It is unclear whether my Thinkpad is infected.  There are no popups or browser redirects or rogue programs; however, computer speed has slowed.

 

Windows Lag time, after booting into windows has increased.  Does this determine Trojan infection?

 

Please explain wat I need to tell you and how to gather this information.

 

Help from experienced Computer Experts is appreciated.

 

Hear from you soon

 

Thank you
