Problems with a keylogger?

Do you know which is the best program to see if I have a keylogger installed on my pc? I think an ex internet friend sent me some attachment via email or via an instante message from Yahoo Messenger. I think he tried to use my Messenger when I was using it and I don't know, but I was having problems with my pc, it was too slow, sometimes it looked that I had two Spy Sweepers, well, something is wrong. Can somebody explain me if I have a keylogger, the way I can get rid of it? I did a recovery with the original disks of the pc but somebody told me that sometimes the keylogger remains no matter if I did a recovery (?). Please, helppp!!! Thanks

If I thought I had a keylogger, I would first run a full system scan with a fully updated anti-virus (you do have a fully up to date anti-virus, right?) and then any other free fully updated anti-malware programs I had like Spybot, Ad-aware, Ewido and A2, for example.

Ad-aware- http://www.lavasoftusa.com/software/adaware/

Ewido- http://www.ewido.net/en/download/

A Squared (A2)- http://www.emsisoft.com/en/software/free/

Then after running all those scans, if I still didn't find anything, but was still suspicious (and it's possible a keylogger could be missed by all the aforementioned programs- including your anti-virus) I would probably try downloading and running the free trial of SecurityTaskManager and one or more of the free rootkit scanners like RootkitRevealer and F-Secure's Blacklight beta.

Thanks to both of you for your responses and help. And for you, Spindoctor, yes, I did a complete scan with my Norton Antivirus (I use NIS 2006) and with Adaware but nothing to be worried appeared on the scans. For protection I use Anonymizer, too, for my privacy navigating and my email accounts. Right now I have disabled the Spy Sweeper because, I don't know why but was consumming a huge amount on my pc's virtual memory. I don't have downloaded the messengers (Yahoo and MSN), I'm waiting for the program that I want to buy.

I decided to buy this program SpyCop, I looked everywhere on internet and here on the forums, for feedbacks and comments, and I think is good, or not? All of you are the experts, I'm not, that's why I'm asking for counselling, because I know you have experience on this.

I'm glad of your responses and it helped me a lot, really. Thanks and I'll write about what happened with my pc and the SpyCop. Hugs.

 

SnoopFree, Online Armor or ZoneAlarm pro will detect keylogging behaviour.
For kernel based keyloggers, u need to run a RootKit scanner I think.

 

Bit Defender Rootkit Uncover is a beta and free. It might be worth trying. I am using it, although it has not uncovered anything, and I like it that way.
