Bitdefender adware removal system5/29/2023 Removal requires booting in Safe Mode or other built-in utilities and manual actions (B).Removal could be done in normal mode (A).Only the malware dropper has been neutralized and/or most other dropped malicious files/changes were not removed, or system is no longer normally usable dropped malicious files are still on the system removal failed (D).error messages, compromised hosts file, disabled task manager, disabled folder options, disabled registry editor, detection loop, etc.) remaining (C) Malware removed, but annoying or potentially dangerous problems (e.g.Malware removed, but some executable files, MBR and/or registry changes (e.g.Malware removed, only negligible traces left (A).The “removal of malware” and “removal of remnants” are combined into one dimension and we took into consideration also the convenience. We allowed certain negligible/unimportant traces to be left behind, mainly because a perfect score can’t be reached due to the behaviour/system-modifications made by some of the malware samples used. Sample 44 (e42de1): HydraCrypt ransomware To avoid providing to malware authors information that could be potentially useful for them in improving their creations, this public report contains only general information about the malware/remnants, without any technical instructions/details. Readers can ignore the IDs in parenthesis we mention them only as a reference for the tested AV vendors to identify them based on the samples they received from us after this test. Testcasesīelow is a list of the used samples. We randomly took and kept 45 malware samples from the pool of samples matching the above criteria. The malware must be non-destructive (in other words, it should be possible for an anti-virus product to repair/clean the system without the need for replacing Windows system files etc.).The sample must have been prevalent (according to metadata) and/or seen in the field on at least two PC’s of our local customers in 2016.All security products must be able to detect the malware dropper used when inactive.The samples have been selected according to the following criteria: Manual inspection/analysis of the system for malware removal and remnants.Run thorough/full system scan and follow instructions of the anti-virus product to remove the malware, as a typical home-user would do.If not possible, reboot in safe mode if safe mode is not possible and in case a rescue disk of the corresponding AV-Product is available, use it for a full system scan before installing.Install and update the anti-virus product.Infect physical machine with one threat, reboot and make sure that threat is fully running.Thorough malware analysis for each sample, to see exactly what changes are made.The methodology used considers this situation: an already infected system that needs to be cleaned. Most often users come with infected PC’s with no (or outdated) AV-software to computer repair stores. The test report is aimed to typical home users and not administrators or advanced users who may have the knowledge for advanced/manual malware removal/repair procedures. The main question is if the products are able to successfully remove malware from an already infected system. Of course, if an anti-virus is not able to detect the malware, it is also not able to remove it. It has nothing to do with detection rates or protection capabilities. This test focuses only on the malware removal/cleaning capabilities, therefore all samples used were samples that the tested anti-virus products were able to detect. Only products whose vendors subscribed to the 2016 public main test-series, and did opt-in for this test, are included in this report. In this test, the following 16 up-to-date Security Products were tested using 45 malware samples. The test was performed from March to September 2016 under Microsoft Windows 10 64-Bit (English). imaging software.įor further details please refer to the methodology documents as well as the information provided on our website. We advise users to make regular backups of their important data and to use e.g. This report is also intended as a little informational document to explain that professional anti-virus products do much more than just deleting malicious files. Some users may wrongly assume that anti-virus products just delete binary files and do not fix anything else, e.g. Most AV vendors may by now already have addressed and fixed/improved the next releases of their products based on our findings in this report. On the other hand, a product with low detection rate may not even find the infection and therefore not be able to remove it. However, a high protection or detection rate of a product does not necessarily mean that a product has good removal abilities. Good malware detection is very important to find existing malware that is already on a system.
