I just went through the same frustration. My other computer got infected yesterday. It comes up with something call "ThinkPoint" and locks up. I went the McAfee support on-line. They said I have to pay extra $$ to fix the problem. Unacceptable. I'm trying to do system restore now. I'm not going to renew and switch to Norton
I got hit yesterday with thinkpoint. Had to go to bleepingcomputer.com, they have an excellent guide to remove it.
BTW there is NO antivirus product that is 100% effective, I have Mcafee and it did not catch it, but I have had other
brands in the past including norton and gotten a virus infection. Stick with Mcafee, in the long run it is best.
I moved this provisionally to Malware Discussions > Home User Assistance as that what the thread has now become.
I suggest everyone reads this document: https://community.mcafee.com/docs/DOC-1294
To the original poster a Firefox update alone shouldn't have caused problems unless your firewall and/or antivirus were turned off or turned themselves off somehow.
You could try in "Safe Mode with Networking" (reached by tapping F8 repeatedly while booting up) downloading, installing, updating and running the free version of THIS tool.
Other than the above all I can suggest is running Hijackthis and posting its log on one of the following independent forums for expert guidance:
Do not post Hijackthis logs here, we can't help with those!
Post the logs at a specialist Forum:
Be sure to read all the sticky announcements/instructions at the top of each malware forum!
A footnote: When updating anything or leaving the machine unattended for any reason always make sure that nothing else that requires an internet connection is running, IM's, Chats, Social Networking sites, Torrents etc.
Marty, you should know that Norton fails to detect such rogue programs as ThinkPoint quite often. I know this because I had Norton Internet Security and it failed to detect a rogue program called Security Tool at least twice. You can choose mcafee, norton, kaspersky or any other software, there are no 100% protection. So, if the mcafee failed to detect this virus, then just use malwarebytes, superantispyware or spybot to remove thinkpoint or any other rogue program from your pc for free.
