Here’s the situation. So, I was recently the victim of a drive-by download. The first thing I did was shut off my laptop, thinking that would stop it. When I turned it back on, there was a suspicious looking .tmp file in my downloads folder, and a couple more in JumpListIcons. Then, like a complete buffoon, I plugged in my external hard drive and SD card and decided to back up my files. Now, of course, I have no idea whether or not the dang things are infected.
After I backed everything up, I took the laptop off the Internet, turned it off, and haven’t really used it since (save for maybe an hour or so later that day to look at a site. I turned the Internet off again after, of course). As such, I wasn’t able to locate any new .exe files anywhere, as I didn’t give myself the time. Anyway, though, I know next to nothing about computers, so I wouldn’t know where to look, anyway.
So, what I’m wondering is:
-How do I safely check whether or not the card and drive are infected?
-What types of malware, if any, are capable of getting into things like pictures, videos, music, .html files, docx files, and .swf files? I know ransomware can target anything and everything it finds, but what about other types?
-Can malicious code hide in the card & drive themselves without even needing to infect a file?
-Should I even risk restoring this stuff if I really think it’s infected? How should I go about doing it if I decide to?
-Lastly, I was wondering how malware interacts with program-specific file types, like .psd or .sai. I draw a lot, so I’d like to try and save that stuff if I can.
Also, potentially important to note is that I don’t really care what happens to the laptop. I was gonna buy a new one anyway. I’m just concerned about my stuff, is all.
