Firewall is not functioning – Windows 7

Asked By 50 points N/A Posted on -

Hi friends,

I have recently purchased a Sony Vaio Z series laptop with operating system windows 7 ultimate x64. The other day I was trying to install the McAfee SAAS on my system, but the windows firewall was switched off. I tried to switch it on but I could not. I have seen my virus and browser protection, and it is functioning perfectly, but I cannot switch the firewall on.

I tried to fix it up by pressing the FIX button but of no help. I also opened the "product details" section to switch it on, but is not working.

I am using the firewall with engine version 0, but my McAfee Firewall version is I also tried to reinstall McAfee software by first uninstalling it using the MCPR removal tool, but with no effect on the firewall. It remains switched off. I also checked my system for any kind of viruses and infections using the Anti-Malware tool Kaspersky TDSSLkiller, but I detected not a single infection.

Now I am planning to make a manual update and let McAfee install the firewall again but when I try to remove it first from Programs and features, I always see the following error message on my screen:

Script Error

An error has occurred in the script on this page.

Line: 774

Char: 35

Error: The value of the property 'Start' is null or undefined, not a Function object

Code: 0


Do you want to continue running scripts on this page?

Yes   No

I have been using this software on many 32 bit machines, but this was my first experience installing it on a 64 bit system.

I had no problems with the software on 32 bit systems but why is it behaving like this on a 64 bit machine.

Has anyone also encountered this problem before? If yes please guide me to resolve this issue.

Your suggestions and ideas are awaited.

So you’re saying that you have 2 antivirus programs? First try to know if both of them actually can work together. If so, try uninstalling both of them because sometimes antivirus programs can disable your computers' firewall so that the firewall of the antivirus can work in itself.

Then try to fresh install both antivirus programs one at a time and complete each of the antivirus’ updates. On the other hand, here is the solution for the error that you are getting; after the reinstallation of your McAfee software go to:

And then, login using your details.

Then click on the utilities tab and select “Migration and Optimization” and click download under the “Cleanup Utilities” and run it on your computer. Then delete McAfee related entries from start > run > temp and then select all the files and folder under that and delete (ignore files that cannot be deleted).

 Then delete McAfee related entries from start > run > %temp% and then select all the files and folder under that and delete (ignore files that cannot be deleted). Then reboot your pc. After the removal, log in again in at the same site as above but this time you need to log into the online security center of the same site selecting “Costumer Login” on the top. Select “Utilities” tab at the top and click install and select the “url installation”. Select install protection onto the new computer.

After which, download and save the Topsbdm file to your desktop. After installing what you downloaded restart you pc and do a manual update.

I hope this helps.

Hello Dear,

First of all, of course you should know that you cannot use all the software that you have used in 32 bit system to a 64 bit system. Sometimes, they can be used, but mostly it shows quite failure. But, don’t worry, you can find or I can say get those 64 bit compatible setup file in the internet.

Again, I like to recommend you to run a free scan of registry error at first. You can take help from tune up utilities or advance system care pro to do it

Now, there should be no problem in updating that component

Thanks for having your time
