PB Launch

Everytime I launch my PB launcher it always ask for me to click "Check". It's really annoying, now after I click check it'll run as normal but if I don't click Start after the check asap it will ask to click check again. Like wu du fu?

Steps I already did:

-uninstall reinstalled PB
-restarted PC
-run CC cleaner
-my PC has no deepfreeze or any apps alike

Any help or suggestion would be greatly appreciated

It is caused VIRUS, you must reformat its Windows
