I am sure this is a virus because it is happening to more than one of our computers. It just keeps building up schtasks.exe in the task manager until the machine freezes. I cannot find anything on the Internet that can tell me what would cause it. I have run Bitdefender scans, AntiMalware scans and it finds or fixes nothing. Rebooting and it starts up after bootup. It beeps the computer every time also. I am not sure where to look for an answer. Just looking for someone to point me in the right direction.
