I ran Malwarebytes from both a normal boot and also in safe mode. It found an infection and I selected "delete" but the problem persisted.
I then did a disk restore (sector restore) from an Acronis Home 2011 backup set. This backup set was made 1-1/2 years ago when there was no indication of virus activity so I believe that it is (was) a clean backup set. After installing and configuring items that had been installed after the backup set was made all appeared to be working without problems. After 1-2 days I noticed that the "T" key was not working. After rebooting the "T" worked again but another key was not working. Now there is almost always at least one key that does not work even after rebooting.
I have numerous applications installed so formatting and installing from scratch is a prolonged process (2-3 days) but I am willing to do that if that is the best recovery method.
1 Since after recovering the backup set failed is it possible that a virus is in the boot sectors or another location?
2 Will reformatting resolve this issue?
3 Should I reformat then restore the backup set?
4 Will antivirus/malware programs clear this problem easier? If so, how?
Than you in advance for your help.
