What version Windows are you running? Pentium 2 and 416MB of RAM? That goes back to the 90s and Win95/98. If you’re running Win10 or Win11, the most unobtrusive package would be Windows Defender, which is built in. It’s capable. It’s not the best, but it’s capable.

I’ve never seen a plastic film on a screen that wasn’t meant to be peeled off. They’re usually to protect the glass and keep it clean. If it’s optically fine, you can keep it on if it doesn’t bother you.

If you’re moving from HD to SSD, I’m not sure if a cloning program would work all that well. I’d need to hear from people who have more experience with them. Even then, I’m pretty sure Windows recognizes SSDs and treats them differently. I’d perform a fresh install just so that I knew Windows was property configured to use the hardware (the SSD) to its best capabilities.

If you have any games on your boot drive in Steam, just go into their Properties, into the Installation Files section, and move them to the Steam library on your other drive. When you reload Steam, you can just point to that library on the other drive and your games will be loaded.

Twitter/X is, basically, a private company and can do whatever they want with your postings and information. Elon Musk has shown he can and will treat accounts and postings in whatever manner he chooses. For that matter, other online services, even if not privately owned, are not government agencies and can use their own discretion when it comes to moderating content and divulging information. So it’s possible and, judging by your question and wording, very thankfully probable that your postings would be reported to authorities.

See if your laptop has a factory restore. You boot into it by pressing one of the F keys during the power up process. If it does, use it. It’ll bring it back to the point it was when you received it. If you don’t have that option, see if Windows has restore points that you can go back to time before this happened. If you can’t do that, don’t go to nVidia for drivers, go to the manufacturer’s website. GPUs for laptops are often tweaked by the laptop manufacturer and the drivers are tweaked too. Look for all the drivers for that model.

Sugar free actually does help. There is a LOT of sugar in soda, and as it dries it gets gummy and sticky and can cause more problems than things like diet soda. You said you opened it up, does that mean you looked under the keyboard? That’d be the area I’d check out. If you’re up to it and have the skills, take out the keyboard and look for soda stains you could clean up with a rag and alcohol. Beyond that, if it doesn’t look like it got anywhere else inside then you may be very lucky.
