well i ahve my computer pretty well secured but the other day i was browsing and i get this pop up saying i have a virus (AVG Free told me)... it said SpySheriff.html is a trojan and is located in C://Windows/system32/SpySheriff.html but i click for it to be sent to the vault and deleted but i was wondering because ive had this same exact virus before lol and i got rid of it but this time it tried to change my desktop but didnt install any other trojans thank god but do u think it could have spread even though i deleted that html file?
