install 3 things and you wont have a problem (they are all free for home use):
1) avast anti virus
2) malwarebytes
3) ad-blocker pro
4) CCleaner
run a scan on your system from each and you’re good to go
Add Glary Utilities as well. It free for home use, too.....................

Love my Crap Cleaner. Even though they renamed it to CCleaner.
Defraggler is also free from the same site if you want to do a good but quick defrag on your disk, should you need it.
Four thing?
Bump for later

5) Keep Java turned off as much as possible and particularly when browsing. Many ransomware attacks use Java to lock your system.
Avast, in and of itself, is a virus. Besides, ransomware is not detectable as a virus by any modern AV. Ask most security experts, and they'll tell you that most modern vulnerabilities are found in the form of social media attacks (phishing) and targeted bulk email (spear phishing). While Trojans are still in use, they're less common than they were 10 years ago.
This ransomware is particularly insidious. If you're not using ad blocking extensions in your browsers, you need to be. Our corporate IT security went to condition orange today. We are dealing with reports all over the place of users with possible infections. It's been a rough morning.
