It's 1st of April today - the April Fools day. In the good old days, we used to have lots of viruses activate on this date, showing various messages or playing pranks with the users.
Unfortunately we live in different times now. We haven't seen viruses like this for some time, as the #1 profile of a virus writer has changed from a hobbyist to a professional.
We don't expect to see any funny new viruses today. We expect to see the usual batch of bots, trojan downloaders, keyloggers, spam proxies and email worms.
