Google-chrome – After virus, Chrome & Internet Explorer won’t connect to the internet, but Firefox works fine

For Google Chrome:

Wrench Icon (on top right) -> Options -> "Under the Hood" Tab -> "Change Proxy Settings" -> "LAN Settings" -> Make sure that the "Automatically detect settings" is enabled and the "Use a proxy server for your LAN" is disabled.

This should work for IE also.

Looking at the source file for Chromium's image resize and filtering, it appears the filter used for upscaling images is a radius 3 Lanczos filter. (see function ResizeMethodToAlgorithmMethod, I guess the default choice is used as the comments seem to fit better to downscaling). The convolution kernel is defined in the function EvalLanczos at the very top of the file, and has no provisions for any modification after compile-time.

Unless I read the code very wrongly (see the constructor for ResizeFilter), the filter(and the scaling) is applied one dimensionally in one direction at the time. The screenshots sort of seem to indicate that the IE filtering is two dimensional, and weighted by radius rather than maximum hor/vert distance. (This might be a false lead, though.)

I guess you could somehow determine what sort of filtering IE does and reimplement it, either just replacing the Lanczos filter, or (more fancily) update the rest of the source to call your filter. The latter would be necessary if you can't work around the one-dimension-at-the-time issue. I would not recommend it, though, unless you have particularly strong feelings about how your browser upscales images.

PS: The scaling in Opera also seems to match your Chrome screenshot.
