Windows 7: Huge temp files, totalizing 30 GB, created in one single day

Windows 7 Enterprise x86
Huge temp files, totalizing 30 GB, created in one single day

hi.... im here to report a severe problem that i had yesterday... on the afternoon, i noted that the disk space has being filled up without no apparent reason... regardless of that, i continued to play games, and browse the internet... with a very slow perfomance....
5 hours later, i noted that the rhytm of the creation of that TEMP files was increasing dramatically(which they didnt have the .tmp extensions, it was just files without extension, and with names starting TMP000000 and then random letters or numbers...)
i seen that the disk has filling about 100 mb in one second, with the system very, very, very unresponsive... and when the disk reached 1 gb and counting... i immediately switched to the safe mode.... i used a program to see the folders that were occuping the majority of space in the disk, and i was totally catched up by surprise to see that the Temp folder was immensely filled up... i deleted that files, and then, i switched to the normal mode of the OS, no trace of that files again... however i have fear that they can return sooner or later...
so i need help to resolve this... i will post 2 screenshots that clearly illustrates that files...

for now, thanks if you can help me....

Hello Zeca112 and welcome to Seven Forums.

Very hard to say what's creating those temp files. You could have a legitimate program running in the background that is creating those temp files. Or it could be malware. To rule out malware I'd suggest three free on-demand programs that you could run in addition to your resident antivirus suite because no anti-malware program is 100% effective 100% of the time:




If the malware scans come back clean you may be able to figure out which program is creating the temp files by using either the built in Task Manager or running another free (and more powerful) program from Microsoft called Process Explorer.

i dont believe that a legitimate application can create those files... after all, i have few programs that are above 1 gb... malwarebytes also dont detected anything in the safe mod , not the normal one... regardless of that, i will check again.. thanks for your help....

p.s- i am keeping a close eye on the temps folder, no trace of TMP000000 for now, but it can come back after a few days... and i fear that...

Using Torrent can cause this problem. Another security program I recommend for scans is Windows Defender Off line. It does take some time.
