When I went to a site regarding estimated taxes MSE notified me that there was malware that it identified as severe (Exploit:JS/Fiexp.O) and quarantined it.  Should I remove it?  How do I know if any other needed files have been affected?  Should I use System Restore?  MSE has placed a MSE Checkpoint labeled "Microsoft Antimalware Checkpoint" not sure if that was before or after. 

 

Thanks for your help. 

 

Update: Ran MSE (Quick Scan) and Malwarebytes with no problem.  However, Microsoft recommends downloading Microsoft Safety Scanner and running that program as well as a full scan.

Hi! My name is zep516 and Welcome to Geekstogo!
I'll do the best I can to resolve your computer issue
Please make sure to carefully read any instruction that I give you. If you're not sure, or if something unexpected happens, don't continue Stop and ask! Never be afraid to ask questions!

It looks like Microsoft security Essentials has done its job and quarantined (Exploit:JS/Fiexp.O) before it was able to do any harm. You can remove it.

Microsoft recommends downloading Microsoft Safety Scanner and running that program as well as a full scan.

It would not hurt to run that scanner.

JS/Fiexp is a family of JavaScript components belonging to an exploit kit called Fiesta. Similar to other exploit kits like Blacole, it first checks your browser, version, and installed plugins. It does this to determine what exploit to use on your PC. It can exploit vulnerabilities in Java, Adobe Flash Player, Adobe Acrobat Reader, Microsoft Silverlight, and Internet Explorer. This threat might get into your PC if you visit a hacked or malicious website.

Next
Download Security Check by screen317 from Here or Here
Save it to your Desktop.
Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
A Notepad document should open automatically called checkup.txt; please post the contents of that document.

NOTE: If SecurityCheck aborts and you get the following message: UNSUPPORTED OPERATING SYSTEM! ABORTED! try rebooting the system and then run SecurityCheck again.

OK

All the programs are up to date too, Java, Adobe those are the programs that exploit tries to infect.
I don't think there is any more to worry about.
