All the antivirus software’s are the same they all scan and delete Viruses, Trojans, and Worms etc. The important thing is knowing how to scan a pc! Viruses mostly uses startup programs to infect a computer therefore before performing full computer scan using any antivirus user should make sure that he/she logged in using safe mode. While in a safe mode user has to start the antivirus software manually then perform full scan. Safe mode kills all the unnecessary programs and allows only drivers any programs which need to run the OS as a result while scanning for viruses in safe mode your antivirus will normally scan more files and has more access to any programs loaded to your HDD.
Kaspersky is still most reliable antivirus software.
