Suspicious new folders with chaotic jpg,sql,doc,txt and doc files
I found several new folders, each containing 10 small files with random content ( a chaotic picture, an rtf of random letters, a corrupted doc file etc...), all the files were created at the same time, owned by administrators, and accessed later. Comodo scan found no threat and I couldn't find any info about this.
The file names are weird like proposed somebody sang.xls or goldenuse.mdb.
Any idea what's this and what can be done about it?
Edit: The small files are safe according to Virustotal and Comodo. Nothing happened for 3 days.
If it's a ransomware can I install a clean Windows in one partition and work there or should I format all the HD?
