Stinger is a quick scan tool for your PC that can detect and remove a specific set of viruses and trojans. If you have reason to think you’re infected, you can download Stinger for free and use it anytime. It won’t conflict with your full-time antivirus, and it won’t try to sell you anything.
There are a variety of free one-time scan tools available, that will check your system for baddies. I’ve previously blogged about ADWCleaner and Norton Power Eraser, and use them frequently to clean my customers’ computers.
Stinger used to be owned by and branded with the McAfee name, but after a series of mergers and acquistions, that has been dropped. Now it seems to be owned by Trellix. And before you wonder: No, Trellix has no connection to Xfinity, despite the logo resemblance.
