The FDA is particularly concerned that products that fraudulently claim to cure, treat or prevent serious diseases like COVID may cause consumers to delay or stop appropriate medical treatment, leading to serious and life-threatening harm. In addition to following up with companies that fail to make adequate corrections, the FDA will continue to monitor social media, online marketplaces and incoming complaints to help ensure that the companies do not continue to sell fraudulent products under a different company name or on another website.
Fraudulent COVID products may come in many varieties, including dietary supplements and other foods, as well as products purporting to be drugs, medical devices or vaccines. Products that claim to cure, mitigate, treat, diagnose or prevent disease, but are not proven safe and effective for those purposes, defraud consumers of money and can place consumers at risk for serious harm. Using these products may lead to delays in getting proper diagnosis and treatment of COVID and other potentially serious diseases and conditions.

You have to download the software and install it on a USB flash drive. Kaspersky's malware scanner continues to provide excellent protection from a variety of attacks, new and old. In the November-December round of testing by Germany's AV-Test lab , Kaspersky detected percent of both new "zero-day" and well-known "widespread" malware and had just one "false positive" detection of benign software. Most of the other antivirus brands we review, including Bitdefender, Norton and Microsoft , also had clean sweeps.
Overall, Kaspersky's track record in AV-Test's monthly evaluations is exemplary. Only Norton beat that record, with a single miss on zero-day malware, but Norton tended to have more false positives. Bitdefender had a London-based SE Labs digs a bit deeper, checking whether antivirus software blocks malware from being installed or merely neutralizes it after installation, and scoring accordingly. In the October-December SE Labs round, McAfee also got a perfect score, offsetting a couple of less-than-stellar results earlier in the year.
Trend Micro, which consistently does well on the AV-Test and AV-Comparatives tests, let through two pieces of malware to infect the system; Sophos let through a whopping eight. Bitdefender and ESET were not tested. Each Kaspersky Windows antivirus product has browser extensions for Google Chrome, Mozilla Firefox, Microsoft Edge and Microsoft Internet Explorer to safeguard data typed into websites, warn of phishing attempts and block pop-up ads.

The Clean and Optimize features are included in Kaspersky Internet Security and Kaspersky Total Security to get rid of unnecessary apps, delete duplicate and temporary files and clear browser histories.
Kaspersky software has full and quick scans, a customizable selective scan, an external-drive scan and a vulnerability scan to find system weaknesses. To measure the effect Kaspersky Total Security had on system performance, we used our custom Excel benchmark test, which clocks how long a PC takes to match 20, names and addresses in a spreadsheet. Our Lenovo ThinkPad T test machine had a 2. Before we installed the Kaspersky software, the ThinkPad T took an average of The completion time rose to Kaspersky Total Security imposed a small-to-moderate performance hit on our test system.
During full scans, the benchmark time rose to an average of This was reflected in quick scans as well, with the average benchmark completion time rising to
