Now a days, which Anti virus is best ?
I used Avira in my laptop. You can't determine which is the best. It depends on the file has been infected by the virus. Some software antivirus detecting virus but other software antivirus were not. It is not ok to have more than one antivirus installed. Having multiple antiviruses installed would cause first, they will fight over viruses because having multiple antivirus programs then they will detect viruses even is not threatening your program, secondly is they will kill each other because antivirus program would compete with other antivirus programs that are monitoring and sending information about your system and tendency to look viruses, so it will attempt to block it and remove it., and lastly, they will sap on your power if you have more than one antivirus it will operate simultaneously, your system’s effectiveness can be greatly diminished or completely wiped out altogether and performing redundant operations.
