macupdate.com-apple.co virus found
It seems that this macupdate.com keepchanging the latter part of their domain and playing about.
When the popup box saying my Mac is infected, Press OK to repair.
I forcequit it. But didn't start holding down shift key for safe mode start.
I experience some abnormalities, during the 6-7 times start up, my volume up and down button did not allow me to adjust the volume whilst watching YouTube, Mac wouldn't shut down, popup box later saying that word is open ( not really) or Safari was still open etc.
Seems like different symptom every time I start again. Sometimes it runs OK.
What sort of problem is this?
Thanks
Mac Pro, OS X Yosemite (10.10.4)
