Malwarebytes full scan took 10 hours to scan 30 Go ... help !!!

[maba]

Malwarebytes is a very great program but i have trouble to finish full scan with the latest updated version...

On a pc under vista with a q6600,asus mb, sata hd ... no problems, full scan took 1,5 hours ... everything is fine ..

On my other old pc ... P4 3.2GghsHT XP PRO asus p4p800 socket 478 DD IDE, norton antivirus, ..., malwarebytes full scan take 10 hours ! for 30 go !!

I have chek all my hardware and all is fine (hd tach; cpu test etc) ...

is it normal for malwarebyte to take this time to scan 30go on older configuration ?

and in any way ! thanx to this wonderfull program who saved me against evil trojans )

thanx.

MBAM is designed to remove malware as effectively with a quick scan as it will with a full scan. It's hard to say what might have gone on without a log. What drives did you scan? C or what ever your main drive letter is would be all that is really needed to scan. Scanning the DVD/CD drives is pointless.

The only thing I can think of that drastically cuts into mbam scan time is large amounts of temp files...

He might want to try atf-cleaner, let it remove alot of junk files... Then try scanning again.

If a quick scan is just as effective as a full scan, why does Malwarebytes recommend a full scan when an infection is initially detected? If it was just as effective, why is there a need for a full scan in the first place ?

Full scan is done only on my c:windows partiton ... my pc is clean (no temp files, no dump, etc ...) ; "c:" have 174 003 files and 12895 folders...

I remark it took long time to scan .jar .rar etc ... all compressed files ... some folders windows are so long too...

at the begining of mbam process it took 50% process and 32 mo ram ... (maybe scan regisrty)

very quickly, it took 00 to 10 % of processor (it stay at 00 when the program scan a new file...it goes to (1 to 7)% then return to 00%) and the scan keep going ... but it is very slow ...

raising process priority don't help ... i raise it to real time , then high ... then when i canceled the operation of scan, mbam stop responding and a windows "windows defender" say me if i want to send c:\windows\drivers\mbamswissarmy.sys to microsoft ...

maybe windows defender cause troubles to do a rapid full scan on a xp sp3 system or maybe it's just a crash because i play with the process priority ...

it's very hard to know why mbam is so slow on this pc ! and maybe it's the normal time to scan 174 000 files ...

thanx to you all

Usually it takes me around 30'ish minutes for me to do a full scan of a hard drive with around 50,000 files (if I can remember what the count was). So, just have to take into account the processor speed and what all is running at the time..10 hours does seem like a little excessive.

thanx for your reply !

i have "fixed" my problem by doing full scan in safe mode ...

surely a third party program who don't like malwarebyte ... but it's very hard to know who ...

so ... in one way, i can do a full scan in a "normal time".
