How to Schedule an Automatic Scan in Avast Antivirus 2015 for Free; How to Disable (Stop, Turn Off) Avast DeepScreen 2015 for Free. Didn’t I pay you for it? Aren’t you protecting my computer? Arne Mathiesen February 24, 2018 Reply. When I run an Avast Boot Time Scan, it shows many corrupted program files; but when I run sfc/scannow. Avast Free Antivirus, boot-time scan running In case Avast detects an infected system file that is critical for running Windows or is located in Windows folder or its subfolder, it stops and waits for an action to perform.
I installed Avast Mac Security and its sister VPN app. I ran a scan and found lots of adware and dumped them. I accepted it default settings and went back to work. However, while I was able to search topics using Google, I couldn't open any webpage links. So I decided to uninstall Avast. Bis mistake 1..I dumped the app to Trash (didn't use the uninstall process). Went back to work, couldn't get any internet to work, no email nothing.
I found it had left extensions in the preferences in each of the browsers (safari, firefox and chrome). I removed these and email worked. But most web pages still cannot be opened.
I am assuming Avast has left me with a little gift for uninstalling it incorrectly. Does anyone know how to get rid of it completely? Files hidden in Library or Active Monitor or what the file names might be? Any help would be appreciated.
BTW - I rang Avast for support. They told me they could fix it, but that I have to pay them $179 for technical support. Nice customer service.. Avast 2017 gratuit.

If your computer is infected with malware, running an antivirus within Windows may not be enough to remove it. If your computer has a rootkit, the malware may be able to hide itself from your antivirus software.
This is where bootable antivirus solutions come in. They can clean malware from outside the infected Windows system, so the malware won’t be running and interfering with the clean-up process.
The Problem With Cleaning Up Malware From Within Windows

Standard antivirus software runs within Windows. If your computer is infected with malware, the antivirus software will have to do battle with the malware. Antivirus software will try to stop the malware and remove it, while the malware will attempt to defend itself and shut down the antivirus. For really nasty malware, your antivirus software may not be able to fully remove it from within Windows.
Rootkits, a type of malware that hides itself, can be even trickier. A rootkit could load at boot time before other Windows components and prevent Windows from seeing it, hide its processes from the task manager, and even trick antivirus applications into believing that the rootkit isn’t running.
The problem here is that the malware and antivirus are both running on the computer at the same time. The antivirus is attempting to fight the malware on its home turf — the malware can put up a fight.

Antivirus boot discs deal with this by approaching the malware from outside Windows. Boot your computer from a CD or USB drive containing the antivirus and it loads a specialized operating system from the disc. Even if your Windows installation is completely infected with malware, the special operating system won’t have any malware running within it.
This means the antivirus program can work on the Windows installation from outside. The malware won’t be running while the antivirus tries to remove it, so the antivirus can methodically locate and remove the harmful software without it interfering.
Any rootkits won’t be able to set up the tricks they use at Windows boot time to hide themselves from the rest of the operating system. The antivirus will be able to see the rootkits and remove them.
These tools are often referred to as “rescue disks.” They’re meant to be used when you need to rescue a hopelessly infected system.
Bootable Antivirus Options
As with any type of antivirus software, you have quite a few options. Many antivirus companies offer bootable antivirus systems based on their antivirus software. These tools are generally free, even when they’re offered by companies that specialized in paid antivirus solutions. Here are a few good options:
These are just a handful of options. If you prefer another antivirus for some reason — Comodo, Norton, Avira, ESET, or almost any other antivirus product — you’ll probably find that it offers its own system rescue disk.
How to Use an Antivirus Boot Disc
Using an antivirus boot disc or USB drive is actually pretty simple. You’ll just need to find the antivirus boot disc you want to use and burn it to disc or install it on a USB drive. You can do this part on any computer, so you can create antivirus boot media on a clean computer and then take it to an infected computer. Avast for mac high sierra.

Insert the boot media into the infected computer and then reboot. The computer should boot from the removable media and load the secure antivirus environment. (If it doesn’t, you may need to change the boot order in your BIOS or UEFI firmware.) You can then follow the instructions on your screen to scan your Windows system for malware and remove it. No malware will be running in the background while you do this.
Antivirus boot discs are useful because they allow you to detect and clean malware infections from outside an infected operating system. If the operating system is severely infected, it may not be possible to remove — or even detect — all the malware from within it.
