Tip of the week: How to defeat nefarious PC files

Search them out; Reinstall; Remain vigilant

Search them out. Run a full security scan with your software and delete files that could pose a threat. Make sure your computer is set up to perform regularly scheduled scans and to automatically download security updates.

Reinstall. When all else fails, “reinstall your system from scratch.” If it comes down to this, be sure to back up your files to a USB hard disk and fully reinstall your operating system. Then copy the files back and reinstall applications.
