I've been trying to figure out where all my memory is being used up, so i've been going thru my hard drive and found all these files in my windows folder and in my system32 folder that have names like"26133viruszb59" and 3z19hacktool359.ocx" and "3z96thief2435.dll". all different variations with the words: virus, backdoor,trojan,steal,spyware,addware,threat,etc.over 300 of these files.when I float the mouse over them, some are identified as activex control files, some are bin files, but most just say the date they were created.What are these things?Are they damaging my computer?Can I delete them?
