emergency help needed to against hacking!
My home network maybe hacked. I use Linksys wireless router to connect my desktop (cabled) and two laptops (wireless) yo share the internet. Yesterday evening I noticed when I tried to switch off one laptop, it asked me : there is a link to your computer and if you switch off, the link will be off, etc. Then I noticed a small hand beside my C dirve in 'My computer'. I turned off the computer then back again. I checked sharing property of my hard drive. is was opened to share in the name of 'C$'. I changed back to 'Do not share this folder'. Also I checked desktop, it was the same and I did the same again. This afternoon, I checked C drive about half hour after I turn on the laptop. It was fine. But after two hour surfing, I noticed the computer became slow. The I checked C drive, it became sharing again but I did not see the small hand. I rushed upstair to check my destop (It was on as well), And I saw the same thing. Very bad feeling, isnt it?
Both desktop and laptop use ZoonAlarm as firewall. And the security set as high.
Can anyone confirm me I was hacked or not? If it is the bad news, what I can do to prevent it?
Thanks in advance!
