Perhaps it hasn't troubled you, but one day a software called EasyBits Go installed itself on my computer. "Ding ding ding" - malware alarm!
Turns out it's a gaming plug-in for Skype (as in an extension for Skype). Lucky me, otherwise a full reinstall would be in order.
I did uninstall it, although I don't know if that worked. I've read posts saying the uninstaller had issues, leaving the software in some kind of limbo-state (unaccessible but not uninstalled). According to the same post, it was installed by a patch error.
Good to know. I'll be locking down my computer soon, making sure not to accept any UAC requests in the future! Bloody bugs...
