Hi Sanna
Are those are legit files, however some of this files do related to various trojans, worms, We just cleaned your log and I saw no evidence of any of these running on your system,
For a peace of mind not a bad idea to run a couple free online scans,
Go Here
BitDefender Scan Online
Run a scan with BitDefender , Be sure and Check Auto Clean. Make a note of anything it can't remove
Next
Go here
Trend Micro - Free online virus Scan
Be sure and check Auto Clean before you do the scan. If it finds anything that it cannot clean have it delete it or make a note of the file location so you can delete it yourself.
Not a bad idea to run an online scan every couple of weeks just to keep a double check on things, Of course keeping your Anti Virus up to date and running a weekly scan is important, Along with keeping Windows updates in order,
