I'll be happy to help. Malwarebytes
is very new and seemingly very reliable program that scans for malware, spyware, virii, and does one heck of a good job doing it. Does not have to be registered as long as you don't need the Protection Module which in reality very few people need and so as a result is free for use. It also is very fast comparatively speaking compared to most other malware scanners. Another is SuperAntiSpyware ( get the FREE version, it is all you need )
, it's is a bit slower then MalwareBytes, but works well in conjunction with Malwarebytes. Suggest you install both, scan and clean if you suspect any activity that seems suspicious and even if you don't suspect any activity as many malwares lie dormant and unnoticed by most antivirus programs.
The antivirus of choice in my opinion is AVAST HOME FREE
, not the AVG that so many people are tricked into downloading because it is advertised so heavily. I've been using Avast for over 4 years now with no complaints, but as with all antivirus products I have tried, malware will sneak around it. And so the need for a the Malware scanners above as once the Malware scanners engage and starting doing what they do so well, a good antivirus will jump right up and join in the fight against the malware/virus. It's a beauty to watch all three programs going after an infection.
Now after the first scan and clean, reboot the computer and do the scan and clean at least one more time for comparisons sake and to allow some confidence in the better operation of the computer. Don't be afraid to do this more then twice if you feel you need to as it shouldn't hurt anything on your computer and should leave you with a computer that almost runs like new asssuming your only problem was a malware/virual infection.
Avast Home Free initial download give you 60 days of free updates, but a FREE registration gives you the next year and can be re-registered each year for free. Like I said, been doing for 4 years plus now. Website will explain registration process, simple as pie and you will love that fact that you did. I don't work for Avast, I just appreciate good software.
Personally if I were you, I would run this software now before doing a restoration just to see what it might find. Restoration of a system especially a Sony system is a long tedious operation best avoided if at all possible. Make sure you only have ONE antivirus product on your computer at a time as having two will cause conflicts and huge performance drag on the system as both antivirus products would be trying to gain independant access to files for scanning. Not a pretty sight and a huge P.I.T.A.
If you have problems de-installing Norton, come back as I will give you sites that will address that issue with Norton.
