If the antivirus installed on your computer does not detect anything suspicious, but symptoms are evident (freezes, incomprehensible running processes, autorun.inf appearing on flash drives, etc.), a "one-time antivirus" is required. It's easy to handle it - just download from the link and run. In this case, during the scan, it is advisable to disable the antivirus, which is installed on a permanent basis.
1. Free. For home use, almost all disposable antiviruses are free.
1. They are not able to protect your computer all the time (there is no module for real-time protection) and there is no update of the anti-virus databases.
2. You have to download it again every time so that such an antivirus detects new viruses.
Dr.Web CureIt! is a good disposable antivirus. Knows how to deal with running viruses (does not allow himself to be killed during scanning).
An online antivirus that scans all computer files with 68 antivirus databases. How to use it, I told in a separate article.
This is a good option if you have unlimited internet.
Minus: cannot disinfect infected files.
A plus: you do not need to download again to check, the databases are always fresh.
Plus the Online Scanner - no need to worry about downloading new versions with fresh databases. Just open the link or run esetsmartinstaller_rus.exe, the antivirus will start, update and check your computer for viruses.
Norton Security Scan is another one-time anti-virus. You can download the interface is English, but simple.
Checks hard drives very quickly. Requires a connected internet like Eset Online Scanner.
On first launch, it creates a shortcut to itself, which is strange.
In general, it is better not to use it, since viruses widespread in Russia get into its database a little late. The newest vinlockers (ransomware banners) are unlikely to be found.
Powerful anti-virus utility (not a full-fledged antivirus!) for advanced users. The functions are not the sea, but the whole ocean.
Earlier I already talked about how you can use special programs and online services. If you haven't read that article, be sure to check it out. In it, I talked about the most popular and effective verification methods, they are relevant to this day.
Today we will talk about several utilities that are kindly provided to us by the developers of the well-known Doctor Web anti-virus. Namely, we will consider the principle of operation of the popular free scanner Dr.Web CureIt and its brother, the online service "Dr.Web Online".
Both options are for a one-time test and work without being installed on the system.
And so, let's get started.
Dr.Web CureIt! - the developers position it as a free curing utility that can fully scan and cure your computer from the most popular viruses. But it is not so. Undoubtedly, Doctor Web Kureit takes a leading position in detecting threats, but as a treatment, he only proposes to remove the found threats or move them to quarantine.
And only in some cases, it actually performs the treatment, for example, when the hosts file changes, when the message "" pops up. But here you need to be especially careful, because if you used any unlicensed software with a key on your computer, then there is a possibility that after the hosts file is disinfected, it will stop working.
How to use the healing utility correctly:
Upon completion, remove the found threats and restart the PC.
In some cases, it is recommended to scan through Safe Mode. This will increase the efficiency and speed of the scanner. Because, while working from under Windows, malware can block or slow down the work of Doctor Web.
Dr.Web CureIt utility is a portable version of an anti-virus, a so-called scanner that works without being installed on the system. First of all, it is intended for a one-time computer check, albeit a regular one. It does not have special modules inherent in its composition, which means that it will not be able to provide constant protection for a PC or laptop.
On the other hand, Doctor Web is equipped with the latest virus databases, which makes it possible to identify the latest threats. Its main advantages are: free, high detection rate and fast scan speed.
Also, it does not conflict with other installed antiviruses.
By using free online scanner from Doctor Web, you can perform only a partial scan of your computer for viruses. Its task is to scan uploaded files with further output of the result.
Compared to the previous utility "Dr.Web CureIt", no actions will be applied to detected viruses. It is necessary to treat infected files yourself.
Another disadvantage is the small size of the downloaded file, which is equal to "10 MB". Load more will not work, which may not seem very convenient. But I want to believe that this volume will be increased in the future.
The main advantages of Dr.Web Online are:
On my own I want to recommend using both options, even if you have some other third-party antivirus installed. This is especially true of Doctor Web Kureyt, this curing utility is simply irreplaceable when you need to scan the entire device for viruses.
