Might want to check your DNS server list within your operating system. Time has come where the FBI is shutting down the supposed affected servers hosting this malware. Monday the 9th if you cannot seem to access any website by your icons or by typing in the address bar , your machine might be effected.
You should however be capable of typing in the website IP address , at the same token many will not have this capability.
You can come to testmy.net at 22.214.171.124 to get a solution in removing the DNS servers.
For now , you may want to see if your machine is been effected, please look for these DNS servers in the local list.
