I keep getting random detections when using firefox. It happens at random times when I go on several different sites, including msn.so.uk and youtube. The AntiVir Guard pops up, sometimes multiple ones pop up at the same time. It says the location is in C:\Users\(Name)\appdata\local\mozilla\firefox\profiles\0hx9b20k.default-1411137696774\cache2\entries\A719F3A50F260517B3A92A319000B1F4E63F50D3

Says it contains recognition pattern of the HTML/Crypted.Gen HTML script virus.

(there is also another detection which pops up, same cache2\entries folder but a different number. It has a different HTML/ recognition pattern but I cant remember exactly what it says. It is still .Gen though)

I have the options to move to quarantine, delete, rename, deny access and ignore. No matter which of these I select it comes back. If I tick the box at the bottom "note action for this file (dangerous)" and select one of the above it still comes back.


I have searched the mozilla site, microsoft site and google to find a solution. I have ran multiple Avira and microsoft security essentials full scans. As well as runing both of microsofts malware scans (all ran both in and out of safe mode). None of them find any issues at all. Some information I found was telling me to clear the cache etc, I did this as well as reinstalling firefox.

Hoping someone might be able to help remove this problem.

Thanks

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Thanks for the reply.

I had scanned for malware using two tools from the microsoft site, including the microsoft saftey scanner, but neither found anything. Same for security essentials and avira.

At first glance it appeared to have worked, however I am now getting the messages again despite not having downloaded anything and the only 2 webistes I went on were uk.msn.com and youtube.

The other message that I am getting says it contains a pattern of the HTML/infected.WebPage.Gen Again inside the same folder within Users and eventually mozilla\firefox

Thanks for the reply.

I have cleared the cache a couple of times now and it still comes back.

Just tried it again there. cleared the cache to showing 0bytes, closed down/re-opened Firefox and when my home page (uk.msn.com) opened up, Avira instantly gave me the warning "HTML/infected.WebPage.Gen"

it says that the files are in the cache2 folder within Users etc, so i dont know if that is different to the cache being cleared?

From https://support.mozilla.org/kb/Firefox+cache+file+was+infected+with+a+virus

Because the files in the cache are temporary, you can permit the anti-virus scanner to delete the file if it's in your Firefox cache.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

Seem to have 'fixed' the issue by lowering the amount of MB space dedicated to the cache to 0. Appears to stop the two files being created. Although am still curious as to why they were being created in the first place.

Thanks for the help.
