Recently my AV has been detecting Trojan backdoors, Rootkits and Worms quite often. Some go unnoticed (I've checked suspicious files in VirusTotal a few times and they indeed turned out to be malware without the AV detecting them).
I've tried cleaning up, but in the end I decided to do a clean Windows reinstall. Since I have no other way to back up my files, I'm uploading them to cloud storage. My question is, is there a chance of the malware attaching itself to these personal files (pictures, videos, notes, etc) and once I download them to the new system to end up infected again?
