System restarts automatically whenever a virus detection alert is coming on the screen.? My office desktop is been installed with Avira Anti-Virus software. Whenever the modem is switched on a virus detection dialog box appears on the screen. But when performing the action to be taken for the virus detection,the system RESTARTS immediately.I just cannot close the virus detection window without taking any action for the virus found. I also scanned the whole system and deleted the viruses present. Even then when the modem is switched on virus start coming. Please Help.
