For those of you that don't know what Virtumonde is, it's a trojan. Furthermore, it's a complete bastard to remove once it's really started to kick in. Some of its adverse effects are its changing of some important registry items (including adding VIRUS ALERT! to the system time, disabling multiple select on the desktop, changing your desktop background to an advertisement for a fake antivirus and screensaver into the same, disabling the ability to change these items BACK, then disabling the Registry editor so you can't fix anything). It also stops access to websites such as Google and social networking sites (generally high-traffic websites), arses about with all your settings, then puts a load of randomly named DLLs into System32, one of which attaches itself to winlogon so it cannot be removed the conventional way.

Anyway, not so long ago, I got this trojan. It kind of confused me at first, as all it did was stopped me from accessing Google through Fx. A friend told me he had this problem and it was an effect of Vundo (another name for Virtumonde). I went through this website for guidance on its removal. I thought it had gone… until a day later it came back… worse. It then did everything I described in the first paragraph. It took me two days, eight websites, four freeware Virtumonde removal tools and a couple of frustrated headdesks to finally get rid of it for good.

If you ever suspect you might have Virtumonde, get Spybot Search & Destroy to detect it. If you have it, use the links on Vundo's Wikipedia page to help get rid of it. Trust me, you want to get rid of it.
