ok this might be long! first, i got antisoft on my computer. i downloaded malwarebyte's for the first time and it got rid of it... for a few days. next i got what i think was called XP antivirus. this was a bit trickier to get rid of as i had to rename malwarebytes files and extensions, but i eventually got rid of the fake antivirus. THEN, last night, i got yet ANOTHER fake antivirus program. only this time it won't let me open malwarebytes at all, even after renaming the program. i somehow got it to work in safe mode (it wasn't working responding earlier) and i ran a scan and the results said that there was no malware on my computer. i went to the quarantine tab and deleted all the of trojans etc. from previous scans (this all happened within this week) but when i restarted my computer in the normal mode the antivirus was still there . i still can't open malwarebytes in the normal mode, even after renaming it, so i can't run a scan in there. i really don't know what to do, the only way i did everything else was through lots and lots of googling and step by step instructions; i'm not the most knowledgable about computers any ideas?
