Most often one does not know that they are infected with Malware until it is indefinitely too late. A few signs can lead you too believe you might be infected, such as incredibly slow PC performance, browser pop-ups when no browser is open, and security warnings from security programs that have never been installed on your computer, can make you feel uneasy about your machine. Try these tools to kick Malware in the butt. 
Update Antivirus
The software IDs within antivirus software identify existing malware based on what has come before and the latest updates available. Make sure your antivirus software is current, with all of the latest installs. Having software that is even one day out of date leaves your machine at risk for encryption. Antivirus vendors offer updates based on viruses they encounter both in the lab and in the field.
Find Safe Mode
Most malware, when designed correctly, is ready to evade System Restore points set in Windows. Perhaps this might be enough to fix the problem, but say that its not, as it most likely won’t be, try running a program designed to kill any known malware process in progress, such as RKill. The other option in this case is to boot Windows in a way that will not allow malware to get started, aka Safe Mode. By first restarting your PC (Windows 8 or 10), hold down the shift key during the boot sequence, and choose Safe Mode within the troubleshooting options.
Delete Hiding Places
You should then delete all temp files that could hide malware. To delete temp files, open the Start menu, type Disk Cleanup into the search bar and it will check the C:drive for all temp files that can be safely deleted. The software IDs within antivirus software identify existing malware based on what has come before and the latest updates available. Make sure your antivirus software is current, with all of the latest installs. Having software that is even one day out of date leaves your machine at risk for encryption. Antivirus vendors offer updates based on viruses they encounter both in the lab and in the field. After this process it is advised that you run an antivirus on-demand scanner, such as Malwarebytes Anti-Malware. This program is a great line of second defense against malware because it often comes to the rescue if your initial antivirus fails.
No Connection
A RAT, means that someone is remotely accessing your PC. Your first step in this case is to get off the internet. Turn off the Wi-Fi, remove the Ethernet cable, turn off the router, whatever needs to be done in order to detach from the internet. Now, being disconnected from the internet ensures that you are no longer able to be controlled, but it makes it a great deal harder to receive the latest antivirus without access to the internet. The latest software will need to be retrieved from a third party PC, at a different location preferably, then transferred to the RAT PC via USB flash drive. Another option would be to reboot the computer with a CD. Running a full anti-malware utility, these CDs are sometimes called “rescue CD” and can be used without internet connection. Of course, in order to use this option, a CD player will be necessary.
Portable Help
If all other options have failed, it may be the Operating System that has already been infected, making it impossible to even download the newest antivirus software. In order avoid the OS and let the antivirus do its job, you will need to utilize portable apps through a USB flash drive. These portable apps do not require a direct installation. Apps like this consist of Microsoft Safety Scanner, CLamWin, McAfee Stinger, or Kaspersky Security Scan. You can also try a mix of many portable apps since they will not conflict as you have to run each scan individually. There are also other software options such as Spybot and Symantec’s Norton Power Eraser that specifically target a type of malware called crimeware, that run scams. Although this is measure is aggressive, and often times deletes files that might not be malware, all in the effort of safety of course.
