Are there any proven sites / emails that give you Bubbles? I want to know so that I can avoid it.

If you know one, do NOT post a link... Just say the general name of it.

If your talking about the "bubbles" from the RS website then I have no idea what they are on about since it's not actually "bubbles" but another trojan that actually steals the info.

Either way:

It was built to infect users through Skype (mainly)..
Just be aware of things that looks like a Skype message pop-up and make sure your antivirus is up-to-date.

The links are usually one's that doesn't make a lot of sense and contain a lot of letters and numbers. Some of the links are webpages from lycos and freewebs although as far as I know they have been taken down.
Other links may appear to be naughty sites.

Just be warned of any dodgy links from your contacts (generally a good practice). Ask the original person if they have sent you a link and what it's about before clicking on it.

PS: If you really want the names of the site (and I mean really) I can tell you them, with part of it removed for the safety of the forumers of course. Although I think I have already gave you a good enough idea of what to avoid.
