I did some research: You are running 3 antivirus programs on your machine which is causing your problems.
360 (Translation): "Security guards with killing Trojans, clean plug-in, fix bugs, computers and other physical features, and created a "Trojan firewall" function, relying on cloud detection and identification of the first to be comprehensive, intelligently blocking all kinds of Trojans, to protect users account, privacy and other important information. Currently trojan virus has far exceeded the threat of a large, 360 security guards cloud security technology used in the interception and the effect of killing Trojans, speed and outstanding performance on the professional, can effectively prevent personal data and privacy by stealing Trojan, known as " Trojan's first choice to prevent. " 360 security guards themselves are very lightweight, and also have the power to accelerate, optimize garbage collection and other system functions, can greatly accelerate the speed of the computer, containing the 360 software also helps users to easily download butler, upgrade, and uninstall various software applications strongly."
Plus you also have a Kaspersky product installed with this boxed 360 version, but I do not know what it is.
Either way, it is a security software with an antivirus that is conflicting with Avast.
You need to make a decision to either keep Avast or keep 360, because you cannot run more than 1 antivirus software on your machine at the same time or there will be problems like you are having now (other programs not running, antivirus not running correctly, getting false positives, machine not running correctly, etc.).
So you need to decide what you want to do. If you decide to uninstall 360, you need to do it the way the vendor (the boxed version) tells you how to do it. Then reboot your machine.
Then you should Repair Avast:
- Go to Control Panel > Add/Remove programs > Avast Antivirus.
- Scroll down and choose Repair function in the pop-up window.
- Reboot.
If the Avast Repair does not fix things, we will then tell you how to uninstall and do a clean install of Avast. But I first want to hear what you decision will be as I do not want to overwhelm you with instructions. Thank you.
