pls make this clear to me. some expert say that if you want to have 100% malware free is if you will clean install your pc after you got malware. i assumed that they are expert btw. what if you need your data?? let say i back up my data and do clean install is it useless if i restore my data to my new installed os computer becoz i assumed that there are still malware in it?? or is it easier to remove a malware if its on the backup media and scan it using anti malware program??
