Invalid Security Certificate – Solution to the Problem

Invalid Security Certificate is a warning which prevents you from accessing the internet (browser, skype, msn, etc) since the internet security detects a breach of security. The first thing one should do when this things happens, is to check his time, date and timezone. If these are not properly the internet security will not allow you to access the internet. You can change the time/date settings by right clicking the time and date usually situated on the bottom right of your computer task bar.
