virus help

[jpwhre]

so i had a pro unlocked, and flashed using on cricket for 6+ months. 1 day while using nrg rom, i started getting black screen, then started getting screen acting funny and image of home screen mixing up and acting funny and jumping. dismissed it as an old phone, burnt up and done. well i switched to sprint, bought fresh and new device, ran for 2 days stock and locked. Yesterday i unlocked and flashed it to nrg. tooday i tried to respond thru phone to a thread here and while "manage attachments" it blacked out. first thing i did was pull card, put in pc and scan with norten. came up with 1 infection and fixed it (as many times i tried, it wouldn't give details on what it was) i then flashed tech 1 rom just to get nrg off and stil get black screen. how do i rid the virus off both devices? it must have embeded it's self on devices an pluging into pc, thru my computer/mobile device, i cant run norten. i was running flexlis antivirus on first device and still got hit. please help, i want to stay with sprint, and don't want to replace phone after 3 days.
