Isn't it embarrassing?

I feel the same way too. My yahoo contacts mail were receiving emails from me. Soon after receiving those spams, my contacts which were mostly composed of my friends and families were asking me what was the email about. It is really embarrassing since some of my contacts are working outside the country and they were quite mystified on the emails. With that, I need to send them an email saying that the email is not coming from me. I have already changed my yahoomail password a lot of times but the problem still exists. I already opened another email and refrain myself from opening my old mail but still emails are still continued to be sent to my contacts and that the email seemed to be coming from me... I tried to dig in on what is really the problem and one of the possible reason of this is that there might have been a malware that was downloaded in our computer. In order to correct the problem I've tried to download via online on malware detection installers but was unsuccessful in doing so. I stillcheck with my friends if they have malware detection installers so I can have the malware removed in my PC if it's really present.
