My grandpa has an old laptop that's really sluggish, taking over 30 seconds just to open Chrome. He uses it daily and has downloaded various files in the past, so I'm concerned there might be some malware on it. I've run the basic Windows check and checked the Task Manager, but I couldn't find anything unusual. I'm not very tech-savvy but I can follow instructions. I was thinking about downloading antivirus software but I'm not sure which ones are safe or effective, plus I'd prefer not to spend money if possible. What steps should I take? Should I try antivirus first, or is there something else I should do instead?

First things first, back up all his important files. You can’t go wrong with that! After that, it’s good to know the exact manufacturer and model of the laptop. Now, regarding malware, Windows Defender is actually pretty solid for most users. Many third-party antiviruses are unnecessary and can just annoy you with subscription prompts. Slow performance might be due to the old specs—if he has less than 8GB of RAM and a hard drive instead of an SSD, that’s likely the issue. Upgrading to an SSD can make a huge difference, and doing a clean install of Windows could help a lot, especially if the laptop can handle Windows 11.
It's probably not malware if Windows Defender is running—that's effective against most threats. The bottleneck is likely the laptop's specs. If it has low RAM (like under 8GB), it won't handle modern browsers well. The CPU speed is another factor. Basically, it might just be time to accept that the older hardware is struggling with current demands.

Very true! If it has an HDD, especially a 5400RPM one, that’s adding to the slowdown. Switching to an SSD would make a world of difference.
