Avast Antivirus
The core of any antivirus software is the way it does in virus detection and removal, which differs from provider to provider. Avast is very high in this department and has an efficient detection engine found in the top first antivirus software solutions. In the tests, Avast was able to detect and remove several malicious and antivirus files. I recommend increasing the sensitivity to full when using Avast, since it improves the detection of "unknown" viruses.
