Has your computer been hijacked?

[capt-zero]

All of this is very interesting. It was a seemingly rather umbiquitous virus that led me to adopt linux as my main OS. After installing Kubuntu, one of my first actions was to install ClamTK and run a recursive scan. It found 52 infected files and quarantined them. I later deleted them. Since then, I've found nothing. Of course, I don't surf in Windows anymore. The virus I caught that sent me to linux, I caught from going to only three well known and fairly respected sites, after having my machine's HDD's professionally cleaned (consisted of having the HDD's wiped followed by a new Windows installation). After having this done and getting my computer home, I logged into my then homepage: Google, then checked my hotmail account (without opening any email), and then to craigslist and boom I was infected again. I forget the name of it, I believe it was a rootkit, PNS?rootkit. At any rate it was scrambling any jpeg file I accessed.
Now I know any machine can be hacked, no matter what the OS. Even running linux we should be concerned with malware. So I suppose my question is; can our machine's Windows installation catch malware through our linux browsing? Would a Clamtk scan block the infection? I know this question exposes me as the rank amatuer I am, but I'm not the only one browsing this site, so the answer may be important to some.

For the curious... more on the FBI's takedown of the Alureon/DNSchanger botnet.

My assumption was that the malware infected Windows machines only.

I posted it because several folks on the forum also run Windows in dual boot or by virtual guest, and may not be aware that their Windows machine may be compromised. I should have been more clear.

Alureon is a rootkit, so an unprotected Windows VM is potentially vulnerable. Zlob modifies IE browser helper objects, so I suppose it could infect a Wine installation -- I don't know enough about how Wine works to offer any certainty here, though.

Which, I'm assuming (there I go, assuming), applies only to Windows PC's, or maybe, Wine on Linux?

[SteveRiley]

That checker is looking for evidence of specific pieces of Windows malware... Alureon and Zlob.

[Snowhog]

Specifically for Windows and Mac's? Don't see anything on the site that specifies, or even identifies, Linux machines.
