I think my old computer has a virus.

When I was a younger and didn’t know any better I looked up some not-so-age-appropriate sites, and some pop ups showed up immediately — I closed them and ran a bit defender scan immediately. Nothing showed up in the scans. I’m not sure if this caused it or if I accidentally pressed on an ad that triggered it, but every once in a while on google chrome the start screen for a very risqué fantasy game would open in another tab. I deleted my history, ran a scan directly through google chrome, ran my antivirus multiple times, uninstalled chrome and reinstalled, but it still kept showing up every once and a while. That was all it did that I knew of. I didn’t have any compromising information on it since I was too young to frankly, and I haven’t used it in years, but a few years later when my mom suggested donating it during covid I refused to for obvious reasons. I’d like to access some old photos on it and I just need to know if there is any way I might make it worse.
