. I would ask these people if they might want to get a Chromebook or similar. The aging hardware might soon go to PC heaven so they will need to replace the system anyway.

Microsoft is killing updates for XP in a little under 9 months. Get them onto linux or a new PC or it may not matter how good of an antivirus you put on there after that.
Personally I'd rather have my idiots at home glued to the TV than out doing idiotic things
Yes, I know... it failed certification. But often what is used in certification is proof-of-concept or old and very rare samples that may not be "in the wild". It deliberately doesn't detect them to have a lighter footprint and be easier on resources. I use it on 1 GHz machines with 512MB of RAM with no noticeable slowdown. It doesn't miss the stuff that you're actually going to be at risk of getting infected with, in my experience.
You didn't state the OS you were asking about, but IIRC Avast is Windows-only. MSE may fit your requirements.

Sempron, Celeron?
And if you have only 512 MB of RAM, you don't have an older machine-- you have an OLD machine!

In my experience it is so much easier to avoid the whole problem of Windows malware, simply by installing Linux. I tell my friends that I don't do Windows. They then assume I use a Mac - I use a Mac too, so that isn't wrong. When I tell them that I can install something on their computer that will make it work almost exactly the same as a Mac, then they actually get interested and once they have Linux with XFCE running, they never look back.

"I want an elephant the size of a mouse, please"
Antivirus software sniffs the butt of ever filesystem write operation, as well as sniffing the but of every executable image load, as well as every browser plugin load; it also scans the contents of inbound network data, since it could have a known payload using an unknown zero day in the program requesting the data from the Internet.
Most of the code could be made significantly less overhead, but we are talking reducing it from elephant sized to water buffalo sized, rather than reducing it to mouse size. For example, if instead of checking the whole file when every write occurs, it could prevent the file being opened again until a scan-on-close occurred. Both Outlook and IE would hate that, and any browser that didn't operate "stage then interpret" would still have to be byte-stream interposed. As another example, it could decide to not react to every FS event; MacOS has this capability, since it integrates a mandator access controls (MAC) capability, but many OSs do not. And even on MacOS, most AV vendors don't take advantage of this, since it messes with their ability to use the same event streaming model as on their other platforms.
So: no such animal exists, if you want it to also be effective.
ClamWin is "light footprint" because it's no footprint. It has no on-access scanning, which for most people is indistinguishable from not having antivirus installed.

I think he is getting confused and meant to type Centrino which was, at sometime a marketing/branding term for an Intel Reference Design consisting of Chipset, CPU and Wifi. Either way, they wrote it wrong, but lurkers from the past would have recognized it. It was posted on a lot of laptop stickers in the same way Pentium 4, Core X, etc are.

As for /. letting this through... things have changed, have you been gone for the past 3 years?
Not true. Firefox + fireclam addon. Thunderbird + clamdrib (tho you have to work to find it)
That's not on-access, that's on-access-through-a-specific-application.
