Hey everyone, This thread has been written to ask for some advice regarding the infection of my PC by the worm SVL 1.X. So what I've seen, it appeared harmless at first. But the moment I tried to de-install Skype, it activated, adding the feature Windows Collaboration to Program Files. I tried to remove it, but that was impossible, because access was denied. The only group with full permission was TrustedInstaller. The worm has also opened a backdoor in my firewall. I have now turned the feature itself off (Collaboration) , disabled most of the services that it depends on (because they were still running!) , and blocked most of the inbound connections. My question is now: are these measures enough? And is there a way to remove Windows Collaboration and the file sharing services altogether?
