XP issues - virus/malware or bad sys update?

I have a XP system that the toolbar does not show open programs, services do not seem to load at boot, the date is off by one month, I cannot paste
anything that I copy, and system restore does not work. All of these issues
started at the same time a few days ago. Has anyone else seen this group of errors? I am trying to resolve and do not know if it is a system update
gone bad, or if maybe it is a viruse/malware issue. Please let me know if
you had had these problems together and what you did to fix them.

 

I was thinking it was a virus/malware issue so I have started running the basic scanning steps first. I will let you know if there are any new developments.
