Unexplained Activity on My Laptop: A Cause for Concern?

I find myself puzzled by some unusual activity on my laptop. Recently, I’ve noticed the fan running more loudly, seemingly at random times. For instance, while gaming, the fan kicks into high gear, and then suddenly, when I’m just browsing, it returns to a quieter state. This inconsistency alone raised my suspicions, but what really alarmed me was checking my browsing history today.

Upon reviewing the sites listed in my history, I came across several entries that I am certain I never visited. Some examples include ticket sales for movies like Sonic the Hedgehog and Onward from Disney, as well as various unfamiliar links related to fitness and document management services. Here are a few that caught my eye:

• Sonic The Hedgehog: Get Tickets | Paramount Pictures
• Content Management Services: Documentum and SharePoint Support
• Step & Fitness Challenges for Wellness: Count.It
• Members’ Area (CPAC)

What troubles me is that many of these sites are ones I cannot recall visiting at all, and in some cases, I even received warnings that they were unsafe when attempting to click on them. This leaves me wondering if there might be a larger issue at play.

Could it be possible that someone else is accessing my device without my knowledge? Or is there another explanation for these unexpected entries? I am starting to feel a bit uneasy about this situation and wonder if I should take further action.

If you’ve experienced anything similar or have insights on whether this could point to a security breach, I’d love to hear your thoughts. Should I be worried about the integrity of my device? What steps can I take to ensure my laptop is secure?

I appreciate any advice or personal experiences you can share!
