Basically, it is excessive antivirus after poisoning, that is, antivirus kills or isolates many system files!

Explorer is not the first to run after the system is started, and the previous programs can't continue. Running a lot of big games is only about hardware!

XP system restore is actually very impractical, far less than GHOST, and many restore problems still exist!

I often encounter problems after poisoning and antivirus.

The best way to solve the system problem is to reinstall. It is difficult for any expert to repair a fragmented system!

I think your system is on disk C. It is unwise to put papers, materials, programs and databases together. We can start somewhere else, like d.

Set up a new system and transmit or save data!
