There is a rogue program, named Error Check System making the rounds of Facebook Members-- non-Facebook members Facebook members may get an error message in the notifications section that reads "(Friend's name) has faced some errors when checking your profile View The Errors Message." This program 'invents' an error, instructing the user to click on a link to fix it. The error may show you have no programs or it may indicate your computer is locked. Neither of these "errors" are true. "The warnings are fake and a viral attempt to spread the application and recruit more Facebook users" according to Graham Cluley, a senior technology consultant with Sophos. Do NOT take any action to 'fix' the 'error'. If you are a Facebook member, do this: However, non-Facebook members are at risk as well. A Web search of "Error Check System" will yield a link to a site that contains code that will initiate a fake virus scan and try to fool users into installing malware disguised as antivirus software, Sophos identified the malware as Sus/FakeAV-A and Troj/FakeAV-LL. I have seen the 'missing programs' log and the 'locked out' message log. Both were false and could be fixed but put the users in a high state of panic! What is most important is that you do not act on these fake error messages or click on any script to 'fix' the problem!
