Hi senidaljeet, Your system is infected with Trojan.Fakesecurityalerts and also some Rogue Antispyware infections. Don't click anywhere to download any antispyware in pop ups. Lets start to get rid of them. Download the "HijackThis" Installer from this link: http://www.trendsecure.com/portal/e... 1. Save " HJTInstall.exe" to your desktop. 2. Double click on HJTInstall.exe to run the program. 3. By default it will install to C:\Program Files\Trend Micro\HijackThis. 4. Accept the license agreement by clicking the "I Accept" button. 5.Click on the "Do a system scan and save a log file" button. It will scan and then ask you to save the log. 6. Click "Save log" to save the log file and then the log will open in Notepad. 7. Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log. 8. Paste the log in your next reply. 9. Do NOT have HijackThis fix anything yet! Most of what it finds will be harmless or even required. Plz post your hijackthis log in your next reply for your system analsys.
