Someone with a history of putting commercial keylogger software on my computers gained physical access to my Windows 7 Home Premium laptop.  I took the computer to a tech place who said my system was infected with a rootkit keylogger with full admin privileges and a backdoor trojan.  Supposedly my computer is clean now but these files remain on the computer from the day that person accessed it:

You can submit files to VirusTotal - Free Online Virus and Malware Scan and they will be scanned by multiple security programs.

 

Security professionals will tell you that if a backdoor piece of malware has been active on your computer it is best to reformat and reinstall the OS.

When should I re-format? How should I reinstall? Security | DSLReports, ISP Information
