Windows action center has told me to "remove the Win32/Small.CA virus from your computer".I have mcafee antivirus but it is unable to detect it.The virus has changed some of my antivirus settings on its own. And the changes made by the virus are not reverting back.The system has become slow and my browser chrome is eithercrashing or hanging up again and again.But there has been no blue screen while booting.
With all due respect to Zohaib R, there is no virus and the link's solutions given never work, they want you to call and pay.
This is a typical bug with Win 7 action center.
Go to the Action Center (by clicking Control Panel | System and Security | Action Center) and select to Change Action Center Settings. This allows you to disable specific types of messages, including messages about Windows Update, Internet security settings, User Account Control, Windows Backup, and more.
then wt about the fact that my antivirus automatic scanning status is changing by itself , browser is crashing regularly,sys has become lot slower. And without connection to internet the system works fine bt soon as i connect it to internet it starts slowing down and hangs sometime.
There are several malware including a Rootkit which was probably came from Bit Torrent.
I noticed that you have installed several antivirus tools (Avast, Superantispyware, Kapersky, etc) along with your main McAfee. This is dangerous as all the scanning engines will create conflicts. You must delete all antivirus software and keep only one.
You have a toolbar which is called SweetIM, it is a virus. You must remove it.
Please follow the procedure below:
1 On your desktop ZHP created an icon ZHP Fix, looks like a seringe, double click to open it.
Please request a FULL system scan, which may take from 20 minutes to hours. Do not interfere no matter how long in takes. The creators of Malwarebyte recommend that while the tool is running that you go do something else, such as watching a rerun of Gone with the Wind or read Tolstoy's War and Peace.
If Malwarebyte restarts your system, launch it again to finish the Full scan.
When the scan is completed, delete all items found.
11. Reboot your machine
12. Delete the ZHP Diag log, produce a new one a and upload it on Speedyshare
(click on the download @ bleeping computer button)
2.Close all open Windows including this one.
Close or disable all running Antivirus, and Firewall as they may interfere with the proper running of ComboFix.
3. Double click on the ComboFix icon.
Windows is issuing this prompt because ComboFix does not have a digital signature. This is perfectly normal and safe and you can click on the Run button to continue.
4. Accept the disclaimer and the recovery
5.You should now press the Yes button to continue. If at any time during the Recovery Console installation you receive a message stating that it failed to install, please allow ComboFix to continue with the scan of your computer.
ComboFix will disconnect your computer from the Internet, so do not be surprised or concerned if you receive any warnings stating that you are no longer on the Internet. When ComboFix has finished it will automatically restore your Internet connection.
While the program is scanning your computer, it will change your clock format, so do not be concerned when you see this happen. When ComboFix is finished it will restore your clock settings to their previous settings.
If you see your Windows desktop disappear, do not worry. This is normal and ComboFix will restore your desktop before it is finished. Eventually you will see a new screen that states the program is almost finished and telling you the programs log file, or report, will be located at C:\ComboFix.txt.
During the process, please do not mouse click nor must you tap on the keyboard. Let the tool run.
