It has been a while since I posted a summary for malware removal.
Here are some steps in general you can take if you suspect there is malware on your computer:
1.) Download Malwarebyte’s Antimalware and run the free version to scan for general malware.
Remove anything you find. You can remove/uninstall the program when it’s finished.
2.) If you are paying for antivirus software on your home PCs, stop. Microsoft Security Essentials offers good protection, and is free–even in a commercial use environment on up to 10 computers.
Make sure you’re running scans regularly, and paying attention to any alerts that pop up.
3.) If you still have a problem, download and run the TDSS removal tool from Kaspersky labs.
If the tool either fails to download or run, you have a rather nasty rootkit–you’ll need to call someone for help.
4.) A word about Windows 8–it has free antivirus/spyware built in (Security Essentials is integrated). If you’re paying for it, you really shouldn’t be–even in a commercial environment.
I hope this helps. Malwarebyte’s Antimalware takes care of most threats that have made it past your antivirus scanner. Prevention is better than cure. I’ve written about proactive methods to avoid infection here.
