I believe a smart thing to do would be scan with Hitman Pro, SuperAntiSpyware, Eset Online Scan and Dr Web Cure it. These are all recommended to detect and quarantine harmful or potentially malicious software. I know there are a lot listed here, but it is better to ensure that your system is clean then leave a virus in the wait.
I also suggest downloading Firefox 4 (if you have a older version)
Download Adblock Plus add on (blocks redirecting ads and other nuisances)
Download WOT (Web of Trust which tells you which sites are safe to use)
Download NoScript (blocks scripts that malware use to exploit your browser and load onto the system)
This may help to prevent future infections. I also suggest uploading Sysinspector log to Eset's website by downloading the file (search for Sysinspector download Nod32). This log lists running processes and critical system files that the professionals of eset analyse, to discover any hidden rootkits or infections.
Hope this helps
