Clean up viruses from an infected computer by disconnecting from the Internet, starting in Safe Mode, deleting temporary files and then running a virus removal program. These steps are typically enough to remove common viruses.
Disconnecting from the Internet is the first step to take when a computer becomes infected with a virus. This can prevent the virus from spreading further or transmitting personal information online. After disconnecting from the Internet, turn off the computer and restart it in Safe Mode by pressing the F8 key repeatedly as it boots up. This brings up the Advanced Boot Options menu, which contains the Safe Mode option.
After the computer boots up in Safe Mode, the next step is to delete temporary files. This can speed up virus scanning and may even remove parts of the infection. Users can delete temporary files by typing “Disk Cleanup” into the Start Menu Search Bar or going to the Start Menu and selecting All Programs, Accessories, System Tools and then clicking on the Disk Cleanup application.
After deleting temporary files, users can attempt to remove the infection using an anti-malware program such as Malwarebytes or Kaspersky Virus Removal Tool. These programs can scan for virus infections that conventional virus protection software often misses. They also offer simple virus removal wizards that walk users through the steps of scanning their systems and removing any infected files found.
