DriveCleaner Infection?

I'm working on a laptop, my AVG scan runs every morning but if for some reason I don't log in in the morning the Scan runs as soon as I log in despite of the hour.
Yesterday I got the DriveCleaner pop up in the form of a warning: "NOTICE: You have not completed the scan. If your computer hast tracks of all adult sites you have visited and files that get installed by themselves while browsing, it can violate your online privacy and could compromise your marriage. You need to clean up all the temporary and history records of your computer to remove these tracks. Would you like to install DriveCleaner to scan for and, if found, clean these browsing tracks down? (Recommended) OK CANCEL"

This happened while AVG scan was running.

I clicked on the "X" to exit the warning, instead of using the task manager. Then it opened a firefox (minimized) window and another message (which I show in the next post) this time I closed them using task manager.

I opened a new firefox window and typed DriveCleaner in the searchengine, then the previous window with the 1st warning popped up again (closed them with Task manager too)

I own a PC also I logged in there to look for info and that's how I found you. I don't know if I got infected or not, I haven't gotten the warnings/popups again.

I followed instruccions and ran everything of the thread "READ AND RUN ME FIRST". When PandaActiveScan finished the scanning process it didn't find any problems, also it didn't give me the option to "See Report", That's what I don't have one from that step.

ON A SIDE NOTE: That night while I was reading this forums (in my PC not laptop) the AVG started the routine scan my PC always gets slower, so I was looking for the word "drivecleaner" in your forums and the DriveCleaner pop-up showed up, I know that's a another story and I'll have to run the same steps to get logs of that PC but I thought it was weird that I got this DriveCleaner warnings on different computers when AVG was running, if that mean something yo you guys. I'm confused

Thanks in advance for the help...
