probably not. My advice here is to offload any files you need from her account to an external Hard drive. Delete her account. Install AVG free or another anti virus. Defrag your hard drive. Then set up a new account, connect the external hard drive, scan it, clean it, then delete that account. Defrag again, setup a new account for her and tell her to never randomly click on stuff again. For web browsing, I would setup a separate account with no admin privileges and let her use that for web surfing. Delete it occasionally and make a new account.

It sounds like overkill, but it is the best way, I have found to deal with Windows viruses. Or buy a Mac and install anti virus from the get go.