Dr.Web Online can be useful in more rare cases when you need to scan a specific file and there is no time to download an anti-virus scanner to your laptop or PC.
On our website you can download the Dr.Web CureIt anti-virus, which will be an excellent protection for your personal computer.
This antivirus does an excellent job of detecting and removing file viruses, worms (network or mail), Trojans, macro viruses, spyware, polymorphic viruses and other malware, as well as disinfecting infected files.
Distinctive features are:
Antivirus is an executable file, and to start working with it, you just need to run it on your computer. The downloaded antivirus contains the latest virus database, so it can easily detect malicious programs that have not been noticed by another antivirus. Benefits of Dr.Web CureIt !:
The disadvantages can be attributed to its "disposability": to re-scan the computer, you will have to download a new version of the antivirus, since it does not update automatically. However, this is compensated by the fact that you can use Dr.Web CureIt at any time, and the file itself weighs about 40 MB.
Do you urgently need to download a free Doctor Web scanner? Have you noticed that your previously installed anti-virus package does not cope with the task assigned to it and lets "goals" go into the OS gates?
Just for this case, we give you the opportunity to get instant help.
The page contains a utility necessary in such situations that will conduct a background scan of your system to detect harmful executable files.
Doctor Web can, however, if you need an offline version, Doctor Web scanner will suit you. Ease of use is the key concept, since all that is required of you is to simply download the Doctor Web scanner. Being completely self-contained, it does not require a separate installation and performs all its operations in the background. There are many optional configurations available and the convenient ability to conduct a general OS scan. This "little giant" is able to create healthy competition for a full-fledged antivirus software package. The guarantee that viruses, if any, will be detected is the developer's certificate for safe scanning (ICSA). 
Your more "heavyweight" security guard (the firewall already available on the PC) will not even notice that someone is doing the work for him and has defended himself against virus attacks. In this case, the possibility of "quarrels" between programs is excluded. If you have any questions, there is an intelligibly compiled help on the operations being executed, so even an inexperienced user can check the computer for Doctor Web viruses.
Before you "give the go-ahead" for Dr Web Scanner to start its direct duties, select one of the three treatment modes.
Nevertheless, the utility cannot be called a panacea for all ills, since it checks for already corrupted files in the system, but cannot provide online help. For a more detailed protection program, you still have to download the Dr. Web scanner, only the full version -. We will help you with a solution to this question as well, since you can easily find it in our library.
The development of virus software is happening at such a pace that not all antiviruses can cope with it. Therefore, when a user begins to suspect that malware has appeared on his computer, but the installed anti-virus program does not find anything, portable scanners come to the rescue. They do not require installation, so they do not conflict with the installed protection.
There are many scanners that can easily determine if there is a threat in your system, and some will even clean it of unnecessary files. You just need to download the utility you like, configure or download databases if necessary, run and wait for the result. If problems are found, the scanner will offer you a solution.
Users also use anti-virus utilities when there is no protection on their computer, because it is easier to use a scanner than to constantly load the processor with an anti-virus program, especially on weak devices. Also, portable utilities are convenient, because if you have any problems with the installed protection, then you can always run the scan and get the result.
Dr.Web CureIt is a free utility from the well-known Russian company Dr.Web. This tool is capable of curing found threats or quarantining them.
Kaspersky Virus Removal Tool is a useful and accessible tool for everyone. Of course, it does not provide the same protection as Kaspersky Anti-Virus, but it does an excellent job of dealing with all sorts of malware it finds.
Lightweight utility AdwCleaner can clean your computer of unwanted plugins, extensions, viruses and more. Can fully check all sections. Free and does not require installation.
AVZ Portable Mode can be a very useful virus removal tool. In addition to cleaning from malicious programs, AVZ has several useful functions for convenient work with the system.
Knowing several useful portable scanners, you can always check your computer for viral activity, as well as eliminate it. In addition, some utilities have other useful functions that can always come in handy.
