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.)"

    "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.
