How to Remove Internet Viruses or Worms

Internet viruses and worms can wreck havoc on a computer system. The effects of an Internet virus can range from small (e.g. some viruses simply monitor Web usage) to devastating (e.g. erasing or corrupting critical system software components). More often than not, an Internet virus or worm will cripple a computer and make it unusable to the owner. Learn how to remove an Internet virus or worm to safeguard your computer and protect your important data. Also, learn how to avoid viruses and worms in the first place. When it comes to such computer problems, prevention is crucial.

Instructions

1. Step 1

   Avoid downloading or opening files from strangers or untrusted, third-party websites. When it comes to Internet viruses or worms, prevention is key. Most viruses and worms infect a computer when the user unknowingly opens a program or file downloaded from an untrusted website. If a friend emails you a file that looks suspicious, ask him about its contents before opening the file.

2. Step 2

   Backup your important data regularly. Use an external hard drive or blank CDs or DVDs to make copies of important files, documents, photos and emails. Having a backup of your computer data is important when a virus infects your computer system and corrupts or deletes your files.

3. Step 3

   Download and install an antivirus program to remove any viruses or worms currently infecting your computer. If you do not have an antivirus program on your computer, download a free program such as AVG Free antivirus scanning software (link in the Resources section).

4. Step 4

   Scan your entire computer system for viruses and worms using the antivirus program installed in Step 3. Depending on the size of your hard drive this process may take several hours. Select a complete, thorough scan of all system data. Some viruses or worms hide in system files.

5. Step 5

   Remove and delete any viruses or worms found by the antivirus program. This process is automated once you give the program permission to delete the file. The antivirus program will give you an option to attempt to clean the file before deleting it. Always try to clean the infected file before erasing it. Deleting an infected or corrupted file should always be the last resort.

6. Step 6

   Scan your computer regularly after the initial virus scan and removal process. Regular antivirus scans will help protect your computer from future infections.
