A hard to detect computer virus being referred to as the April Fool’s virus is on the loose and infecting computers today. The virus is actually a variation of a virus already out in circulation, but has had some alterations done to it to make it a little harder to screen for. Many anti-virus programs are not updated enough to know what to look for when it comes time to block this new virus. Make sure your anti-virus software is as up to date as possible.
