help with my galaxy tab?

[Fannio Nfianofnaisnf]

so i noticed that my instagram on my samsung tab (7.0) won't work. i uninstalled and reinstalled it and it still wouldn't work. so i restarted my tablet and it STILL wouldn't work. i just tried going to my playstore, but it won't even connect. all my other app works, just instagram and the playstore? i disconnected from my wifi and reconnected and it STILL didn't work. it worked two days ago, but it just suddenly signed me off and i can't log back in.

Since this is an android phone it appears there maybe malware or virus in it. Scan your device with an antivirus. On my phone viruses have been detected and I use kaspersky.

When the infection is cleared, instagram should work
