Choices and then some..
In the future, if you have additional problems it would help to continue in the thread you already started. Had I only read this post, I would have taken it at "face value". While looking for added background, I came upon your other (recent) thread. It changes "the landscape".
Given all the problems you're having, I too would recommend a clean install or posting at a Malware Removal forum. While the site mchainmchain mentions is a good one, there are plenty of other's. A complete list can be found listed on the left-hand side of this page.
Only to name a few:
Lastly, I do hope you removed Advanced System Care. It's quite possible some of your problems began when you removed what it found. Please read the "Conclusion" in this review, written by one of our moderators, prior to her untimely passing.
Best of luck..
