Let say, someone unintentionally uploaded image to a blog from their computer with virus in it or the computer already has the virus. The account or page is not infected. However malicious software — be it an image that exploits an unpatched vulnerability or anything else — has the potential to infect machines that visit that page.
Fortunately this is extremely rare. Syncronizing your account simply means that an malicious extension for example that is installed on one machine in Chrome will automatically be replicated to your other Chrome installations. You might remove it from one, but it comes back when sync happens from one of your other machines. The only solution is to temporarily disconnect ALL machines from that syncronization, disinfect ALL machines, and then carefully re-enable sync one by one.
I feel VERY stupid. Just last night I opened an email on my computer from a person that I kind of know. I thought this was something important but in the body it said Error. That is what I did. I know that everyone now is cringing. This was something that caught me off guard.
There were all kind of things that popped up on the computer that seemed bogus. The computer is fine now. This is a feature that I depend on for my smartphone. What should I do? Leo, my problem is this: I get no e-mail period. I open and closed 3 or 4 accounts, change my password, and still I get no e-mail. I have tried to sign up at different sites for e-mail, but noting comes in. I tried it with your site. Can you help. New to all this computer thing.
No one will be able to answer your question unless we know what kind of email account you are opening. The big question is, what type of email accounts you are setting up.

What do I do?
I realized about 6 weeks ago that we are having email issues at work. At this same time our Marketing company had started using Zoho campaigns to send out a newsletter from our company using my email address, they never set up the SPF record prior to doing so. And then there are some people who can email me and I get it, but it will not allow me to send anything back to them. It bounces back and says [P4] Message blocked due to spam content in the message.
They are saying its on our side. Well IT on our side is getting pissy with me saying it absolutely is not on our side — but I have to think it is.
So I am thinking we have some type of malware in our system at the office? Would that make sense to you? Honestly at.
It sent out spam emails to those who had previously sent me emails. The hack was very sophisticated. After people told me about the spam, I changed my password on the email account. This seems to have stopped the spam at least for now, I hope.
Moreover, I did several virus scans of my computer — no viruses were detected. Can someone let me know what happened? Could the service that provides me the email account have been hacked? It could be malware, but more likely your password was simply discovered or guessed. What kind of attachment are you trying to send?
