Having problems with Blackboard Collaborate

Hey^^

I dont exactly know if ill help but ill try to solve this with you.

So you said that its acting weird...only in blackboard? (Im familiar with the site ive used it before)

Also are there any other random occurrences besides the blackboard issue occurring? And explain further on the topic of the games, you said your sister downloaded random ones but i cant seem to understand what your saying afterwards.

One way of making sure you have any malware is by using Malwarebytes Free Edition on Malwarebytes.com. Its a trustworthy program that has been recommended by critics and testers of antimalware programs. But if you do a scan or full scan make sure you pick all of the options to scan including rootkits and place the "Treat detections as malware" for the two options on potentially unwanted programs. 

I hope I can help and I hope your patient as to answering my questions, Thank you^^
