It depends on how 'sneaky' the malware is, and if you hire someone that will most likely fail to remove every instance of the malware, chances are, it will come back again, and by the time you let them know what happened, they'll have gone to scam someone else. So if you're looking for an expert that doesn't mess around, you should hire me; it's for your own good, since my services cost 25 times the bid amount, but I'm willing to accept your maximum budget as a "Try before you buy" kind of thing. Feel free to ignore my proposal if you think I'm bluffing. Cheers! :D
