Avast AV detecting wrong files as viruses
« on: February 11, 2012, 07:14:26 PM »

 Hi all,

 I have windows XP SP3 installed on my PC and my avast AV version is 6.0.1367. The problem which i am facing is that avast is detecting the trusted programs/softwares as viruses. Most of the time it detects internet explorer dll file as a malware and include the dll into its virus chest list due to which internet explorer doesn't run or open and i have to re-install the internet explorer again. Same is the case with adobe reader and other softwares.

How to get rid of this?

thanks
mhs100

have you tested the file(s) detected with an online multi scanner ?





upload suspicious file(s) to www.virustotal.com and test with 40+ malware scanners
when you have the result, copy the url in the address bar and post it here for us to see

you mean that "Win32:MalOb-FE[cryp] and win32 Ramit" can't be wrongly detected? ... just asking...

Ramnit is a file infector and MalOb-FE detects accesses to suspicious mem blocks.. both detections are out some time and there were no issues so far... i really believe that it is a valid detection in this case ;)

a VT scan would be good to confirm it
