i recently used the AVG anti-virus software to scan my computer, it found six threats in the window files and it automatically deleted them. but immediately the computer showed a warning saying that important files have been changed and the computer cannot run properly without them. i didn’t dare to close the computer incase it doesn’t open again, are there any good softwares i can download to recover those files??? or any other easy ways to put those deleted files back? i don’t have the windows XP pack.
