So AVG finds a possible virus, and the best suggestion is to get another anti virus product. Hardly helpful.
Like saying to someone with a puncture to buy a new car.
I notice in the second picture it says it is in folder E:\System Volume Information. This folder holds restore points.
Every so often Windows saves a lot of system files as a sort of "backup" and these are called "Restore Points".
What I think has happened is that you have had a virus on your PC, and then Windows has taken a "Restore Point" and as part of that restore point it has included a file with a virus in it.
That is why AVG is flagging it up as an error, it found the virus in the restore point, but I guess as it is a system file then Windows will not let AVG delete it.
Two solutions:
1) Go into Windows and turn off restore points. This will delete all the old restore points. Then turn restore points back on again.
or
2) Go into Disk Clean Up and select one of the options called "System Files" I think it is. Do a clean up. This will delete all the restore points except the latest.
If the latest is clean you are ok, if it also has a virus then do as in 1 above and turn off restore points then turn back on again.
Run your anti virus again.
