Can a computer become virus infected and the installed anti-virus program not detect it and if so how can this virus be removed?

Answer

Yes, that's possible. First of all, there is no single antivirus-program, i know of, that will eliminate every virus that has ever been made. Secondly, antivirus-programs are always step behind virusses. That's because there first have to be a virus, before you can develop a method to eliminate it ….. This development is always hours (or even days or weeks) behind ….

However, the change of having a unknown virus is virtually non-existing. If a virus becomes known, there will be a solution for it in (almost) every antivirus-program!

If you think, however, that you have a virus and your antivirus-program can't find anything wrong, then do a additional online virusscan (f.e. with the online virusscanner of Trend Micro: housecall.trendmicro. If you're still declared healthy, but you're still suspisious, surf to one of the many antivirus-forums that are excisting all around the world ….. Or place your question here, at FaqFarm ……. Like you did ;-)) :-))

Good luck, Jahewi :-)
