Firstly clear out all your browser's temp files and cache by opening your browser and using Tools -> Options.
Then, click here
and download Malwarebytes.
* Double-click
mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to the following:
o Update Malwarebytes' Anti-Malware
o Launch Malwarebytes' Anti-Malware
* Then click
Finish .
· If an update is found, it will download and install the latest version.
* Once the program has loaded, select
Perform Full scan , then click Scan.
* When the scan is complete, click
OK , then
Show Results to view the results.
* Be sure that everything is checked, and click
Remove Selected .
* When completed, a log will open in Notepad. Reboot as required.
If everything is running fine now, purge your System Restore points and reboot. Then turn SR back on and set a new restore point.
If you are not sure how, just post back.
