Hi All

Need some advice from the experts. Run malwarebytes every couple of weeks and also Anti Virus scans weekly using Avira.

Been a way for a few weeks and this morning set them both off.

Ran malawarebytes and there was this in the quarantine. it was in a folder thats been was a copy of my tomtom that has been on the laptop since November last year, hasnt been picked up in any previous scans.

Could it have been a false positive, or is there anything we should be worried about.

installtomtomhome.exe (Trojan.FakeAlert) -> Quarantined and deleted successfully.

Any advice would be appreciated.

Thanks

    From the quarantine tab, you could temporarily 'restore' the file and upload it to https://www.virustotal.com. You can also zip it up and send to the Malwarebytes team: http://forums.malwarebytes.org/

    I would Check and Fix this in Hijackthis, unless you really want a 'torrentb1tch' toolbar:
    O3 - Toolbar: (no name) - {0BF43445-2F28-4351-9252-17FE6E806AA0} - (no file)

    Thanks

    It's not unusual for malware to infect genuine binaries.. The installer appends the malware to the end of an existing executable file in the filesystem. At the beginning of that file, a "long jump" (or similar) instruction is then inserted and that invokes the malware code..

    Either i) the above happened, and the "tripwire" detection function of the anti-virus software noticed the change in the size or checksum of the installtomtomhome.exe caused by its modification.

    Or ii) the anti-virus s/w writers have updated their signatures and a sequence of bytes contained in installtomtomhome.exe which were previously considered innocuous, is now triggering a Trojan.FakeAlert warning.

    Worth finding out for the benefit of others. If you still have the original copy of installtomtomhome.exe as supplied by TomTom, you could do an "md5sum" of both the suspect file and the original file, and a binary "diff" to spot any modifications.

    thanks makes sense now, in my hurry to get rid of it I removed it from malawarebytes and also deleted the tomtom folder as well, it was just an only back up so wasnt needed. Would you think if i ran malawarebytes again and anti virus and both were clear then everything would be ok.

    You're probably fine, unless you are having any symptoms of an infection. Follow Closed's guide as there are loads of autoruns you can disable (if in doubt, search each one or use the following as guides:
    http://www.systemlookup.com/lists.php?list=2
    http://www.bleepingcomputer.com/startups/)
