According to this it may mean more problems for dial-up users. At least that is how I read it. Why because dial-up users will just be adding more bandwidth to their already restrictive amount. The bandwidth add will probably not be that much so the negative impact may be negligible but I don’t see how how avast! using the Cloud for some of its malware checking will improve the performance of dial-up users or anyone for that matter.
OK here we go folks. Some of these are downloadable desktop applications and some are “Cloud-based” (applications that run on the Web). Whether you choose to download and install the downloadable ones or use the online office applications, one thing is for sure: If you have a dial-up connection, you’re at a disadvantage. Web-based (in the cloud) your connection may be too slow to use applications in The Cloud (on the web) and the file sizes for office suites run between 140 and 200 MB – formidable downloads for dialup users, like days and days of downloading.
I think they will do on the cloud some verification (behavior, heuristic). It’s not the same as running a full cloud application. Apples and oranges…
Also, as everything else on avast, probably you can disable the feature if you’re on dial-up.
