I have been used this norton antivirus.This antivirus is worst for PC.The main problem of this antivirus is that it space more than 2 gb in pc. There are always updates in 2 days.It does not detect viruses of pendrives. It infects the computer process.PC gets slow day by day due to this antivirus.The technical support is also bad.They did not give quick replies.
Sometimes the key is not working of the antivirus
