How to Install Avast Antivirus on a USB Drive

by Randall Blackburn

Though the full version of Avast Antivirus must be installed in a computer, the Avast Virus Cleaner and Removal Tool can be installed on a USB drive. You can then use the USB drive as a portable cleaning tool to run during the startup process. The Avast Cleaner and Removal tool removes viruses and malware, such as rootkits, that load along with the operating system.

1

Open a Web browser and navigate to the Avast Cleaner and Removal Tool download page (link in Resources).

2

Click one of the download links on the right side of the page to download the EXE file.

3

Click the “Save” or “Save As” button to save the EXE file to your hard drive.

4

Insert the USB drive into a free USB port on the computer. The USB drive registers to the operating system as a removable drive.

5

Open the Charms bar and click the "Search" option, and then type "Computer" (without quotes) into the Search input box. Click the "Search" icon. Click the "Computer" link in the search results on the left side of the screen.

6

Click on the “Removable Drive” icon for the USB drive. A window opens to display the contents of the drive.

7

Drag the Avast Cleaner and Removal tool EXE file onto the USB drive window and drop the file into place. The Avast Cleaner and Removal tool is copied to the USB drive.

8

Double-click the EXE file to run the Avast tool from the USB drive. Click the “Start Scanning” button to begin the virus scan.

Warning

  • Though the Avast Virus Cleaner and Removal Tool is available from freeware and shareware download sites, the product has been discontinued by Avast. No support is provided by the company.
