So, I believe my computer has been infected with a virus. It started acting up last night after I downloaded something for my brother’s Innotab… So, I restored my system a couple times, and I was even Safe Mode with Networking, because a virus protector pops up, scans, then tells me I can delete the unsafe stuff if I buy its software… well I’m using Microsoft Security Essentials, and now i guess it’s not doing it’s job anymore. When the virus protector pops up and starts showing files and all of that stuff, I can see “Trojan” something, and “MyWinLocker” included in this. Is MyWinLocker a virus? I’ve restored my system about ten minutes ago to a time an November, and so far nothings popped up. But I don’t want to risk it AGAIN. So, is MyWinLocker a virus, and how do I delete it if it is? How would I know if some websites are viruses?

Try scanning your computer with Malwarebytes. What I’ve found is while antivirus software is good for viruses, it’s not that great with spyware/malware.
Malwarebytes is the best anti-spyware/malware scanner/remover I know of. Download Malwarebytes FREE (as you only need it to scan and clean in your situation, otherwise the PRO version has real time scan but it’s a PAID version). I have used Malwarebytes at various client sites in the past and it has always been good at picking up nasties and removing them that antivirus software such as Symantec, Trend and NOD32 were unable to do.
Try this:
1. You’ll need Malwarebytes, so if you haven’t already, download Malwarebytes from http://malwarebytes.org or http://bleepingvirus.com/goto/malwarebyt… (either one will work)
2. Restart your computer. When your computer starts up, after the BIOS/logo screen, press [F8] and choose “SAFE MODE with Networking” (*very important!*). Install Malwarebytes on your computer. Now update Malwarebytes.
3. Open Malwarebytes and do a **FULL SCAN** (you must do a FULL SCAN) from Malwarebytes and wait for it to finish. This will take some time to complete so be patient. A Full Scan will scan more files and pick up more things than a “quick scan”.
4. Remove/delete all the nasties it found then reboot your computer again in *SAFE MODE*.
5. Run a “FULL SCAN” again from Malwarebytes in case there are more infected files that didn’t show up the first time as generally deleting the first lot of infected files ‘unhides’ more files which are infected.
Let me know how you get on and whether this has fixed it.
