|If your computer is infected it is never safe to do any online banking (Or use any secure sites that need password login or need sensitive information).|
The malware is using a random file name to prevent detection. Your antivirus program detects the malicious script embedded in it.
My preference is to run free anti-malware applications to see if they will clear it up first.
Free online virus scans / removal:
Free adware / spyware scanners:
Once the programs have downloaded update them then run the scans. You can also run them in safe mode for a higher chance of success.
