Some pop-up ads have been appearing. Chrome blocks them, but it's annoying anyway. Some websites (like Google Reader) seems to not work well due to this.
I suspect this is due to a malware in Chrome for a couple of reasons: It is only in Chrome (not in Firefox), and it seems to have been syncronized through my other PC (with some delay).
I know it's pretty unlikely to have a malware or virus in Ubuntu but, I know too that Chrome uses Sandboxing. So... is it possible to have a malware "sheltering" in Chrome? If yes, how can I remove it.
