    ...So a while back I had somehow gotten a virus called "Theodore.exe" on my computer, and at first it was super annoying, kept opening itself in the background and installing a bunch of programs, but not really doing everything else. I turned off its startup settings so that it won't do that again after I uninstalled all the new and affected programs and ran multiple antivirus programs, but it's still there apparently, just doing nothing. There's like 12 copies of it in my task manager but none of them have a file address and no amount of antivirus scans can get rid of them. It kind of makes me feel like Theodore might've connected my computer to a bot-net, but I really hope it's just as dead as it seems. Either way, it's a good thing I'm planning to get a new computer soon anyway.

    There's this computer virus I remember causing a lot of trouble for some of my friends in I think it was 2009/2010-ish. It was an annoying one that spread through Skype where if you were infected with it, it would say something to trick you like "hey, you gotta check this out" or something then post a suspicious link. My first friend who got it contacted me before I saw the link outside of Skype informing me to not click the link he sent because it will install a virus onto my computer & that some of our group had already been infected. It seriously felt like a scene from a horror movie. That caused all sorts of issues for him & eventually, he was without a computer for a while. A similar virus showed years later that spread through a different group I was apart of & I recognized the sort of way it presented itself so I knew not to click the link & I helped inform people that it's dangerous & to not click it although it was too late for some members of the group. Do you know anything about the viruses that spread like that through Skype? They're outright annoying, I mean I know to not click those links so having them sent to me isn't the problem, what is would be that the people who suffer from it are very embarrassed & have to try & get the word of warning out to all their contacts before the link is clicked & some of the friends who care such as me feels obligated to help so I'm usually trying to get a hold of people I know who are friends with the victim on Skype to give them a heads up before signing into the program. Luckily as someone who had lost contact with people through the closing of some forums & so on, I know to get more than one method of contact from people if I can help it so I just have to remember who checks what more often & who would be where before signing into Skype. I also send a message to them on Skype just in case they happen to check that first thing.

    If you use Windows you can watch my video on proper security practices in Microsoft Windows. The reason so many Windows clients get infected is because people are browsing the web with their administrator account. That's the equivalent of using your root account for everything in Unix or a Unix-like system and I'm sure you know how terrible of a security practice that is. Always browse the web from a standard user account instead of your administrator account.
