How do I get rid of malware?
Recent versions of Windows are likely to have basic free anti-virus software built in or available free from Microsoft. If your anti-virus and anti-spyware software hasn't detected malware, scan your system with the free malware scanning programs listed below. You should scan with all programs because each program detects different malware and make sure that you update each program to get the latest version of their databases before doing a scan.
- Malwarebytes' Anti-Malware Free
- SuperAntispyware Portable Scanner
- Microsoft Safety Scanner
- Anti-Rootkit Utility - TDSSKiller (see this alternate TDSSKiller download page for more information)
- AdwCleaner (see this alternate AdwCleaner download page for more information)
