What does antivirus not protect against
So while antivirus alone can protect you from malware, it can't prevent other forms of online crime like identity theft, phishing attacks designed to steal personal information, or attacks on your accounts, to name a few of the many other types of threats out there.
Is antivirus 100% safe
No Antivirus Is 100 Percent Foolproof
Although antivirus is an essential part of digital security, it is not foolproof. Each day, more than 350,000 new malware programs are created,1 and it's very possible for newly created malware to get around protections.
Can viruses bypass the antivirus True False
Many viruses also include evasion or obfuscation capabilities designed to bypass modern antivirus and antimalware software and other security defenses.

Mydoom. Mydoom is arguably the worst malware in history, causing more than $38 billion worth of damages in 2004. Like Sobig, it was another type of mass mailing computer worm that stole email addresses from infected computers and sent itself to those addresses.
What kills a computer virus
The easiest way to remove viruses is by using an antivirus program designed to clean your system safely. If a virus is already on your computer, however, you may need to run this program under very specific conditions.
