After testing, there are several types of anti-virus software that can completely remove malicious files:

AntiVirus & AntiSpyware
AntiVirus & AntiSpyware, its original "deep removal technology" is very powerful. It can go beyond the operating system restrictions and directly operate the data on the hard disk. It is a nemesis of stubborn malicious files.
When using other antivirus software, we often encounter the following problems:
• The software clearly prompts that the malicious files have been deleted, but after restarting the system, the malicious files are still found.
• Although the system enters the "safe mode", the malicious files cannot be deleted, and the system prompts "cannot delete the running files".
Why is this happening?
This is because the malicious file uses some special technology, and after taking the highest control of the system, it does the following three things:
1. Prevent any third-party program from taking the highest control of the system.
2. Prevent any third-party program from ending the malicious program so that the malicious program is always running.
3. Prevents any third-party programs from deleting files of malicious programs.
After malicious programs do these things, many anti-virus software can neither end its programs nor delete its files. This is why many anti-virus software cannot completely remove malicious files.
However, because AntiVirus & AntiSpyware's "deep removal technology" can overcome the limitations of the operating system and use the original machine code instructions and a series of complex methods to communicate with the hardware to obtain hardware control, AntiVirus & AntiSpyware can directly erase the malicious files on the hard disk. We are using this "deep removal technique" to delete malicious files.
This is well-known old antivirus software, with very large user group and good reputation. The only drawback is that it is expensive, and the price has always been about 20% more expensive than other similar vendors.  Click here to enter the AntiVirus & AntiSpyware product page.

ESET NOD32
ESET NOD32, this anti-virus software is known for defending against unknown viruses. It works by establishing a virtual operating environment internally, putting some unknown suspicious files into this virtual environment, and then recording the file operation. If there are malicious acts such as stealing personal data and damaging the system, suspicious files will be classified as malicious files.
You don't need to worry about the real operating system being affected because the suspicious files are running in a virtual environment and will not have any impact on the real machine.
This anti-virus software has outstanding advantages and disadvantages.
The disadvantage is that the created virtual environment needs to occupy a part of the system memory. If your memory has about 4G, you don't need to worry about this problem.
The advantage is that any unknown new virus and various variant viruses will be intercepted by it and cannot invade your computer. At present, there are only a few antivirus vendors with this technology. It is the best one!
If your Internet environment is very complicated and it is often invaded by various new viruses, this antivirus software is recommended.  Click here to enter the ESET NOD32 product page.
