There is currently a massive increase in complaints from Skype users in relation to viruses. The newest and the one that seems to be infecting a lot of users at the moment is one that sends a message to the users with the text:
lol is this your new profile pic?
The users are asked to then click a link and are taken to a downloadable .ZIP file which will infect your computer.
Skype advise that all users update their Skype application and make sure they have up to date anti virus running at all times. More importantly, we advise users to be cautious. When you see links from friends, always be careful and check that they are genuine.
