My dad’s computer was infected with these malwares: Error Cleaner, Spyware & Protection, Priracy Protector and who know what else. He had his friend came in and fixed it. Everything back to normal all look clean and run normally. But when he turn his computer off for a night the next day I turn it on the window security warning kept popping up: “Window security Alert: Window has detected an Internet attempt…Somebody’s trying to infect your PC with spyware and harmful viruses. Run full system scan now to protect your PC from Internet attacks, hijacking attempt and spyware! Click here you download spyware remover for total protection” I kept clicking cancel but it kept coming back (out internet connection was even connect at this point), so I click exit but still the window kept popping up. After a while after I click exit the window security warning another window pop up “Spyware Alert: Security Warning! Worn.Win32.Netsky detected on your machine this virus is distributed via Internet through e-mail and Active-X objects. The worm has it own SMTP engine which means it gathers e-mails from your local computer and re-distributes itself. In worst case this worm can allow attacker access your computer stealing passwords and personal data. This process should be removed from your system. Type: Virus System Affected: Window 2000, NT, ME, XP, Vista Security Risk (0-5): 5 Recommendations: click yes to remove it from your PC immediately.” It wouldn’t let you click exit only option of Yes or No. If you click Yes it will trying to open up IE browser trying to connect to a website (but couldn’t because internet connection was on). If you click No it will go away for 20 second or so then the balloon pop up from the taskbar: “Window System Alert: System detected virus activities. These may impact the performance of your computer. Please, use recommended antispyware software to protect your system from parasite programs.” Then the cycle kept repeating. (at the moment Norton Antivirus is still running, Window firewall is on). So I downloaded Ad-Aware 2007 and run it. I have to run d-Aware scan twice before it found the infection and got rid of it. I try re-boot the system to see it came back or not. Everything seems fine. Just incase I ran Norton scan and Ad-ware a few times to make sure. Didn’t find anythings. So I let my parents use theirs computer normally. The next day the symptoms start again. My dad finally decided to re-format his computer. So before he do that I kept looking for help finally found this TechSpot forums. I read through the “Viruses/Spyware/Malware, preliminary removal instructions” thread. I followed instruction step by step until step 11 where I run “Panda Antirootkit programme” PAVARK.exe (We use Window XP Home edition with service pack 2). I tick the box that say “In depth scan” and then “Start Scan”. It told me it need to restart the computer before it can run scan. I click ok. When the computer load up the desktop it re-boot itself again, then it ran scan disk checking for errors. There were many parts for files that invalid and the window try to correct the file and recovering the files and kept on rebooting after about 9-10 times of rebooting, made correction to the files system. It stop and Panda Antiroot Kit start scanning as soon as desktop finished load up. But it couldn’t find anything. I found it a bit odd. Is it ok to continue step 12? Or do I need to re-do everything form Step 1 again? also At the moment the computer seem to run fine. Thank your for take your time reading. I’m really need confuse right now.
